Abstract
A coupling for interconnecting at least two pipes (1) of a geothermal heat exchanger system, including at least one female coupling part (2) and at least one male coupling part (3) that can be inserted therein, with at least one fluid seal (4) being provided between the coupling parts (2, 3) for sealing the coupling parts (2, 3), especially in a fluid-tight manner. At least one, preferably annular or cylindrical, reinforcing element (5) supports at least one of the two coupling parts (2, 3), preferably at least the female coupling part (2), so that the coupling part (2, 3) is not radially deformed, preferably not radially expanded, and is produced of a material or material composition different from that of the coupling part (2, 3).
Claims27
A coupling for connecting at least two pipes of a geothermal heat exchanger system comprising at least one female coupling part and at least one male coupling part that can be inserted therein, at least one fluid seal is provided between the at least one female and the at least one male coupling parts to seal the coupling parts, at least one sheath-shaped reinforcement body reinforces at least the at least one female coupling part against a radial expansion of said female coupling part and is formed from a different material or a different material composition than said female coupling part, wherein the coupling further comprises a locking socket, which in an assembled state of the coupling encloses a connection area between the female coupling part and the male coupling part.
