08/19/2010

Welded steel pipe, or we can call it welded steel tube.It is steel tubes welded through the curling sheet or strip.

With its simple manufacturing process, high efficiency , variety specifications and less equipment capital, however, the welded pipe is not as strong as seamless steel pipe.Since the 1930s, specifications of welded pipe have been growing.

Welded basket strainer can divided into longitudinal and spiral welded pipe according to the form of welding.

Not only longitudinal pipe's production process is Needle Valve, the efficiency is high, but it also has a low cost. So it's developing fast these days.Generally speaking, the spiral welded pipe is stonger than longitudinal pipe.

Generally, the pipe with a smaller caliber almost use straight seam welding.However, large-diameter pipe use spiral welding.
