Introduction of welded steel pipe-erw-ssaw-lsaw. ERW welded steel pipe:High frequency electric resistance welded pipe, raw material is hot rolled steel plate, through the continuous forming, bending, welding, heat treatment, sizing, straightening, cutting process.

LSAW Steel Pipe Production Line JianHe Steel

Jianhe Steel has a state-of-the-art production line for LSAW steel pipes. This line uses a YSD forming machine that features a high forming precision, excellent forming speed, uniform stress distribution and small residual stress. The main equipment, such as the pre-springing equipment, is supplied by the Tianshui Metalforming Machine Tool Group. The straight seam welded pipe line uses large power, CO2 gas shielded, pre-welding technology and DC/AC automatic submerged arc welding machines LSAW Steel Pipe23 rows · LSAW Steel Pipe.

Longitudinal Submerged Arc Welding (LSAW) Processes

In LSAW pipe mills, processing is carried out by cold forming heavy carbon steel plates, the pipe prematerial on which many of the pipe properties depend. The material of LSAW steel pipe is unit middle or heavy thickness sheet, coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter. Longitudinally Submerged Arc Welded Steel pipes, 8 rows · LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe
