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.

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.

What should we pay attention to before using the hydraulic storage tank lifting equipment?
What should be paid attention to during the use of hydraulic storage tank lifting equipment?
What are the steps of using hydraulic storage tank lifting equipment?
1) Before use, it is necessary to check whether all parts of the hydraulic storage tank lifting equipment are normal, mainly check whether the piston, joints, high-pressure hoses, etc. leak oil.
2) The regulations in the main parameters should be strictly followed during use, and super high overload should be avoided, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the hydraulic cylinder.
3) If the oil in the manual hydraulic pump is insufficient, it is necessary to add fully filtered hydraulic oil to the pump before it can work.
1) The choice of the center of gravity of the heavy object should be moderate, the focus point of the hydraulic storage tank lifting equipment should be selected reasonably, and the bottom surface should be flat. At the same time, the soft and hard conditions of the ground should be considered, whether it should be lined with tough wood, and whether the placement should be stable, so as to prevent the load from sinking. or inclined.
2) After the hydraulic storage tank lifting equipment lifts the heavy object, the support should be used to support the heavy object in time.
3) If several hydraulic storage tank lifting equipment need to be lifted at the same time, in addition to the correct placement of the jacks, attention should be paid to the balanced load of each hydraulic storage tank lifting equipment, and attention should be paid to keep the lifting speed synchronized to prevent the objects being lifted from tilting danger occurs.
1) When using the hydraulic storage tank lifting equipment, first place the hydraulic cylinder, and then tighten the oil drain screw on the hydraulic pump to work. To make the piston rod descend, loosen the handwheel of the manual hydraulic pump in a counterclockwise direction slightly, the hydraulic cylinder is unloaded, and the piston rod gradually descends. Otherwise, it will be dangerous to descend too fast.
2) The detached hydraulic storage tank lifting equipment adopts a spring reset structure. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the jack.
3) Due to the small lifting stroke of the jack, the rated stroke should not be exceeded during use to avoid damage to the jack.
4) The violent vibration of the hydraulic storage tank lifting equipment should be avoided during use (such as hitting the workpiece with a hammer when the hydraulic storage tank lifting equipment is loaded).
For many years, WINCOO ENGINEERING CO., LTDhas been a trustworthy supplier in the hydraulic storage tank lifting equipment area. If you choose this company, you will get the best quality products and the most intimate after-sales service.
The tank welding machine uses electrical energy to instantly convert electrical energy into heat. The tank welding machine is suitable for working in a dry environment without too many requirements. Because of its compact size, simple operation, convenient use and fast speed. Next, we will introduce the precautions of tank welding machine.

How to use a tank welding machine?
Introduction to the advantages and disadvantages of tank welding machine.
The advantages of tank welding machine after welding are widely used in various fields, especially for parts that require high strength. It can instantly connect the same metal material (also can connect dissimilar metals, but the welding method is different) permanently. After heat treatment, the weld seam has the same strength as the base material and is well sealed, which solves the problems of sealing and strength for the manufacture of storage gas and liquid containers.
However, when the tank welding machine is in use, a certain magnetic field will be generated around the welding machine. When the arc burns, radiation will be generated to the surroundings. The arc light contains infrared rays, ultraviolet rays and other light species, as well as metal vapor and smoke and other harmful substances. Adequate protective measures must be done at the time.
Welding is not suitable for high-carbon steel welding. Due to the process of crystallization, segregation and oxidation of weld metal, the welding performance of high-carbon steel is poor, and it is easy to crack after welding, resulting in hot and cold cracks. Low carbon steel has good welding performance, but the process must be handled properly. Derusting and cleaning are more cumbersome. Sometimes the weld will have defects such as slag inclusion, cracks, pores and undercuts, but proper operation will reduce the occurrence of defects.
Matters needing attention when cleaning tank welding machine.
When cleaning the tank welding machine, it is necessary to grind the inner and outer burrs of the tube end to make the tube end flush without burrs, and wipe it clean with alcohol. Manual tungsten argon arc welding is used for positioning, and the location of the positioning solder joints should not be too high, the current should not be too large, and the penetration is not allowed, the number of solder joints should not be less than 2, and the solder joint diameter should not be greater than 6mm.
If the position of the tank welding machine is not used properly, the position of the welding point will deviate from the neutral line of the welding butt surface. Due to the regular shape of the girth welding seam, the position welding point that deviates from the welding seam cannot be covered by the normal welding seam, resulting in The positioning welding spot is on the edge and outside of the welding seam, which makes the welding seam surface poorly formed.
How to use a tank welding machine?
l Check the connection
After completing the wiring of the tank welding machine, you must check each installed connector to confirm that it is well connected before starting to operate the equipment. Its contents include:
1. The line connection is correct and reasonable, and the grounding must meet the specified requirements
2. The magnetic work piece gripper shall not have attached metal particles and splashes on its contact surface;
3. The coiled welding cable should be unrolled before use to avoid overheating and insulation damage;
4. When it is necessary to alternately use different lengths of cables, insulating joints should be provided to ensure that useless lengths can be disconnected when not needed.
There must not be any leakage of cooling water, shielding gas or engine oil that affects the safety of welders.
l Work suspension
When the welding work is suspended (for example, during breaks), the output terminal of the equipment or tank welding machine must be turned off or the power supply must be cut off.
l Mobile welding machine
When you need to move the tank welding machine, you must first cut off the power supply at its input end.
l Equipment not used
The metal electrode and carbon electrode must be removed from the welding tongs when not in use to eliminate the risk of electric shock to personnel or conductive objects. The welding tongs must be placed out of contact with persons, electrical conductors, flammable objects or compressed air bottles when not in use. The welding torch of the semi-automatic welding machine must be properly placed when not in use to avoid accidental activation of the gun body switch.
All arc welding equipment must be maintained at any time and kept in a safe worki.
