Straight Seam Submerged Arc Welded Steel Pipe LSAW 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.
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.
