Product introduction

 

 

 

 

Longitudinally Submerged Arc Welded (LSAW) steel pipes are a type of steel pipe that is manufactured using the submerged arc welding process. This method involves the use of an electric arc to weld the edges of a steel plate together to form a cylindrical shape. The key feature of LSAW pipes is that the welding process occurs beneath a layer of granular flux, which protects the weld from atmospheric contamination and ensures a high-quality weld.
