ERW Steel Pipe
High-frequency welded pipes are generally straight-slit , but straight-slit welded steel pipes are not necessarily high-frequency welded.

The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the

high-frequency current after the hot-rolled coil plate is formed by the molding machine, and the edge of the tube blank is heated and

melted , and pressure welding is performed under the action of the pressing roller to realize the production . The high-frequency resistance

welded steel pipe is different from the ordinary welded pipe welding process . The weld is made of the base material of the steel strip body ,

and the mechanical strength is better than that of the general welded pipe. The surface is smooth , high precision , low cost , and has low

weld seam height , which is beneficial to the coating of 3PE anti-corrosion coating .

Application of Welded Steel Pipe
Welded steel pipes are commonly used in a wide range of applications and industries, including:

1. Water and wastewater transportation: Welded steel pipes are used to carry water, sewage, and other fluids in municipal and industrial plumbing systems.

2. Oil and gas pipelines: Welded steel pipes are utilized in the construction of pipelines for the transportation of oil, natural gas, and other hydrocarbons.

3. Structural applications: They are used in the construction of buildings, bridges, and other structures as structural support elements.

4. Automotive and transportation: Welded steel pipes are used in the manufacturing of automobile exhaust systems and chassis components.

5. Manufacturing and industrial processes: They are used in various manufacturing and industrial applications, including conveying materials and gases within factories.

6. Agriculture: Welded steel pipes are used for irrigation systems, drainage, and other agricultural applications.

Process of ERW Steel Pipe


Packing

1. Plastic caps plugged at the two sides of pipe ends
2. Should be avoided by the steel strapping and transport damage
3. Bundled signs should be uniform and consistent
4. The same bundle(batch) of steel pipe should be came from the same furnace.
5. The steel pipe has the same furnace number, the same steel grade, the same specifications.
