LSAW Q235 welded spiral steel pipe for manufacturing

What is The Differences Between LSAW Pipe and SSAW Pipe

It is using the same welding technology of Submerged Arc Welding with LSAW pipe. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a China GB Q195 Q235 Q345 SSAW Spiral Welded Steel Pipe LSAW Carbon Steel Pipe, LSAW Pipe, LSAW Steel Pipe manufacturer / supplier in China, offering GB Q195 Q235 Q345 SSAW Spiral Welded Steel Pipe for Oil and Gas Manufacturing, 3 Inch 1 Inch A182 Gr.

Introduction to Welded Pipe Manufacturing The Process

Jul 26, 2018· The LSAW pipe diameter range is larger than ERW, normally from 16 inch (406mm) to 60 inch (1500mm). Good performances on high pressure resistance, and low temperature corrosion resistance. Spiral Submerged Arc Welding (SSAW) Process. In Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, welding line shape like a helix.Differences Between SAW and ERW Pipe Winsteel GroupIn manufacturing processes, we can see SAW pipes (LSAW, SSAW) and ERW pipes are entirely different right from the formation and welding method, etc. SAW Welded Steel Pipe Manufacturing ProcessIn a single seam SAW steel pipe, the wedding is done with the help of the submerged arc welding process.Types of Oil & Gas PipesSeamless, ERW, LSAW An LSAW pipe (submerged arc welding) is manufactured by cutting, bending and welding steel plates (JCOE process). LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches but are must go option for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).

Difference between ERW, SSAW, LSAW Sunny Steel

Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small diameter high pressure natural gas pipeline, used for a small number of long distance gas pipeline, the vast majority of long distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).L235 EN10224 ERW welded steel pipe/spiral steel tubesERW welded steel pipe is used for liquid deivery which has low pressure water, gas, and oil Oil drilling and machinery manufacturing,21.3 813mm 2.11 59.54mm L235 EN10224 ERW welded steel pipe/spiral steel tubesLSAW pipes Production Range sunnysteelLSAW pipes Production Range .
