With the progress of social and economic development, people's demand for resources continues to increase, from automobiles that require diesel to power plants that require petroleum. In short, oil, natural gas and other resources have become indispensable things in people's daily life, so people gradually invented pipeline transportation methods. Next, I will introduce pipeline construction equipment in detail.
Here is the content list:
l What are the reasons for using pipeline construction equipment
l What is the specific process of pipeline construction
l What pipeline construction equipment is needed during pipeline construction
Due to the large volume of pipeline transportation, most of the pipelines are buried underground, occupying a small area, less terrain and object constraints, and short transportation distances.
Use pipeline construction equipment for sealed transportation, safe and reliable, long-term continuous and stable operation, easy to manage, easy to maintain, and realize remote centralized monitoring.
Therefore, a large number of pipeline laying work has been carried out in various countries, and related companies specializing in pipeline construction equipment have been derived. WINCOO is a company specializing in pipeline construction equipment.
There are many factors that can lead to operational defects in pipeline construction, such as inadequate installation technology, long construction period or insufficient supervision. Relevant technical personnel should be careful, careful, and concentrate on research and judgment when inspecting and accepting pipeline construction equipment.
Provide feedback and resolve the issue as quickly as possible. If the existing safety quality is not reached, the target area should be immediately compensated to ensure that the pipeline construction equipment can continue to operate safely. And maintain the original economic cost.
Specific process introduction:
Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair.
The following pipeline construction equipment is needed during pipeline construction:
l Transport anticorrosive pipe
l Pipe assembly
l Pipe assembly and welding
l Heat shrinkable sleeve (tape) bushing
With the continuous development of society, the demand for pipelines is also increasing, and the pressure on pipelines is increasing. During the installation and operation of pipeline construction equipment, welding is a basic technical job and also a vital job.
The safe and stable operation of pipeline construction equipment plays a key role in the overall pipeline operation. Therefore, increasing attention to the construction quality of pipeline construction equipment can lay a solid foundation for the normal operation of the factory!If you want to know more about high-quality pipe spool fabrication lines, you can also contact us at any time.
The use of pipeline construction equipment is inevitable in the chemical industry. Pipeline installation is an inevitable part of project construction. However, the installation of pipeline construction equipment requires a certain degree of professionalism and pertinence. Relevant departments need to strengthen industrial management and do a good job of quality control of pipeline installation , Lay a solid foundation for my country's industrial development.

Prepare the corresponding technical plan before processing, organize the management and operation personnel involved in processing to carry out training, so that the relevant operators can fundamentally solve the problems existing in the process of processing pipeline construction equipment.
Introduce the safety and environmental protection measures of pipeline construction equipment.
The use of pipeline construction equipment can effectively guarantee the processing quality of steel crane beams, reduce the amount of correction work, reduce production costs, speed up the production rate, and reduce the adverse effects on the welds caused by measures such as the fixed and mandatory correction of semi-finished products during the processing , It has a positive effect on the improvement of the processing technology of steel crane beams.
l Safety measures
Before making steel crane beams, a processing plan or processing technology should be prepared, corresponding safety technical guarantee measures should be formulated, and safety technical clarifications should be made.
① Operators must be familiar with the safety operating procedures of machinery and equipment in the production of pipeline construction equipment and the safety technical operating procedures of this type of work, and operate in strict accordance with the procedures for safe operations.
② The electricity consumption of the production workshop or site must be managed by a full-time electrician and hold a certificate.
③ The electric oxygen welder must obtain the corresponding electric welder qualification certificate.
④ Materials, semi-finished products, and finished products should be slowly and steadily lifted during production, turning over, and lifting.
⑤ Place it to prevent bumping or falling over and crushing people. Lifting personnel must have corresponding qualifications.
⑥ All workers wear protective equipment as required.
⑦ All kinds of pipeline construction equipment must have good grounding and zero connection.
⑧ Establish a full-time safety officer to conduct safety inspections and inspections on the work site, and find unsafe factors, promptly propose and implement corrective measures.
l Environmental protection measures
The installation of pipeline construction equipment is one of the necessary steps in the industrial field, and the installation and construction of pipeline construction equipment is a very important stage in project construction.
Due to the influence of various factors during project construction, there are many problems in the installation of pipeline construction equipment. In order to promote the improvement of industrial pipeline installation quality, certain measures need to be taken to control the pipeline installation quality to ensure the smooth completion of project construction.
