The Difference Between Seamless Steel Pipe and Welded Steel Pipe
The seamless steel pipe is made of high-quality carbon steel or alloy steel, which can be divided into hot-rolled and cold-rolled (drawn).
Welded steel pipes are formed by welding steel plates into a tube shape with straight seams or spiral seams. In terms of manufacturing methods, they are divided into LSAW, SSAW, and ERW etc.
Seamless steel pipes can be used for liquid pneumatic pipelines and gas pipelines in various industries
Welded pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes, etc.
Welded steel pipes are divided into furnace welded pipes, electric resistance welded (ERW) pipes and automatic arc welded pipes due to their different welding processes. Due to their different welding forms, they are divided into two types: straight seam welded pipes and spiral welded pipes. Because of their end shapes, they are divided into round Shaped welded pipe and special-shaped (square flat) welded pipe.
