Supply & Demand

Our company uses the most advanced technology of JCOE LSAW steel pipe manufacture in the world wide， specialized in producing heavy calibre LSAW steel pipe. The product line adopts PID automatic controlling continuous J-C-O forming technology, and the advantages of the product line are as below: high speed, high quality, low stress distribution, and low tolerance of size. The equipment can change mould quickly and simply, produce wide range of specifications, which is specialized in producing Longitudinal Submerged Arc welding Pipeline of outside diameter from 406.4mm to 1422.4mm ,wall thickness from 6m to 50m,unit length from 3m to 12.5m,steel grade could be simple carbon steel, special type steel and low alloy steel ,the steel grade could be up to max X80 .

The company introduces internationally advanced JCOE production technology, and all production equipment is produced by domestic first-class manufacturers. It specializes in producing large diameter straight seam double-sided submerged arc welded steel pipes with a diameter of 457.2-1422.4mm, a wall thickness of 8mm 50mm, and a length of 5.8m 12.5m. The materials are ordinary carbon, special steel, and alloy steel, with the highest steel grade reaching X80. The production line adopts the full line PID automation control continuous J-C-O molding process, which is fast, high-quality, with uniform distribution of molding stress, regular tube shape, and an annual output of 150000 tons.