① The construction site should be kept clean. All items should be arranged in time and placed in an orderly manner.
② Noise should be controlled during operation, and operation time should be arranged reasonably to reduce the impact on the surrounding environment.
③ The working lights at night should be irradiated into the field, and protective measures should be taken for the welding arc.
④ The oil used in operation machinery shall not be dumped at will to prevent pollution.
⑤ Waste materials, steel materials, welding heads, welding wire heads, etc. left over during operation should be collected separately, treated or recycled in a unified manner.
Introduce the influencing factors in the installation of pipeline construction equipment.
l Bracket installation quality
In the installation of pipeline construction equipment, the installation of the bracket is relatively important, which plays a very good role in the quality of pipeline installation and the normal operation of the equipment. Among them, the installation of the bracket has a certain impact on the overall performance of the pipeline.
For example, the carrying capacity of the scaffold must meet the standard, the sliding surface of the support and the supporting surface have good connection performance, etc. Therefore, the pipeline construction process needs to be carried out according to the engineering construction drawings and pipeline construction equipment installation and construction process specifications to avoid installation Quality has a certain impact.
l Welding quality
Welding in the installation of pipeline construction equipment is also one of the necessary links. The quality of welding affects the overall quality of pipeline installation. Pipe welding can ensure the performance of the undertaking project frame group, thereby ensuring the overall performance of the pipeline. Therefore, precise welding is required in welding, positioning welding position to ensure welding quality, and welding in strict compliance with welding procedures and specifications.
In welding, especially the position of the welding seam, the welding process requirements of the welding workers are very high. The relevant personnel are required to do a good job in welding quality control in this link, and to formulate specific solutions for possible situations to avoid The overall performance of pipeline construction equipment has a certain impact.
l Pipeline anticorrosion
The particularity of the use environment of pipeline construction equipment and the particularity of the use location require the pipeline to have certain anti-corrosion performance. In the pipeline anti-corrosion, the anti-corrosion material will choose paint, and the economical and reasonable pipeline paint can be selected for pipeline anti-corrosion in the process of use.
To reduce the risk of pipeline construction equipment being corroded, paint itself is a corrosion-resistant substance, which is an industrial raw material and anti-rust material for construction. Applying a layer of paint on the surface of the pipeline can extend the service life of the pipeline.
With the continuous development and progress of my country’s science and technology, my country’s demand for oil and gas resources has become greater and greater. In order to promote the development of my country’s economic construction and meet people’s normal lives, ground construction is an important link in the process of oilfield development and exploration to ensure production The key means of safety, especially the installation of pipeline construction equipment and the construction technology of gathering pipelines, play an important role.

On the characteristics of the corporate piping system.
Among all the equipment in power plant operation, pipelines are one of the most indispensable equipment, which are concentrated in EH oil pipelines, lubricating oil pipelines, jack shaft oil pipelines and boiler fuel oil pipelines. Such pipelines are generally ordinary 20 steel. Or 18-8 type stainless steel material, the related pipeline construction equipment has rich specifications and small pipe diameter.
The number of welds on the upper level of pipeline construction equipment is relatively large, and at the same time they are densely distributed; some pipeline welds are not easy to find and are relatively hidden, which often causes some problems during welding operations; especially stainless steel, which is high in chromium. Alloys and material types are unusual. Usually, when pipeline construction equipment is used, relatively large intergranular corrosion and hot cracking will occur, and the difficulty coefficient when completing welding work is relatively large.
About the characteristics of pipeline construction equipment welding.
Welding of pipeline construction equipment requires argon arc welding. For oil pipelines with a diameter of less than 60 mm or a thickness of 5 mm, the welding process for pipeline construction equipment can be full argon arc welding; if the diameter of the pipeline is greater than 60 mm If the thickness is greater than 5 mm, the relevant technicians need to change the welding process to argon arc welding bottom arc welding cover.
The key reason for this is that in stainless steel, the content of cr is already above 13%. A little carelessness will cause oxidation or excessive burning of the welding root. Therefore, when welding pipeline construction equipment, it is necessary to Argon filling or mixing of inert gas is carried out inside, so as to achieve the protective effect and ensure the welding construction quality of pipeline construction equipment.
Analyze the causes and characteristics of common problems during welding of pipeline construction equipment.
