SSAW steel pipe indicates spiral pipe, which is made of hot-rolled steel plates. When it comes to the very same steel quality and also criterion, generally cost for SSAW steel pipe is reduced than that of ERW steel pipe as well as LSAW steel pipe. SSAW steel pipe is typically used to transfer gas, oil, or water because of the largest dimension. Production Process: Spiral Submerged- Arc Welding.
