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.
Tank welding machines are actually transformers with lower external characteristics, which convert 220V and 380V alternating current into low-voltage direct current. Electric welding machines can generally be divided into two types according to the output power source. Therefore, tank welding machines can be divided into many types according to different characteristics.
Here is the content list:
l Tank welding machines are classified according to power characteristics.
l What types of tank welding machines does WINCOO have?
l What are the classifications of tank welding machines based on the market industry?
One type of tank welding machine is AC power and the other is DC power. A DC welding machine can be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer, and then rectified by the rectifier, and then outputs a power source with reduced external characteristics.
The output terminal will produce huge voltage changes when it is switched on and off the tank welding machines. When the two poles are short-circuited momentarily, the arc is ignited, and the generated arc is used to melt the electrode and welding material, and after cooling, the purpose of combining them is achieved. Welding transformers have their own characteristics. The external characteristic is the sharp drop in voltage after the electrode is ignited.
WINCOO provides automatic tank welding machines for tank manufacturing applications. Unlike other tank welding machines on the market, WINCOO AGW comes standard with a dual drive system and other features unique to our machines.
This automatic submerged arc welding system can reduce on-site tank welding time by 40% and reduce welding defects by increasing the arc on time. These models run directly on the fuel tank and carry the operator, eliminating the need for scaffolding, while ensuring the comfort and safety of the operator.
Due to the modular design, tank welding machines are suitable for single-wall or double-wall storage tanks constructed from top-down or bottom-up. Our design allows us to provide customized units for special applications.
EGW vertical gas-electric tank welding machines are highly efficient automatic welding equipment, which can control the improvement of the welding frame according to the current feedback closed loop. In a water-cooled forced welding seam, the main feature of a forming is the thickness from 10mm to 50mm.
The liquid level of the molten pool is automatically controlled, and the wire length is automatically adjusted. Small size, light weight welding frame and easy to update flexible modularization, easy to use. Widely used in petroleum, chemical, blast furnace thick plate welding and shipbuilding industries.

The plasma and flame cutting machine is a portable multifunctional plasma welding, cutting, high energy flame heating equipment.
What are the precautions for the use of plasma and flame cutting machine?
Compared with similar products, what are the characteristics of plasma and flame cutting machine?
What are the advantages of plasma and flame cutting machine?
1. Points to be paid attention to in forging cutting
Due to the thicker oxide scale on the surface of the forging and the fact that the ignition point of the oxide scale is higher than the melting point, the plasma and flame cutting machine is prone to cutting interruption during cutting, resulting in reduced cutting quality and reduced work efficiency. For this reason, when the forging is cut, the oxide scale on the upper and lower surfaces of the cutting area should be removed before cutting to improve the cutting speed and cutting quality.
2. The main points of anti-deformation in rolling billet cooling bed tooth plate cutting
How to control the deformation of the workpiece during cutting is very important. For example, arranging the cutting route according to the routine will cause the workpiece to be deformed and out of tolerance. Even if it is reshaped, it is difficult to meet the size requirements, and the product will eventually be scrapped. Therefore, it is very important to arrange the gas cutting route of the plasma and flame cutting machine reasonably.
3. Points to be paid attention to in thick plate cutting
In thick steel plate cutting, the temperature decreases from the top surface down. At the beginning of cutting by plasma and flame cutting machine, the oxygen pressure is gradually increased, and finally reaches a uniformity in the thickness direction of the steel plate. This results in inconsistent combustion in the thickness direction of the steel plate at the starting position of cutting, and defects at the starting end of the workpiece cutting.
Compared with laser cutting: plasma and flame cutting machine is far less than laser cutting machine in terms of cutting speed accuracy and cutting material types, but it is better than laser cutting machine in cutting thickness and cutting cost.
Compared with high-pressure water jet cutting machine: the precision of high-pressure water jet cutting machine and the types of cutting materials are better than plasma and flame cutting machine, but plasma and flame cutting machine are larger than water jet cutting machine in cutting speed and cutting thickness, and the equipment The cost and cutting cost are relatively low.
The plasma and flame cutting machine can be used for drawing, programming, nesting, verification and CNC cutting of any shape parts. Improve the steel nesting rate, effectively save steel; improve the efficiency of programming, nesting and cutting, and effectively improve the cutting production efficiency.
Great products begin with the best engineering staff, and WINCOO ENGINEERING is ready to assist you with your technical requirements for plasma and flame cutting machine.
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!
