Product Description

Straight seam pipe is a Steel Pipe, weld steel pipe means parallel to the Longitudinal Pipe. Classified by the wall thickness of thin-walled and thick-walled straight seam pipe straight seam pipe; according to shape classification round pipe, square shaped tube or pipe; there are generally classified by use pipe, galvanized pipe, oxygen blowing pipe, wire casing, metric pipe, roller tube, deep well pump tube, automotive tube, transformer tube, welding thin-walled tube, welding shaped tube and spiral welded pipe.

Product classification
According to weld shape classification: Can be divided into straight seam welded pipe and spiral welded pipe
ERW: simple production process, high production efficiency, low cost, rapid development.
Spiral welded pipe: intensity is generally better than straight seam welded pipe is high, can use a narrow diameter of billet production larger pipe can also differ with the same width of the billet production diameter pipe. But with the same length of Straight Pipe, weld length of 30~100%, and the production rate is low. Therefore, most of the small caliber pipe welded, large diameter welded pipe mostly using spiral welding.