In recent years, some power plants have been shut down due to pipeline weld leaks or due to the quality of system welds. The existence of such phenomena will not only have a very bad impact on the overall operation, but also make the safety of the plant fall into threat situation.
In the construction of pipeline construction equipment welding engineering, there are two defects in welding, namely surface and internal defects. Surface problems can be discovered by the naked eye, but internal defects cannot be discovered in time by only relying on the senses. At this time, technicians and detection instruments are required to inspect pipeline construction equipment. Only through accurate inspection of the instrument can the problem be clearly known. Where is the root cause.
The welding quality of pipeline construction equipment will have a great impact on the operation of the unit. In other words, if the operation of the unit does not stop, it is probably because the pipeline construction equipment has welding quality problems.
Why do these problems occur in pipeline construction equipment? The reasons can be found from the following aspects:
l Because the pipeline construction equipment design unit only gave the system diagram but not the layout diagram, the construction personnel carried out the construction based on the site conditions and construction experience. The welding technicians did not know the location and quantity of the welding joints, so they could only make visual inspections or estimates based on their own experience. There will be a shortage in the number of weld inspections, which increases the probability of missing weld inspections;
l In the welding process of pipeline construction equipment, relevant technical personnel did not pay much attention to the particularity of the pipeline medium of the oil system, resulting in a low proportion of non-destructive inspections and potential safety hazards;
l When inspecting the welds of pipeline construction equipment, the relevant technicians usually only pay attention to the welds of the main parts and start the inspection, ignoring the inspection of other common welds, which may easily cause omissions;
l There are irregularities in the direction and layout of construction pipelines and brackets of pipeline construction equipment, and even stress and other reasons. As a result, the weld is not only the weakest part of the pipeline, but also the source of the first problem;
l Because the construction period of pipeline construction equipment is tight or there are requirements on the schedule, some who do not have welder skills or do not hold welder certificates will also temporarily serve as welding technicians. Such personnel who have not received professional welding training usually operate They are all conventional and ordinary welding skills. In the welding operation of pipeline construction equipment, there are problems such as insufficient sense of responsibility and low attention. At the same time, the quality of the plumber’s counterpart is not up to the standard and the awareness is relatively weak. Such problems will lead to pipeline construction equipment. There are quality problems and safety hazards in the weld joints.
In recent years, large-scale pipeline projects have started one after another, and the level of mechanical equipment of pipeline construction solutions has been steadily improved. However, the management of pipeline construction equipment on the construction site has not kept up with the speed of pipeline engineering and mechanical equipment updates, resulting in a high rate of equipment failure and maintenance on the construction site. High cost, low technical performance and low utilization rate. In response to these situations, explore standardized maintenance in the management of pipeline construction equipment.
Here is the content list:
l Regarding the maintenance status of pipeline construction equipment at the construction site.
l What are the specific measures to achieve standardized maintenance of pipeline construction equipment?
l How can companies ensure the effective implementation of pipeline construction equipment maintenance procedures?
l Objective conditions cause pipeline construction equipment maintenance to be unable to be carried out normally. Pipeline construction has a large geographic span, harsh construction environment, and increased equipment component wear, which directly affects the stability and reliability of the equipment, causing the mechanical equipment to lose basic performance and fail to operate normally. In addition, the current project schedule is very tight. In order to catch up with the schedule and grab the schedule, it is difficult to keep up with the daily maintenance of pipeline construction equipment.
l Subjectively neglect.The subjective factor that causes the on-site pipeline construction equipment maintenance to be unable to be carried out normally is that the relevant units and management personnel do not pay attention to the equipment management. In many construction companies, the management of the company, project management, and construction crews do not pay much attention to the management of pipeline construction equipment, believing that the equipment is just a tool for wear and tear during the construction process, which emphasizes use rather than maintenance. Many construction projects and construction units arbitrarily extend the maintenance cycle of pipeline construction equipment, reduce the grade of accessories and lubricants, so that the overhaul cycle of the engine is shortened due to human factors, project maintenance costs increase, and the cycle of equipment failures is prolonged. The technical performance of pipeline construction equipment has severely declined.
l Weak technical management capabilities.The quality of equipment maintenance has declined. First of all, many on-site management personnel's understanding of on-site maintenance of pipeline construction equipment is still at the level of "replacement of the three oil filters", and the maintenance of the engine, chassis and working devices is not included in the pipeline construction equipment. Maintenance plan in progress. Secondly, the equipment operators and maintenance personnel do not have a high level of basic skills and cannot complete the overall overhaul of pipeline construction equipment with high quality.
