Welded steel pipe Longitudinal welded pipe Spiral welded pipe
LSAW ERW EFW
Welded steel pipe refers to a steel pipe with seams on the surface that is welded after bending and deforming a steel strip or steel plate into a circular, square, etc. shape. The blank used for the welded steel pipe is steel plate or strip steel.

Coiled pipe is committed to producing all kinds of coiled pipes and steel pressure steel pipes of circular seam and longitudinal ring, and is transformed on the basis of the same specifications and models of traditional pipe coiling equipment. The function of increasing the parameters of the coiling equipment by 30% fills the gap that the original traditional coiling equipment cannot produce. It can produce steel pipes with a diameter of more than 400mm and a wall thickness of 8-100mm.
