LSAW Steel Pipe Character Summary:
Longitudinally Submerged Arc Welding (LSAW / SAWL) Pipe: the pipe is produced by double-side submerged arc welding and expanded diameter. During the production used pre-welding and then precision welding process, it is stable welding process and high quality weld.
Through the mechanical expansion for the whole pipe, the stress of internal pipe is small and evenly distributed, can effectively prevent the stress corrosion cracking, it is high accuracy dimension and easy to be welded and constructed on-site.
LSAW Steel Pipe
Used for low pressure liquid delivery, such as water, gas, and oil.
LSAW - UO(UOE),RB(RBE),JCO(JCOE)