Repair and maintenance of pipeline construction equipmentt is very important. First of all, we must regularly check, maintain and replace vulnerable parts. WINCOO will provide manuals with the machine, such as high-performance pipeline construction equipment, automatic pipeline construction equipment, small pipeline construction equipment, high-precision pipeline construction equipment, easy-to-maintain pipeline construction equipment, etc. The following are specific measures:
① In view of the low maintenance quality of pipeline construction equipment, by compiling comprehensive, meticulous, and highly operable procedures, not only can we clarify what tasks the pipeline construction equipment operators and maintenance personnel need to do daily maintenance and secondary maintenance, but also tell them How to work.
② While compiling maintenance procedures for pipeline construction equipment, the company also compiled checklists for standardized maintenance and management of various types of pipeline construction equipment, making it the main basis for management departments at all levels to inspect pipeline construction equipment, and unify inspection standards and assessment scores. Standards to facilitate the recording, filing and review of equipment inspections and inspection results.
① Personnel training. Strengthen the learning and training of pipeline construction equipment supervisors,managers, and maintenance personnel to change their concepts, fully understand the importance of maintenance to the use of equipment, and cultivate long-term perspectives and implementation of pipeline construction equipment maintenance, and completely avoid the first phase The situation where the project "eaten" a batch of pipeline construction equipment. Through regular learning and training, the standardized equipment maintenance procedures are deeply rooted in the hearts of the people, and become the working guidelines and working habits of operators and repairers, rather than the work requirements of the superior management department. Through learning and training, to a certain extent, the sense of responsibility and dedication of managers at all levels has also been improved.
② Innovate the system of deciding people and machines. In order to mobilize the enthusiasm of equipment operators to rationally use pipeline construction equipment, earnestly maintain pipeline construction equipment, and sincerely care for pipeline construction equipment, the company strictly implements the system of determining personnel and equipment, and integrates the personnel and equipment management information system to control the attendance and equipment of the operators. The intactness of the pipeline construction equipment is linked together, and the man-hours for equipment maintenance are included in the actual man-hours of the operator.
① Increase the intensity of rewards and punishments for pipeline construction equipment inspection. In order to ensure the implementation of the standardization of pipeline construction equipment on-site maintenance, the company pays special attention to the intensity of inspection rewards and punishments for pipeline construction equipment when revising the management system.
② Link the maintenance of pipeline construction equipment with bonuses. In order to motivate the construction unit to use and maintain the pipeline construction equipment, the project department regards equipment maintenance as an important assessment index when formulating the economic responsibility system assessment, guiding the construction unit to use the maintenance pipeline construction equipment rationally, controlling the construction progress and avoiding the problem to the greatest extent.
In order to ensure that pipeline construction equipment maintenance procedures can be effectively implemented, the company has formulated corresponding management systems and adopted specific measures to supervise the implementation of these systems.
l Divide maintenance responsibilities. In the management system, the corresponding responsibilities of equipment operators, pipeline construction equipment maintenance personnel, unit equipment managers, and project pipeline construction equipment managers are clarified, and these responsibilities are written into the maintenance procedures manual of each type of equipment, so that all levels of pipeline construction equipment Managers can see what they should do every day and how to record their work in the maintenance procedures.
l Promote standardized pipeline construction equipment maintenance procedures. Implement standardized equipment maintenance organization processes in each construction project to ensure smooth equipment maintenance channels and optimize the maintenance force of the entire project.
l Establish a professional maintenance team. The project department mobilizes skilled fitters, electricians, and repairers to form a professional maintenance team, which is conducive to the unified scheduling of maintenance forces for the project, and ensures low failure rate and high utilization of pipeline construction equipment.
What is more? WINCOO provide not only pipeline construction solutions, but also pipe spool fabrication solutions for customers from everywhere!

Tank welding machine is the process of joining metal parts using various fusible alloys. The melting point of the solder is lower than that of the material to be soldered, so that the part will end the soldering through inter molecular contact on its surface without being melted.
Here is the content list:
l What is the working principle of tank welding machines?
l What is the purpose of using tank welding machines?
l What are the application significance of tank welding machines?
What is the working principle of tank welding machines?
