Steel pipe knowledge
What Is LSAW Pipe? And the Choosing between UOE ,RB and JCOELongitudinal Submerged Arc Welded Pipe (LSAW) is produced from high-quality steel plate. Through different forming processes, the pipe is welded with double-sided submerged arc welding (SAW), and then mechanical expansion to ensure accurate diameterspecifications and superior stability. LSAW pipes are widely used in oil & gas transmission, offshore engineering, structural applications, and large-diameter pressure pipelines.Nov 15,2025- Is galvanized steel pipe safe for drinking water？Is galvanized steel pipe safe for drinking water？Galvanized steel pipes were widely used in water supply.But now something new materials are better than galvanized steel pips.Nov 8,2025
