Ground construction is an important link in the pipeline development and exploration process and a key means to ensure the production safety of pipeline engineering, especially the installation of pipeline construction equipment and gathering pipeline construction technology, which plays an important role.
Production safety is closely related to the installation quality of pipeline construction equipment. At the same time, the transportation of resources has a direct impact on the construction technology of gathering pipelines. Therefore, only the continuous improvement of pipeline construction equipment installation and gathering pipeline construction technology can promote the development of resources and sustainable development.
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, it is necessary to strengthen management of the construction of pipeline construction equipment.
Through our analysis, it is found that the quality of products and product life of a company is closely related to the installation quality of pipeline construction equipment. Therefore, during the installation of pipeline construction equipment, the quality of pipeline construction equipment must be checked, especially the key to the equipment. Comprehensive corrosion control.
In the process of purchasing technical parts, the model, quantity, type, specifications, etc. must be carefully checked, and must comply with relevant national and corporate standards. When purchasing, try to directly sign contracts with purchasing companies to control procurement costs and ensure product quality.
Therefore, the pipeline construction equipment must meet the actual construction requirements when purchasing, and the quality of the pipeline construction equipment must be strictly controlled and accepted after entering the site. Only after all the inspections are qualified, the pipeline construction equipment can be installed on the site to ensure Safe use of equipment during construction!
During the installation of pipeline construction equipment, professional installers must perform operations. Installers must first inspect the installation site, work out a scientific and reasonable construction plan, and choose the correct installation method.
Measured according to the positioning axis of pipeline construction equipment. At present, there are two equipment installation methods that are often used in ground construction. One is to directly install on an existing building; the other is to conduct strict and precise measurement on the location of the equipment.
Check the balance error, vertical error, dimensional error, and axis error of key components in pipeline construction equipment one by one. At the same time, if you want to closely link the ground construction equipment with the construction base, you must strictly control the grouting quality of the grouting layer, and further strengthen the strength of the grouting layer. After the installation of the pipeline construction equipmentt, the safety of use must be carried out. Detect and avoid equipment failure during use, causing safety accidents, and bringing huge economic losses to the enterprise.
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.

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.

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 order to ensure the safe daily operation of equipment, the welding construction of pipeline construction equipment must be strictly controlled to reduce the probability of problems. However, the power plant will inevitably encounter some problems during operation, and these problems are often caused by operational defects in the welding construction during the installation of pipeline construction equipment. There are also many factors that lead to operational defects in welding construction, such as inadequate installation technology, overtime or insufficient supervision.

Attention and prevention points in welding construction of pipeline construction equipment.
Inadequate operation during welding of pipeline construction equipment will leave hidden dangers to engineering safety. When conducting inspection and acceptance of metal welds, relevant technicians need to be careful, careful, and concentrate on studying and judging, and feedback and solve problems as soon as possible . The existing places where the safety quality does not meet the standards should be immediately compensated to ensure that the unit can continue to operate safely and maintain the original economic costs.
When performing welding operations on pipeline construction equipment, technicians must take professional welding measures. In addition, they must also control the quality of plumbing counterparts. In particular, the quality of joints and arc closing must be strictly controlled by technicians.
Therefore, the weld must not be welded in one layer, but two or more layers must be welded, and the inter-level joints must be staggered by more than 10 mm. In order to be able to deal with the weld bead oxidation site, the internal argon must be in place when the stainless steel pipe is welded. At the same time, technicians must strictly control the temperature between layers, and use water cooling for welding if necessary.
Factors that cause problems during pipeline construction equipment construction.
At the same time, it is necessary to find out which environmental factors will affect the welding work of pipeline construction equipment, especially some special welding methods and welding materials have certain requirements on the environment. For example, alkaline electrodes should be in an environment without water, rust and oil, while argon arc welding should be in an environment without wind, water, rust and oil.
According to the welding conditions of different pipeline construction equipment, corresponding protective measures should be taken to ensure welding. stable quality. The welding of pipeline construction equipment usually involves the connection between the weldment and the counterpart, and the quality of the connection will directly affect the quality of the welding.
In order to clarify their responsibilities, the technicians of pipeline construction equipment must inspect and accept the corresponding weldments before starting welding. For peers with unqualified quality, welding technicians can choose to refuse welding.
Violations of regulations must be dealt with seriously. In addition, during spot welding, due to the unstable welding equipment, corresponding stresses will be generated under normal conditions and defects are likely to occur. It is the weakest place in the entire welded joint. We must let welders with relevant qualifications perform spot welding operations.
Dealing with welding quality problems of pipeline construction equipment.
There are always problems of this kind during pipeline construction equipment construction, leading to continuous occurrence of welding quality problems. Once there is a quality problem, we can start from these aspects: First, we must investigate and analyze the cause of the problem. In addition to investigating the person directly responsible for the problem, we must also find out the related reasons.
For example, the management of the construction site is not in place or scientific, and the management personnel are negligent. They should not be deceived by the surface phenomenon of the problem, but should be investigated in depth. When penalties are carried out after the investigation, in addition to punishing the relevant responsible persons, it is also necessary to formulate rewards for those who find problems in advance.
The welding acceptance of pipeline construction equipment is the main link in the welding construction process to control the quality. During the inspection, different inspection methods and inspection ratios need to be adopted for different types of welds to meet the welding quality control requirements.
After the inspection, it is necessary to accurately feedback the specific situation with the relevant process at the first time, and find the cause of the welding quality problem in time, and give improvement measures and suggestions to ensure that the welding quality reaches the standard. The inspection work is usually easily restricted by the inspection environment and conditions.
Therefore, testing can only be carried out on finished products. Generally, there are two popular testing methods: destructive testing and non-destructive testing. In actual work, non-destructive testing is usually adopted, which is also the most common one. In non-destructive testing, air tightness testing and non-destructive testing are often used.
Finally, make a summary of the problem and propose rectification measures. The content of the measures must be implemented, and the time, progress, and person responsible for the rectification shall be clarified. Otherwise, the effect of the rectification will be poor. In short, in the pipeline construction equipment construction process, strictly implementing the welding process, controlling the quality of the counterpart, and reasonably requiring the construction period should be the main points of pipeline construction equipment control. At the same time, in the pipeline construction equipment process, set up the welding process witness point and do a good job in process monitoring.
Due to the large demand of oil and natural gas, not all places have these materials, so in order to transport and storage convenient, people use pressure vessels to store and transport.So how pressure vessels are airtight depends on the welding machine.The large volume of the pressure vessel and the amnesty of storage products require that the welder can move up and down, and the length is long enough.Today we are going to introduce such a special welding pressure vessel welding machine.