Tank welding machines can be divided into soft welding and hard welding. The temperature of soft welding is lower than 450℃, and the temperature of hard welding is higher than 450℃. Hard welding is usually used for metals such as silver, gold, steel, copper, and its welding point is much stronger than soft welding, and its shear strength is 20 to 30 times that of soft welding. The above two types of thermal connections usually use the term soldering, because in both cases molten solder is written into two elongated gaps between the clean and close solid metal surfaces of the device.
Tank welding machines ensure the continuity of the metal. On the one hand, two metals are connected by bolts or physical attachments to each other, showing a strong metal whole, but this connection is not continuous. Sometimes if there is an oxide insulating film on the metal surface, they may even Right or wrong physical contact.Another disadvantage of mechanical connection compared with welding is that the contact surface continues to oxidize, resulting in an increase in resistance. In addition, vibrations and other mechanical shocks can also loosen the joint. Welding eliminates these problems. The tank welding machines do not move relative to each other, the contact surface will not be oxidized, and the continuous conduction method can be maintained.
What is the purpose of using tank welding machines?
Tank welding machines welding is a process of fusion between two metals, mainly for the purpose of dissolving some of the metal in contact with the solder in the molten state, and the surface of the metal being welded often has a thin oxide film that cannot be dissolved by the solder. The flux is used to remove this oxide film. The tank welding machines welding process usually includes:
l 1) Melting of the flux to remove the oxide film on the surface of the welded metal;
l 2) Melting the solder makes the impure substances and lighter flux suspended in it float to the surface;
l 3) Some dissolve some metal connected with solder;
l 4) Cool and end the melting of metal and solder.
Through temperature changes, humidity, vibration, etc., even a bad solder joint can cause some or all of the system to lose control. There are countless welding points in the equipment, and the reliability of these welding points should even be higher than the equipment itself.
For the purpose of using tank welding machines, research in this area has led to the addition of knowledge of materials and their properties, and many developments have been made in the possible welding processes. Welding technology is an accompanying technology.
With the development of the electronics industry, more useful packaging technologies and smaller components will certainly continue to emerge. Welding technology will also continue to be developed to meet the needs of the electronics industry and environmental issues. This is why welding is becoming more and more professional for technology professors who work in the electronics industry today!
What are the application significance of tank welding machines?
The auxiliary equipment of the tank welding machines includes gas welding glasses to prevent the operator from being damaged by the ultraviolet, infrared or other rays generated by the welding arc or other welding energy, the mask to protect the eyes, face and neck of the welder during arc welding, white work clothes, welder gloves and protective guards.
l Energy efficient.
The energy saving of the electric welding machine is embodied in two aspects: energy saving at no load and energy saving at load. According to relevant statistics, in 2008, the demand for tank welding machines in the domestic welding industry was 890,000 units. If all electric welding machines are used, it can directly save 43,000 tons of copper, 64,000 tons of steel, and save 680 million KW.H of electricity. It saved 566,500 tons of coal, 10.34 million tons of water, and reduced 1,144,500 tons of CO2 emissions. It can be seen that vigorously promoting tank welding machines has huge economic and social benefits.
l Stable performance
Since the working frequency of the tank welding machines is above 20KHZ, it has a faster response speed, and the droplet transfer can be subdivided into multiple stages for control. For CO2 gas shielded welding, spatter can be greatly reduced. For pulsed melting pole MIG/MAG welding, the stability of jet transition can be effectively controlled, and the droplet transition and the movement of the wire feeding mechanism can be combined to further control the melting. During the dripping transition process, a good weld formation is obtained and the welding performance is stable. These are things that traditional rectifier welding machines cannot do.
l Centralized control
The tank welding machines uses a large number of digital controllers such as single-chip microcomputer, DSP, FPGA, etc., and realizes the network communication between multiple welding machines or the upper computer and the welding machine through Ethernet and field bus. It not only solves the problem of coordinated operation of multiple welding machines, and facilitates centralized control in the welding process, but also realizes the setting or monitoring of remote welding machine parameters, making remote fault diagnosis and maintenance of tank welding machines possible.
The installation of pipeline construction equipment is one of the necessary parts in the pipe construction solution, and the installation and construction of pipeline construction equipment is a very important stage in project construction. Due to various factors in the project construction, there are many problems in the installation of pipeline construction equipment. To promote the improvement of the quality of industrial pipeline installation, certain measures need to be taken to control the installation quality of pipeline construction equipment to ensure the smooth construction of the project.
