The following briefly introduces the application of several welded pipes (ERW, LSAW, SSAW):
1. Usually welded pipes are used for the transportation of usually lower pressure fluids such as water, gas, air, oil and heating steam.

2. Generally, carbon steel wire casing (GB3640-88) is a steel pipe used to maintain wires in electrical installations such as industrial and civil buildings, installations and equipment.
3. Straight seam electric welded pipe (YB242-63) is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on.

4. Spiral seam submerged arc welded pipe (SY5036-83) for pressure-bearing fluid transportation is made of hot-rolled steel strip coils, which are spirally formed at regular temperature and welded by double-sided submerged arc welding. The spiral is used for pressure-bearing fluid transportation. Seam the steel pipe. The steel pipe has strong pressure bearing capacity, good welding performance and safe and reliable operation. The steel pipe has a large diameter, high transportation efficiency, and can save investment in laying pipelines. Mainly used to transport oil and natural gas pipelines.

5. Spiral seam high-frequency welded pipes (SY5038-83) for conveying pressure fluids are made of hot-rolled steel strip coils, which are spirally formed at regular temperatures, and are joined by high-frequency lap welding. They are used for conveying pressure fluids. Spiral seam high frequency welded steel pipe. The steel pipe has strong pressure-bearing capacity and good plasticity, which is convenient for welding and processing. It is safe and reliable to use, with large diameter of the steel pipe, high transportation efficiency, and can save the investment of laying pipelines through various strict and scientific inspections and tests. It is mainly used to lay pipelines for transporting oil and natural gas.

6. Spiral seam submerged arc welded steel pipe (SY5037-83) for conveying low-pressure fluids is usually made of hot-rolled steel strip coils, which are spirally formed at regular temperatures, and are made of double-sided active submerged arc welding or single-sided welding. Submerged arc welded steel pipes for the transportation of low-pressure fluids such as water, gas, air, and steam.

 

Tips: Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Straight seam steel pipes can be divided into high-frequency straight seam steel pipes (ERW Pipe) and submerged arc welded straight seam steel pipes (LSAW Pipe)  according to the production process. Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development.

ASTM A53 Grade B is the material under the American steel pipe standard, API 5L Gr.B is also the American standard materialPsychology ArticlesA53 GR.B ERW refers to the electric resistance welded steel pipe of A53 GR.B; API 5L GR.B Welded refers to the material Welded steel pipe of API 5L GR.B.
