LSAW PIPE

LSAW pipe

LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.
Thick walled steel pipe

Thick wall steel pipe refers to the pipe diameter and wall thickness ratio of less than 20.
