ABSTRACT:
A pressure-tight, rotary pipe coupling joins rotating, high temperature fluid transmission lines. Pressure seals of the coupling are maintained at a temperature lower than that of the high temperature or primary transmitted fluid by thermally insulating the seals from the high temperature fluid and by pumping a fluid coolant through annular cavities located adjacent the seals. A balanced pressure structure substantially eliminates thrust forces between the coupling members and reduces rotating friction.
