As we all know, industrial buildings include a series of projects, such as oil refineries and chemical plants and power plants. This type of structure involves dense pipe spool fabrication lines, which connect various equipment and transport process fluids and gases.
Here is the content list:
l Introduction of two engineering stages of Pipe spool fabrication line.
l The installation and welding of Pipe spool fabrication line can be divided into two types
l Why are pipes prefabricated in the Pipe spool fabrication line?
Due to the compressed construction period and limited on-site space, industrial construction projects rely heavily on off-site manufacturing and assembly. Therefore, the pipe spool fabrication line is divided into two stages: pipe prefabrication and on-site installation.
Pipe spool fabrication line timely supply of spools to the module yard and installation site is the key to the success of the entire project! First introduce the pipeline prefabrication stage of the pipe spool fabrication line.

The pipe spool fabrication line is made from many raw pipes and pipe fittings in the manufacturing plant. Cut the unprocessed pipe to the required size, then move it together with the pipe fittings to the fittings table, where certain components are assembled together (ie temporarily connected), and the final sub-assembly (part of the final pipe) The welding operation (ie permanent connection) will be continued, and then returned to the assembly table and assembled with other spool components to form a pipe spool fabrication line.
l Coil and welding
l Positioning and welding
Rolling assembly and welding in the pipe spool fabrication line means that the main pipe can be rotated by the rolling mill, and the assembler or welder can perform the operation without changing its position. When the branch of one or more main pipes exceeds the welding position, Positional assembly and welding can be performed.
In addition, under the restriction of the removal of the pipe spool fabrication line, the assembler or welder must move around the main pipe to complete the assembly or welding. Positioning assembly and welding usually take more time than roller assembly and welding. Minimizing the number of positioning and welding is one of the goals of the pipe spool fabrication line sequence.
Workshop prefabrication of the pipe spool fabrication line is an effective method that can reduce on-site installation costs while providing the highest quality finished products. Pipe spool fabrication line usually uses flange connection to facilitate connection with other spools.
The manufacturing of these pipe spool fabrication line is usually performed by a professional manufacturing company equipped with the required infrastructure. As a professional manufacturer, WINCOO works according to the defined quality management standards to ensure the accuracy of manufacturing, so as to realize the on-site drawstring installation and maintain the required technical parameters defined by the customer!If you want to know more about high-quality tank welding machine products, you can also contact us at any time.
Pipeline construction equipment plays a very important role in the development and exploration of oil and gas resources. To ensure the production safety of oilfield enterprises, it is necessary to improve the quality of surface pipeline construction equipment installation and gathering pipeline construction. Next, it mainly elaborates the relevant installation points of pipeline construction equipment, analyzes and introduces the construction technology of pipeline construction equipment, and lays a solid foundation for the development of oilfield surface construction.
Here is the content list:
l Regarding the necessity of installing pipeline construction equipment.
l About the procurement and acceptance of pipeline construction equipment.
l What are the main points of pipeline construction equipment installation?
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.

Anyone with a little mechanical knowledge knows that energy can be transformed into each other. It is best to apply this knowledge to the tank hydraulic jacking system to explain the power loss of the hydraulic system. Next, we will introduce in detail how to maintain the tank hydraulic jacking system.
Here is the content list:
l Maintain the tank hydraulic jacking system from the perspective of power source.
l Maintain the tank hydraulic jacking system from a pressure perspective.
l Maintain the tank hydraulic jacking system from the perspective of speed regulation.
Maintain the tank hydraulic jacking system from the perspective of power source.
On the one hand, the power of tank hydraulic jacking system will cause energy loss and reduce the overall efficiency of the system. On the other hand, this part of the energy lost will be converted into heat energy, which will increase the temperature of the hydraulic oil and the deterioration of the oil. The tank hydraulic jacking system is malfunctioning. Therefore, when designing a tank hydraulic jacking system, under the premise of meeting the requirements of use, full consideration should be given to reducing the power loss of the system.
First of all, considering the power source-pump, considering the diversified working conditions of tank hydraulic jacking system actuators, sometimes the system requires large flow and low pressure; sometimes it requires small flow and high pressure.
Therefore, it is appropriate to choose a pressure-limiting variable pump, because the flow rate of this type of pump changes with the change of the system pressure. When the tank hydraulic jacking system pressure decreases, the flow rate is relatively large, which can satisfy the fast stroke of the actuator. When the tank hydraulic jacking system pressure increases, the flow rate decreases accordingly, which can meet the working stroke of the actuator. This can not only meet the working requirements of the actuator, but also make the power consumption more reasonable.
Maintain the tank hydraulic jacking system from a pressure perspective.
Second, when hydraulic oil flows through various types of hydraulic valves, there will inevitably be pressure loss and flow loss. This part of the energy loss occupies a large proportion of the total energy loss.
Therefore, reasonable selection of hydraulics and adjustment of pressure valve pressure are also an important aspect of reducing power loss. The flow valve is selected according to the flow adjustment range in the tank hydraulic jacking system and its minimum stable flow can meet the requirements of use. The pressure of the pressure valve should be as low as possible when the hydraulic equipment is working normally.
Maintain the tank hydraulic jacking system from the perspective of speed regulation.
Third, if the actuator has speed regulation requirements, when selecting a speed regulation loop, it is necessary to meet the speed regulation requirements while minimizing power loss. The speed control circuits of common tank hydraulic jacking system mainly include: throttle speed control circuit, volume speed control circuit, volume throttle speed control circuit.
The throttling speed control loop in the tank hydraulic jacking system has large power loss and good low-speed stability. The volumetric speed control circuit has neither overflow loss nor throttling loss, which has high efficiency but poor low-speed stability. If the tank hydraulic jacking system needs to meet both requirements at the same time, a volume throttling speed control circuit composed of a differential pressure variable pump and a throttle valve can be used, and the pressure difference between the two ends of the throttle valve should be as small as possible to reduce pressure loss.
In summary, a reasonable choice of hydraulic pressure is crucial. When the hydraulic oil flows in the pipeline, it will exhibit viscosity, and when the viscosity is too high, it will generate greater internal friction, causing the oil to heat up, and at the same time increase the resistance when the oil flows. When the viscosity is too low, it is easy to cause leakage, which will reduce the volumetric efficiency of the tank hydraulic jacking system.
Therefore, generally choose oil with suitable viscosity and good viscosity-temperature characteristics. In addition, when the oil flows in the pipeline, there are pressure loss and local pressure loss along the way. Therefore, when designing the tank hydraulic jacking system pipeline, the pipeline should be shortened as much as possible while reducing the number of bends.
The above are the recommended maintenance points to avoid the power loss of the oil tank hydraulic jacking system. However, there are many factors that affect the power loss of the tank hydraulic jacking system. Therefore, if specific maintenance is performed on the storage tank hydraulic jacking system, other requirements should be considered comprehensively!
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.
