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.

How to deal with solder balls at the arc end of tank welding machine?
What are the precautions for the use of tank welding machine?
What are the working steps of tank welding machine?
1. Welding offset
It may be that the welding position is not correct or there is a problem with the welding torch. At this time, it is necessary to consider whether the TCP (the position of the center point of the welding torch) is accurate and adjust it. If this happens frequently, check the zero position of each axis of the robot and re-calibrate to correct it.
The welding parameters may be improperly selected, the angle of the welding torch or the position of the welding torch may be incorrect, and the power can be adjusted appropriately to change the welding parameters, adjust the posture of the welding torch and the relative position of the welding torch and the workpiece.
It may be that the gas protection is poor, the primer of the workpiece is too thick or the protective gas is not dry enough, and it can be dealt with by adjusting accordingly.
4. Too much splash
It may be due to improper selection of welding parameters, gas composition or too long wire extension. We can adjust the power to change the welding parameters, adjust the gas proportioning instrument to adjust the gas mixture ratio, and adjust the relative position of the welding torch and the workpiece.
5. An arc crater is formed after cooling at the end of the weld
Add the submerged arc crater function in the work step during programming, which can be filled.
When using the tank welding machine to weld the root of the weld, start welding at the lower edge of the spot-fixed weld. Welding arc ignition by scratching method. Don't rush to weld. After the arc is ignited, preheat the starting point of the weld. The preheating has two purposes: one is to avoid the low temperature of the spot-fixed weld at the starting point and the small current used for the welding current, and the sticking phenomenon occurs, resulting in pores and leaving defects in the quality of the weld. If it is welded directly, when it is welded to the upper end joint of the spot-welding seam, the temperature of the welding seam is low, and the temperature of the welding pool cannot reach the temperature state of normal welding, which will lead to the phenomenon of impermeability or poor fusion of the welded joint, which will affect the Weld quality.
The strip material is introduced into the tank welding machine through the feeding machine, and the strip material is extruded and formed through the roller, and then arc welded with mixed gas shielded welding, rounded, output the pipe of the required length, cut by the cutter mechanism, and then straightened Straighten the machine. Spot welding machines are used for spot welding connections between tape heads. Tank welding machine is a comprehensive set of equipment that continuously welds strips into tubes, rounds and straightens them.

Hydraulic storage tank lifting equipment consists of oil chamber, oil pump, oil storage chamber, piston, crank handle, oil valve and other main parts. When working, as long as the crank handle is moved back and forth, the manual oil pump continuously presses oil into the oil cylinder. Due to the continuous increase of the oil pressure in the oil cylinder, the piston and the weight on the piston are forced to move upward together.
What are the precautions for the use of hydraulic storage tank lifting equipment?
What are the structural parts of hydraulic storage tank lifting equipment?
What should be paid attention to before using hydraulic storage tank lifting equipment?
1. Hydraulic jacks cannot be used as permanent support equipment. For long-term support, the support part should be added under the heavy object to ensure that the hydraulic jack is not damaged.
2. If only one hydraulic storage tank lifting equipment is used to lift one end of the heavy object, the hydraulic storage tank lifting equipment should be placed on the symmetrical axis of the heavy object, and the long direction of the hydraulic jack base and the easy toppling of the heavy object should be made. the same direction. If two hydraulic jacks are used at one end of the heavy object, the direction of the base should be slightly symmetrical and placed on both sides of the symmetrical axis of the heavy object.
3. When two or more hydraulic storage tank lifting equipment are used to lift at the same time, they must be commanded, coordinated, and lifted at the same time.
4. Hydraulic storage tank lifting equipment should be stored in a dry and dust-free place. It is not suitable for use in workplaces with acid, alkali and corrosive gases, and it should not be placed outdoors in the sun and rain!
The hydraulic storage tank lifting equipment is a piston type lifting equipment, consisting of a hydraulic control cabinet (pumping station), the main bearing of the high-pressure oil pipe, the accessories of the hydraulic pump system, the oil control valve, the piston jack, the ring wire rope hanger, and the pumping station by two independent Composed of a hydraulic lifting unit and a centralized electrical control cabinet, it can serve the lifting of two 10000m³ tanks at the same time. Each 10000m³ tank is equipped with 20 jacks. The total composition of the hydraulic oil pipe is distributed in two stages, and then the hydraulic oil is sent to the hydraulic jack. Short construction period, low cost and good economic benefits are its significant advantages.
1. Before lifting, put the slotted end of the handle into the oil return valve stem, and tighten the oil return valve stem clockwise.
2. The handle of hydraulic storage tank lifting equipment is inserted into the handle hole and pressed up and down, and the piston rod will rise steadily to lift the heavy object. Due to the limiting device in the jack, it will not rise when it reaches a certain height.
3. To lower the piston of hydraulic storage tank lifting equipment, just use the slotted end of the handle to slightly loosen the oil return valve rod counterclockwise (no more than 2 turns), and the piston rod will gradually descend. If there is a load, the oil return valve stem should not rotate too fast, otherwise it will be dangerous if the descending speed is too large.

What are the advantages of the basic structure of pipeline construction equipment?
The pipeline construction equipment mainly consists of pipe fittings, valves, measuring instruments, supports and hangers, etc., which are connected with the gathering and transportation pipelines through production equipment to form the entire gathering and transportation system to complete the transportation of oilfield production media.
There are many types of pipe fittings used in pipeline construction equipment, mainly low-alloy steel, low-carbon steel, etc. According to the different pressures of gathering and transportation pipelines, they are divided into low-pressure, medium-pressure, and high-pressure pipelines. When selecting the material of the pipeline construction equipment, it must meet the design requirements, and no heavy skin shrinkage should occur. At the same time, the threads and grooves of the pipe fittings must meet the requirements of use during processing.
What are the advantages of pipeline construction equipment construction technology?
Under normal circumstances, groundwater or various sulfides will have a certain corrosive effect on pipeline construction equipment during operation. Therefore, to ensure the safety of pipeline construction equipment, it is necessary to strictly control the materials of gathering pipeline equipment. Corresponding anti-corrosion measures shall be taken in pipeline construction equipment according to the actual situation.
After our actual investigation of the ground and site soil conditions, we have correctly inferred the corrosivity, and formulated scientific and reasonable anti-corrosion measures based on the analysis results, and used the correct anti-corrosion technology. At present, the anti-corrosion material often used in pipeline construction equipment is asphalt. The application of asphalt in pipeline construction equipment anti-corrosion has the characteristics of low cost, good effect and large application area.
