Spiral Welded Carbon Steel Pipe For Sale
Our spiral welded carbon steel pipes are made by rolling low-carbon carbon structural steel into a pipe blank at a specific spiral angle, and then welding the pipe seams. This process allows us to produce large diameter steel pipes, which is very beneficial to various industries. By utilizing narrow steel strips, we can create pipes with superior strength and durability.

Hydrostatic Test
The pipe shall withstand the hydrostatic test without leakage through the weld seam or the pipe body
Jointers need not be hydrostatically tested, providedthat the portions of pipe used in marking the jointers were successfully hydrostatically tested prior to the joining operation.
