Distinguish straight seam steel pipes by the outer diameterSmall-diameter straight seam steel pipes with an outer diameter between φ4.76-φ12.70 mm; small-diameter straight seam steel pipes with an outer diameter between φ13-φl14 mm; medium-diameter steel pipes with an outer diameter between φ114-φ40
1. Compared with 304 stainless steel pipe, the advantages of duplex stainless steel pipe are as follows:(1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plastic toughness required for forming. The wall thickness of storage tanks or pressur
