ERW Steel Pipe (electric resistance welding) is produced by welding strip of flat sheet metals.
That are formed, bent and prepared for welding. After that, making galvanization treatment to help prevent corrosion, rust, thereby extending the pipe life.
Welded carbon steel pipes is available in A53, BS1387 and API 5L specification. Welded carbons steel is the most cost effective solution for a high quality pipe with pressure integrity test.

ERW Pipe Galvanized FAQs
What Is The Difference Between LSAW Pipe And ERW Pipe?
The LSAW pipe diameter range is larger than ERW, normally from 16 inch to 60 inch, 406mm to 1500mm. Good performances on high pressure resistance, and low-temperature corrosion resistance same as well.
