| 摘要 |
The invention relates to a coupling construction, comprising a coupling element (1) and at least one high-pressure pipe (2), said high-pressure pipe comprising an external sheathing layer (3), a reinforcement layer (4) and an internal lining (5). Said coupling (1) comprises an internal welding sleeve (13), the external surface of which bears a helically wound heating element (7), as well as a force transfer element (8) that acts cooperatively with the reinforcement layer (4). The heating element comprises a heating wire (10) and a shell (11) encompassing the heating wire. The welding sleeve (13) and the sheathing layer (3) are fused by material originating from the welding sleeve (13), the sheathing layer (3) and from the shell (11) encompassing the heating wire. The invention also comprises a welding sleeve for use in the coupling construction, as well as a method for producing a coupling construction. |
