Berg Pipe SAWH Manufacturing Process

Berg Pipe Mobile has specialized and optimized the two-step Submerged-Arc Helical Welding (SAWH) manufacturing process. The strip is pushed through a three-roll bending stand and formed into a spiral, with the two edges of the strip meeting after the forming process. Pipe is welded on one of three welding stands using a three-wire

SAWH - Product And Service PANYU CHU KONG STEEL

SAWH - Product And Service PANYU CHU KONG STEEL PIPE CO.,LTD. This production line adopts the most advanced welding process technology, namely Two Step Production Process. The pipes are firstly formed into a pipe body and continuous tack-welded at high speed. In the second process step the pipes are subsequently finally submerged arc welded SSAW Steel PipeThreeway steel has overwhelming advantages over cometiotors in manufacturing this SAWH steel pipe.We have 10 traditional one-step production lines and 1 two-step production line that enabels to produce finely pre-welded SAWH steel pipe of 360000 tons per year,and we have become the leading enterprise in this industry in virtue of large productivity and advanced technical equipment.

Spiral Welded Pipe Manufacturing Process - Permanent Steel

Sep 14, 2020 · Spiral welded pipe (SSAW/SAWH):a low carbon carbon structural steel or low alloy structural steel strip is rolled into a tube blank at a certain spiral angle (forming angle), and then the tube seam is welded together. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are eed by outer diameter * wall thickness, and the welded pipe shall be ensured that the hydraulic test, the tensile strength of the weld THE LINCOLN ELECTRIC COMPANYU.S. Steel, SeAH and POSCO, uses an advanced auto-mated two-step welding process that is capable of producing 300,000 net tons of line pipe per year. Outside diameters of produced spiral pipe range from 24 to 64 inches, using A252- through X80-grade steel with wall thicknesses from ¼ to 1 inch. The process consists of one forming and three
