SSAW Steel Pipe

Product details

Introduction

SSAW steel pipe, also known as spiral submerged arc welded steel pipe, is a spiral welded steel pipe produced by double-sided submerged arc welding. Spiral welded pipes are formed using narrower sheets or hot rolled coils, which greatly reduces their production costs. The spiral welding process allows the production of large diameter pipes suitable for transporting large quantities of oil and gas.

Manufacturing Process

SSAW steel pipe in the production process, we need to pay attention to a series of matters. Except for the following test items, according to the API standard and other relevant standards and the special requirements of some users, but also the need for steel, steel pipe and other tests Destructive tests, including physical and chemical properties of the raw materials into the plant sampling, visual inspection of 100% steel .

A. Oiled marking: steel after passing were oiled to prevent corrosion, and according to user requirements for marking.
B. Leveling Milling: The flat steel anvil machine so that the original curl, and then through the edge milling machine for two-sided steel milling, so as to meet the requirements of the plate width, plate edge parallelism and groove shape.
C. Shear molding: the steel plate production line along the outer edge of the spiral curl into a tube.
D. Butt cut: double-sided submerged arc welding using advanced technology to pre-welding, internal welding, outside welding. The welded steel pipe using a plasma-foot cut to specification length.
