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.

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 installation of tank hydraulic jacking system shall not use aluminum conductor and screw steel as grounding body or underground grounding wire. The wires connected by bolts must have one end. There are three main ways to ground:
① The grounding body adopts regular grounding piles, or 33*4.5 long 1.5m steel pipe, or 70*70 long 1.5m angle steel.
② The grounding plate is made of steel plate or other ductile metal plate, with an area of 1 square meter and a depth of 1.5m from the ground.
③ Copper conductors with a cross-section of not less than 28 mm or steel conductors with a cross-section of not less than 50 mm are buried in the wire slot, and the buried length is determined by the grounding resistance.
In the above three methods, the cross-sectional area of the copper wire drawn from the grounding body should not be less than 25. If the soil is poorly conductive, sodium chloride (table salt) can be buried in the soil. Then fill it with water. For the tank hydraulic jacking system, each rail must be grounded, the two rails should be connected by a wire, and the two rails should also be electrically connected.
l About tank hydraulic jacking system safety device:
1. A safety device that prevents the sling on the hook from slipping off automatically.
2. Install a compression spring sheet at the opening of the hook head to close the opening. This spring sheet can only be pressed down and cannot be turned up after the sling is put in. It can prevent the sling of the tank hydraulic jacking system from falling off automatically.
3. Drum safety device: An effective measure to prevent accidents caused by improper winding of the steel wire rope beyond the drum.
4. A steel bar is welded outside the drum to restrict the wire rope to only move within the drum.
5. Fixed foundation: The digging trench is 600mm deep, concrete is poured on the lime soil, the surface is smooth, and there are waterproof and grounding protection measures.

What are the characteristics of tank welding machine?
What are the working characteristics of the tank welding machine?
What is the workflow of the tank welding machine?
In contrast to the current round welding machines on the market, the tank welding machine of the MSHW series offered by WINCOO Engineering is equipped with a dual drive system as standard. This self-propelled submerged welding system can reduce tank welding time on site by 40%. Welding errors are greatly reduced, saving tank installation costs. The circumferential welding machine is suitable for top-down or bottom-up constructions of single- or double-wall storage tanks for internal and external welding. There are four standard units, but our design allows us to offer custom mounting units for non-standard applications.
The tank welding machine belongs to fusion welding, in which a laser beam is used as energy to act on welds.
The laser beam of the tank welding machine can be guided through a flat optical element (such as a mirror), and then the beam is projected onto the weld by a reflective focusing element or mirror.
Tank welding machine is a non-contact welding process that does not need to be pressurized during operation, but an inert gas is required to prevent oxidation of the melting pool, and occasionally filler metal is used.
The tank welding machine can be combined with MIG welding to form laser MIG composite welding to achieve large-impact welding, and the heat supply is greatly reduced compared to MIG welding.
The circumferential welding equipment is a tank welding machine. The most important welding parameters in circular welding include welding current, welding torch speed, inert gas flow, etc. At the same time, the clearance fit of welded joints also plays a decisive role. Under the existing conditions, pipe ends are machined before welding lathes and repaired by fitters. In this case, the dimensional accuracy of the short ends is difficult to meet the requirements of the drawings, resulting in uneven fit gaps between the pipe ends and pipe connections; In addition, if the pipeline is displaced during staple welding, this will cause uneven spacing of the fitting surface, so that the surface of the weld is pressed in after circumferential welding. During the welding process of tank welding machine, the inside of the pipe is protected by argon gas. If there is no argon gas protection in the line, the back of the weld will be poorly formed and at the same time oxidation will occur.
Based on the availability of the customer's plant/site, WINCOO ENGINEERING CO., LTD is able to study/design and present coordinated configurations on project plan, quality, cost and productivity to ensure production pace meets project requirements.
