LSAW Steel Pipes

LSAW Steel Pipe (Longitudinally Submerged Arc Welding Pipe) , DSAW Steel Pipe

Straight Seam Submerged Arc Welded Steel Pipe

LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diameter.

UOE LSAW pipe forming process:

The three main forming processes of UOE LSAW steel pipe forming process include: steel plate pre-bending, U forming and O forming. Each process adopts a dedicated forming press to complete the three processes of pre-bending the edge of the steel plate, U forming and O forming in sequence to deform the steel plate into a circular tube.

JCOE LSAW pipe forming process:

Forming: After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, then the other half of the steel plate is pressed into a "J" to form a "C" shape, and finally pressurized from the middle to form An open "O"-shaped tube blank is formed.
