The application of JCOE PIPE with 18inch-56inch /457mm-1422mm :
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.
