LSAW Pipe Manufacturing Process

Winsteel Group as a professional lsaw pipe welding factory, we have got API 5L & ISO certificate for more than decade years. Welded Pipes made by lsaw pipe mill are using steel plate as raw material. Let’s see lsaw pipe manufacturing process, first, plate is rolled in the circular section with the help of plate bending machine.

What is LSAW Pipe?

LSAW is short for Longitudinally Submerged Arc Welding steel pipe. And these 5 aspects will help you recognize what is lsaw pipe. I will clarify from the aspect: raw material of lsaw pipe, weld seam, lsaw pipe size range, welding method, and length of lsaw pipe. From this five aspects, you will know the characters of lsaw pipe in these simple way.

Differences Between ERW and HFW Steel Pipe

ERW steel pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.
