    Sealing and cracking problems occur when joining coarse-caliber pipes (1 and 2) for oil or gas, for instance, by means of welding. The problem is solved by using an outer peripheral part (3) and an inner peripheral part (4) at the joint, and applying the latter part (4) by means of explosive welding. At the same time, the outer peripheral part (3) forms a firm joint, due to the action of the explosive welding.

    专利说明:

    The invention relates to welding technology and can be used to connect tubular parts.
    The purpose of the invention is to improve the quality of the compound.
    Figure 1 shows the welding scheme; Fig. 2 is a diagram of a cylindrical charge.
    The method is carried out as follows.
    An outer connecting sleeve 3 is put on the joined ends of pipes 1 and 2. Inside the pipes, a connecting element 4 is placed and a cylindrical charge 5 of explosive located inside the element and connected to a disk 6 of explosive equipped with a detonator 1 is initiated (FIG. one). In this case, the sleeve 3 and the element 4 are connected by rods (not shown).
    The connecting element 4 has a triangular cross section with the apex facing the junction of the pipes 1 and 2. Moreover, the distance between the surface of the element 4 and the inner surface of the pipes
    1 and 2 increase with increasing pipe wall thickness.
    Cylindrical charge 5 may consist; At least three concentric cylindrical layers 8-10 and intermediate layers 11 and 12 of inert material (figure 2). As an inert material, you can use cardboard, wood fiber, rubber, wood, salt.
    Upon initiation of charge 5, the sleeve 3 collides with pipes 1 and 2 and the connecting element and welds them.
    Example. Two pipes of material X - 60 AP 1 are interconnected. The external diameter of the pipes is 400 mm and the internal diameter is 300 mm. A ring of material 1312 S1S with an outer diameter of 450 mm and an inner diameter of 403 mm is put on the ends to be joined. Ring length 550 mm. Inside the pipe, a ring with a triangular cross section with a height of .17 mm and a width of 155 mm is installed, inside which there is an annular charge of explosive from dynamite, which is initiated by pyrozapalom.
