API Line Pipes
SAWH API Line Pipe is one kind of our superior products,Website:, and it is satisfied by domestic and oversea clients. It is fabricated with superb manufacturing technique by advanced equipment imported from America. It has been exported to South East Asian, Europe, Africa, and Middle East and so on. SAWH API Line Pipe is produced by strip coil as raw material, shaped into round section with helical seam by the extrusion molding; meanwhile the seam is welded automatically in double-wire submerged arc welding process.Technical Features: A. ☆During the forming process, the steel coil is reformatted uniformly, so that the residual stress is small, the surface does not appear scratches.B. ☆ Using advanced double-sided submerged arc welding process can be in the best position for welding, is rarely appear the off side and welding misalignmentsuch non-through-welding, so the welding quality easy to be controlled.C. ☆100% quality inspection is done for each SAWH API Line Pipe. To make the whole process of steel pipe production are under effective detection, and guarantee the product quality.D. ☆All equipment of the whole production line is of the function of the computer data acquisition system networking to realize the data transmission in time, the central control room is in charge of the technical parameters for the production process.Wall Thickness:6MM-25.4mmOut Diameter:219mm-2220mmLength:1.5-24m or customizedSteel Grade:GR.
