Joint between two preferably metallic pipes and its production process. |
| abstract |
Sealing and cracking problems arise when joining by welding large diameter pipes 1 and 2 of oil or gas pipeline; the problem is solved by using an external peripheral part 3 and a part at the joint external peripheral 4 and applying the part 4 by explosive welding; simultaneously, the external peripheral part 3 forms a solid joint, thanks to the effect of explosive welding. |
