With the progress of social and economic development, people's demand for resources continues to increase, from automobiles that require diesel to power plants that require petroleum. In short, oil, natural gas and other resources have become indispensable things in people's daily life, so people gradually invented pipeline transportation methods. Next, I will introduce pipeline construction equipment in detail.
Here is the content list:

What are the reasons for using pipeline construction equipment
Due to the large volume of pipeline transportation, most of the pipelines are buried underground, occupying a small area, less terrain and object constraints, and short transportation distances.
Use pipeline construction equipment for sealed transportation, safe and reliable, long-term continuous and stable operation, easy to manage, easy to maintain, and realize remote centralized monitoring.
Therefore, a large number of pipeline laying work has been carried out in various countries, and related companies specializing in pipeline construction equipment have been derived. WINCOO is a company specializing in pipeline construction equipment.
What is the specific process of pipeline construction
There are many factors that can lead to operational defects in pipeline construction, such as inadequate installation technology, long construction period or insufficient supervision. Relevant technical personnel should be careful, careful, and concentrate on research and judgment when inspecting and accepting pipeline construction equipment.
Provide feedback and resolve the issue as quickly as possible. If the existing safety quality is not reached, the target area should be immediately compensated to ensure that the pipeline construction equipment can continue to operate safely. And maintain the original economic cost.
Specific process introduction:
Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair.
What pipeline construction equipment is needed during pipeline construction
The following pipeline construction equipment is needed during pipeline construction:
l Transport anticorrosive pipe
l Pipe assembly
l Pipe assembly and welding
l Heat shrinkable sleeve (tape) bushing
With the continuous development of society, the demand for pipelines is also increasing, and the pressure on pipelines is increasing. During the installation and operation of pipeline construction equipment, welding is a basic technical job and also a vital job.
The safe and stable operation of pipeline construction equipment plays a key role in the overall pipeline operation. Therefore, increasing attention to the construction quality of pipeline construction equipment can lay a solid foundation for the normal operation of the factory!If you want to know more about high-quality pipe spool fabrication lines, you can also contact us at any time.
The tank welding machine can automatically and continuously weld the front and back of the cell according to the specified requirements. The welding band is fed and cut automatically during welding, and the battery string is received automatically after welding is completed. Welding processes include infrared lamp welding and electromagnetic high frequency induction welding.

What are the characteristics of 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.
What are the working characteristics of the tank welding machine?
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.
What is the workflow of the tank welding machine?
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.
According to the width of the steel plate, adjust the height of the operating vehicle, so that the distance between the bottom edge of the wheel and the upper surface of the tray can reach the width of the steel plate. At this time, the upper limit of the tray is adjusted in the middle position, and the beam of the tray can also be adjusted accordingly in the construction according to the situation.After adjusting the operation car, be sure to insert the puncture pin of the column and tighten the screws to ensure the smooth operation of the car during walking
2. Power access
Make sure there is no short circuit in the operation car, place the welding power switch in the correct position of automatic welding, turn on the power, and close the main switch of the welding power supply.And test and debug the system is normal operation.
3. Clean the groove
The Angle grinder is used to clean up the oil and rust in the groove, remove burrs, splashes and solder spots on the groove surface. The lower vertical joints of the steel plate are ground to 100mm, and the contact points between the upper vertical joints and the transverse joints are handled well to make the bottom of the groove smooth and smooth, so as not to hinder the movement of the pallet along the steel plate.
4. Install the welding wire
Put the wire into the wire tray for fastening, and then cut off part of the bundled string.
A hose should be added between the welding wire plate and the welding gun to avoid electric leakage between the welding wire and the body.The pressing force of the straightening wheel should be small to avoid bending of the welding wire caused by excessive pressure.After the welding wire is inserted into the gun barrel, close the wire feeding pressing wheel and press the "wire feeding" button to send the welding wire out of the conductive nozzle for a length. At this time, all the binding ropes are cut open.The pressing degree of the pressing wheel should be appropriate. If it is too loose, it will cause the wire to slip. If it is too tight, it will cause the wire indentation to be too large, and the resistance will increase, leading to the instability of the welding arc.When the conductive tip is worn too much, it must be replaced in time, otherwise the conduction is not reliable, and it is easy to cause the welding arc instability.
5. Filling flux
The flux shall be dried with a special drying box, and the heating temperature shall be as per the requirements of the flux. After heating, the flux shall be kept warm to about 50℃.When the flux temperature is too high, it can not be loaded into the flux box, so as not to burn the flux pipe.Pay attention to clean the dust on the filter cover in the flux box to ensure the suction of recovery.
6. Adjust the torch
Adjust the position and Angle of the welding torch so that it is in the center of the supporting belt.Operator requires that the stretching length of the wire is 20-30mm, that is, the distance between the conductive tip of the welding gun and the steel plate. The Angle of the welding gun is generally about 25 degrees.
7. Adjust the flux transport and recovery system
Adjust and operate the roof wheel, so that the tray is separated from the steel plate. Adjust the supporting belt on the tray to about 15-20mm below the groove, and then remove the roof wheel from the steel plate, so that the supporting belt contacts the tank wall, and test the operation for about 1M to check whether it is in normal operation.Adjust the relative position of the conveying port and the welding gun to ensure that the welding flux can fully protect the welding point;Adjust the position of the recovery port to ensure that all unreacted flux can be recovered to the flux tray.
8. Check whether the welding power switch is correct, whether the ground wire contacts and conducts well, check whether the switch behind the operation box is in the "automatic" position, and close the welding power switch.
9. Adjust the wire does not contact the steel plate, open the wire feed pressing wheel, press the "start" button of welding, at this time the voltmeter is displayed, adjust the voltage to 35V, and adjust the current to make the wire feed wheel speed is appropriate, press the "stop" button.(This work is mainly to ensure that the arc is easy to start after welding, the welding current and arc voltage are stable and the arc is normal.)
With the progress of society and the development of economy, people's demand for resources is increasing.From cars that need diesel to power plants that need oil.In short, oil, natural gas and other resources have become indispensable in daily life.But conventional rail and cruise transport is slow and uncertain.Gradually, people invented the method of pipeline transportation.
The transportation volume of pipeline transportation is large. Most of the pipeline is buried in the ground, which covers less land and is less constrained by terrain and objects, thus shortening the transportation distance.Sealed transportation, safe and reliable, long-term continuous and stable operation;Easy to manage, easy to realize remote centralized monitoring.
As a result, a large number of pipeline laying work was carried out in various countries, and thus the related companies specializing in pipeline laying work were also derived.We are specialized in providing pipeline construction equipment company.
