Abstract

A pipe coupling for fluid-sealed, electrically insulated coupling of two metal pipes (1, 3 and 2, 4, respectively) intended for the flow of a refrigerant fluid at high pressure and high temperature. The coupling comprises a coupling sleeve (8) of polytetrafluoroethylene and an external clamping sleeve (9) of metal. The wall thickness (t) of the coupling sleeve (8) amounts to 0,5 - 2,0 mm. The distance (d) between the two metal pipe ends is 0,5 - 2,0 mm and must not exceed twice the sleeve wall thickness (t), i.e. d <= 2t. Hereby, a good sealing effect is achieved even after long use.
