The next briefly introduces the use of several welded pipes (ERW, LSAW, SSAW):
1. Usually welded pipes can be used for the transportation of usually lower pressure fluids for example water, gas, air, oil and heating steam.
2. Generally, carbon steel wire casing (GB3640-88) is really a steel pipe accustomed to maintain wires in electrical installations for example industrial and civil structures, installations and equipment.
3. Straight seam electric welded pipe (YB242-63) is really a steel pipe whose weld seam is parallel towards the longitudinal direction from the steel pipe. Usually split into metric electric welded pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so forth.
4. Spiral seam submerged arc welded pipe (SY5036-83) for pressure-bearing fluid transportation consists of hot-folded steel strip coils, that are spirally created at regular temperature and welded by double-sided submerged arc welding. The spiral can be 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 includes a large diameter, high transportation efficiency, and may save purchase of lounging pipelines. Mainly accustomed to transport oil and gas pipelines.
5. Spiral seam high-frequency welded pipes (SY5038-83) for conveying pressure fluids are constructed with hot-folded steel strip coils, that are spirally created at regular temperatures, and therefore are became a member of by high-frequency lap welding. They are utilised for conveying pressure fluids. Spiral seam high frequency welded steel pipe. The steel pipe has strong pressure-bearing capacity and good plasticity, that is convenient for welding and processing. It’s safe and reliable to make use of, with large diameter from the steel pipe, high transportation efficiency, and may save an investment of lounging pipelines through various strict and scientific inspections and tests. It’s mainly accustomed to lay pipelines for transporting oil and gas.
6. Spiral seam submerged arc welded steel pipe (SY5037-83) for conveying low-pressure fluids is generally made from hot-folded steel strip coils, that are spirally created at regular temperatures, and are constructed with double-sided active submerged arc welding or single-sided welding. Submerged arc welded steel pipes for that transportation of low-pressure fluids for example water, gas, air, and steam.
Tips: Straight seam steel pipe is really a steel pipe whose weld seam is parallel towards the longitudinal direction from the steel pipe. Straight seam steel pipes could be split into high-frequency straight seam steel pipes (ERW Pipe) and submerged arc welded straight seam steel pipes (LSAW Pipe) based on the production process. Straight seam welded pipe has simple production process, high production efficiency, inexpensive and rapid development.
ASTM A53 Grade B may be the material underneath the American steel pipe standard, API 5L Gr.B can also be the American standard material , A53 GR.B ERW refers back to the electric resistance welded steel pipe of A53 GR.B API 5L GR.B Welded refers back to the material Welded steel pipe of API 5L GR.B.
