European Piling Pipe

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 .it is able to manufacture 150,000 tons per year.

1. The welding: the columns more wire submerged arc welding wire (up to 4) in the straight seam welded steel pipe inside;

2. The welding: adopting many wire submerged arc welding of columns in the side of straight seam submerged arc welding steel pipe welding;

3. Ultrasonic inspection Ⅰ: inside and outside of straight seam welded steel pipe weld and weld on both sides of the base of 100% of the check;

4. X-ray Ⅰ: 100% of inside and outside weld X-ray industrial TV inspection, using image processing system to ensure the sensitivity of detection;

5. Hole enlargement of submerged arc welding and straight seam steel pipe length hole diameter in order to improve the size precision of steel tube, and improve the distribution of stress in steel tube.
