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.
