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

Longitudinal Submerged-Arc Welded Steel Pipe Usage: Used for low pressure liquid delivery, such as water, gas, and oil. Standard: API 5L, API 5CT, ASTM 53, EN10217, DIN 2458.
