FIELD: building of pipeline transport.
SUBSTANCE: invention relates to polymeric reinforced pipes designed for transportation of gaseous and liquid chemically aggressive materials at gauge pressure and temperature fluctuations. Housing of coupling is made in form of polymeric material bushing with cylindrical spaces for ends of pipes to be connected, and its contains heating elements arranged from side of inner surfaces of spaces, movable reinforcement skeleton in form of net made of flexible threads of high-modulus fibers. Net is fixed in outer layer of polymeric bushing at depth not exceeding thickness of net, and threads forming the net are arranged at tilting to axis of bushing.
EFFECT: simplified technology of manufacture.
