Anti-Corrosive Spiral Welded Steel Pipes 3 Layer Pe Coating Seamless Steel Pipe Corrosion Resistant Casing Series Pipes

Description

Urban construction:: various building structure pipes, bridges, docks, etc.

Structural pipes:: used as piling pipes, bridges, docks, roads, building structure pipes, etc. 

Low cost:

The production cost of welded steel pipes is lower than that of seamless steel pipes, especially in large-diameter pipes.

High efficiency:

The production process is simple, the production efficiency is high, and it is suitable for mass production. 

Can manufacture large-diameter pipes:

Compared with straight seam welded pipes, spiral welded pipes can use narrower billets to produce larger diameter pipes. 

High strength:

The strength of spiral welded pipes is generally higher than that of straight seam welded pipes, and they can bear higher pressures. 

Manufacturing method:

Double-sided submerged arc welding: Spiral welded pipes usually use double-sided submerged arc welding technology to ensure weld quality and reduce slag inclusions and pores. 

Steel strip bending: The steel strip is rolled into a spiral tube billet and then welded.
