The maximum wall thickness of the LSAW steel pipe can be 50mm, the press of the pressure is limited, and if you need a steel pipe which wall thickness exceeds 50mm, seamless steel pipe can be the only choice.

The minimum wall thickness of LSAW steel pipes can be produced to 8mm. The first step is to press the plate into a round shape when produce LSAW steel pipes. Therefore, there are requirement on the wall thickness of the steel plate. If the steel plate is too thin, the press cannot crush the steel plate or it can cause deformation, or pressed into an ellipse. So that minimum wall thickness LSAW steel pipe can be produced is 8mm. The wall thickness is less than 8mm using coiled pipes. The coiled pipes are made by T-welding, which are all section by section. The stitching is different from the straight stitch.

Changsha Xiangjia Metal Materical Co., Ltd. is the leading manufacture in China, has been insisting on product quality as the center and inheriting quality for 18 years. If you need any steel pipes, we are your good choice.
