It is not easy to maintain pipe spool fabrication line. Whether it is used in the oil and gas industry, power plants, chemical plants or other infrastructure projects, the pipe spool fabrication line usually contains hundreds of components and thousands of processing steps. Therefore, it is very important to maintain the pipe spool fabrication line.
Here is the content list:
l Line maintenance
l Pipeline repair
l The advantages of choosing WINCOO to repair and maintain the tube shaft production line.
The maintenance of the pipe spool fabrication line includes inspection of pipeline corrosion and anti-corrosion; inspection of pipelines for oil leaks; inspection of valves along the line; inspection of the loss of hydraulic structures and coatings along the line; inspection of signs of damage, etc. Once the pipeline line and equipment are found to be faulty, the pipe spool fabrication line should be repaired or updated in time.
Due to the long line of the pipe spool fabrication line, it may be damaged by man-made and natural disasters at any time. Therefore, it is necessary to conduct line inspection and maintenance of the pipe spool fabrication line frequently. In addition, there is also a dedicated pipeline maintenance team equipped with necessary mobile equipment, earth moving equipment, welding and blocking equipment, and communication tools, so that they can be prepared for emergency repairs at any time.
l Pipe spool fabrication line anti-corrosion inspection
Routine pipe spool fabrication line anti-corrosion inspections include: regularly testing the protection potential along the pipeline; using an anti-corrosion layer detector to check the integrity of the pipe's anti-corrosion layer on the ground. The inspection of corrosion in the old pipeline is a complicated task, and it is usually carried out with a cup-type pipe cleaner with a testing instrument.
The testing equipment of the pipe spool fabrication line includes a magnetic flaw detector to detect internal corrosion and an ultrasonic thickness gauge to detect the thickness of the pipe spool fabrication line. The running distance is calculated by the number of revolutions of the support wheel, and all the tested parameters are converted into signals and recorded on the tape. After the inspection, the tape is interpreted by the computer, which can indicate the corrosion degree and location of the pipeline.
l Pipe spool fabrication line oil leakage inspection
Mainly rely on line inspectors to inspect the pipe spool fabrication line. In order to ensure the safety of residents and enterprises along the route, all countries have formulated oil and gas pipeline safety technical specifications, which are strictly supervised and implemented by government departments. If leakage occurs in the pipe spool fabrication line, report it to the competent authority immediately and check the cause of the accident on site.
Heavy rains and floods will cause soil erosion on the pipe spool fabrication line and damage to the embankment, resulting in exposed, suspended or even broken underwater pipelines. These situations are mainly discovered by line inspectors. Line patrol personnel usually walk on the ground or fly in the air to patrol the line. The maintenance work of the pipe spool fabrication line must be implemented in accordance with the detailed line engineering as-built drawing!
The most prominent part of the maintenance of the pipe spool fabrication line is the handling of large accidents such as leak repair and pipe replacement. If the leak is caused by corrosion and perforation, you can use a fixture to plug the leak on the pipe and then perform repair welding.
If the pipe spool fabrication line is severely damaged or deformed, the pipe must be removed and replaced with a new pipe section. The oil and gas leaked when the pipe is cut off can easily cause a fire. When cutting off the pipeline at low places, it is necessary to prevent a large amount of oil and gas from leaking. Mechanical plugging devices are often used to plug the pipelines, and emergency repair operations are carried out without stopping the transportation.
The mechanical plugging method is to open a hole on the upstream and downstream of the pipe section to be replaced, and insert a plug with a cup into each hole to isolate the oil or gas at both ends, and then drain the oil in the damaged pipe section. Or gas, cut off the pipe section with a mechanical cutter, then insert two pigging balls into the cuts at both ends, and fill the gap between the pigging balls and the plug with nitrogen to prevent explosion during welding.
Put the equipped new pipe spool fabrication line in place, align and weld. After welding, lift the occluder out of the pipe and close the opening to complete the plugging and pipe replacement work. After the pipe spool fabrication line is repaired and operated, two pig balls will be recovered in the pig receiver tube of the downstream station. When plugging and replacing a pipe section, the bypass pipe can be drawn out before plugging to ensure uninterrupted pipe spool fabrication line delivery during the entire pipe replacement process.
The advantages of choosing WINCOO to repair and maintain the tube shaft production line.
Since the pipe spool fabrication line contains thousands of steps, each step is an opportunity for error. Therefore, carefully plan before sending the request for quotation (RFQ) to the manufacturer and proceed during the manufacturing of the pipe spool fabrication line. Careful monitoring and acceleration of the process contribute to successful, timely and profitable results. Adequate planning, preparation and scheduling early in the process is beneficial to project owners, builders and tube and shaft manufacturers!

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.
