  • Method of effecting a single joint between two pipes
    Patent number: 4953775
    Abstract: The invention relates to a method of effecting a single joint between two pipes of the pipe-line type by means of explosion welding, without the pipes being displaced in axial direction. This is achieved by moving an inner peripheral body (9) for welding between the pipe sections, to the joining point with the aid of a displacement unit expandable in axial direction.

  • Means for splicing two pipes
    Patent number: 4641775
    Abstract: Explosion welding is used for splicing thick pipes (1 and 2) or the transport of oil and gas. A plating ring (4) and its explosive (7) are located inside the pipes, and a support (12 and 13) surrounding the two pipes (1 and 2) in order to limit the deformation occurring in the pipes (1 and 2) during the actual welding process. Since the pipes (1 and 2) are deformed, the support (12 and 13) will also be deformed. To enable repeated used of the support (12 and 13), the section (20) thereof which is subjected to the deformation is replaced by an elastomeric material.