Here is the content list:
l Regarding the quality inspection of pipeline construction equipment installation.
l What are the quality control measures in the installation of pipeline construction equipment?
l Regarding the quality control of pipeline construction equipment after construction.
The sequence of installation of pipeline construction equipment is:
Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair .
After the installation of pipeline construction equipment is completed, quality inspection is required. After pipeline construction equipment is installed and put into use, regular monitoring is required. Generally, radiographic inspection is used to inspect the quality of pipeline installation. This monitoring has a very good effect on the internal inspection of welded joints. It is widely used in the field of construction equipment installation. This method can also be used to make the quality of the pipeline meet the assessment standard.
Before installing pipeline construction equipment, clarify the construction plan of the construction technicians, use GB/T as the standard, and carry out construction in accordance with national standards and specifications; during the installation of pipeline construction equipment, strictly review the drawings for defects to ensure the rationality of the drawings, and the construction unit It is also necessary to make preparations for pipeline installation and construction, pipeline lumber, welding inspection, construction site management, etc.
Strictly follow the relevant requirements of pipeline construction equipment and pipeline construction requirements to improve the quality of construction. In order to ensure the quality of pipeline installation, quality control is required for key parts such as welding materials, welding processes, and welding seams to ensure pipeline construction equipment. Welding consumables, brands, specifications, etc. are required by the plan design, which are consistent with the project construction requirements to ensure the quality of installation.
① After the pipes, accessories and raw materials used for pipeline construction equipment enter the construction site, the supervisors shall check and accept them on site, and store the materials after passing the acceptance.
② Pipe joints and semi-finished products of pipeline construction equipment should be guaranteed not to be damaged during transportation and storage. When unloading, handle with care and not collide with each other; choose a flat place for stacking pipe joints.
③ The storage temperature of the rubber ring of pipeline construction equipment is between -5 and 30 degrees Celsius. It should not be exposed to ultraviolet light source and keep away from the heat source; the rubber ring and the items that easily affect the rubber ring should not be put together. If the pipeline construction equipment is being constructed In winter, hard rubber rings are not allowed.
④ For trench excavation in open-cut pipeline engineering, the section should meet the design requirements of construction quality, the original soil at the bottom of the trench should not be damaged, and the mechanical excavation should reserve a 200-300mm soil layer for manual excavation and leveling, and the bottom of the trench can be soaked by water And frost damage, if there is gravel soil, lime soil to backfill, the trench wall should be leveled to meet the requirements of construction design.
⑤ For concrete construction, when the pipe seat and flat foundation are poured in layers, the flat foundation should be shaved and rinsed; the concrete should be prevented from segregation, and the concrete should be cured after pouring.
⑥ When pipeline construction equipment is installed, visual inspection and internal cleanliness of the pipeline must be inspected.
⑦ The flexibility of pipe joints must meet the design requirements, and the rigidity must also meet the requirements.
⑧ In the stage of backfilling, the backfill height between both sides of the pipe and the top of the pipe before the hydraulic test of the pressure pipeline is greater than 0.5M, and the pressure-free pipeline shall be backfilled after the closed water test and the closed gas test have reached the standard.
After the completion of the pipeline construction equipment, the finishing work will begin. The unit needs to organize personnel to review the material documents involved in the pipeline installation, project reports, etc.; after the completion of the project, debugging and quality appraisal are required, and the pipeline professionals are organized to conduct quality appraisal of the installed pipelines. The dynamic control of the links will protect the completed pipelines.
In the later stage of the installation of pipeline construction equipment, in order to ensure the smooth completion of the project, the quality of the pipeline needs to be tested again to ensure that the pipeline installation does not have problems such as tilt and cracks, the welding parts are of good quality, and the pipeline is unobstructed. In the later period after the completion of the project, it is necessary to sort out each project data and work files involved in the pipeline construction, do a good job of archiving and backup to evaluate the quality of the pipeline, do a good job in risk control, and carry out the acceptance of pipeline construction equipment.
There are many influencing factors in the installation of pipeline construction equipmentt, so reasonable measures need to be taken to monitor and control every aspect of pipeline construction equipment. With the continuous expansion of the pipeline construction equipment construction industry, the use area is also expanding. Due to the importance of pipeline use, it is necessary to control the pipeline installation quality to ensure that the installation quality reaches the ideal standard!
