Huaxi Steel - Model LSAW -Steel Pipe
Straight seam submerged arc welded pipe (LSAW) is a welded steel pipe manufactured by submerged arc welding (SAW) process, and the weld direction is parallel to the axis of the steel pipe (i.e. longitudinal welding). The process forms a high-strength and high-sealing steel pipe by pre-bending the steel plate into a tube shape and then automatically submerging arc welding under the protection of the flux layer. Huaxi Steel LSAW pipe has made many breakthroughs in ultra-thick wall and ultra-large diameter, and is very competitive in the Chinese market.
