Precautions for spiral steel pipe stacking
Spiral pipe (SSAW) is a spiral seam carbon steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in water supply engineering, petrochemical, chemical, electric power, agricultur...Read more -
Production process of carbon steel welded pipe
Carbon steel welded pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). The carbon steel welded pipes produced by these three processes have their own positioning in the application f...Read more -
