Longitudinal Submerged Arc Welded Pipe (LSAW Stainless Steel Pipe)
Longitudinal submerged arc welded pipe, also known as LSAW stainless steel pipe is processed using double-sided submerged arc welding under static conditions. Thanks to the advanced welding technology, our LSAW stainless steel pipe has small and high quality welding seams.
Used for pressure piping, our longitudinal submerged arc welded pipe is more and more widely used for the conveyance of petroleum, natural gas, and other flammable mediums. The stability of its manufacturing process increases the usability and safety of the stainless steel welded pipe.
If you are constructing a heavy steel structure or fluid pipeline, contact us. No matter your need for longitudinal submerged arc welded pipes, hot extruded pipes, or cold drawn pipes, we can provide you with what you need.
Our longitudinal submerged arc welded pipe can be designed and manufactured in accordance with the ASTM/ASME, DIN, EN, JIS, and GOST standards.
