FIELD: machine building.
SUBSTANCE: invention relates to field of mechanical protection and waterproofing of fixed butt connection by means of its coating by waterproof protective envelope, implemented at building of different objects. Walls of pipe of clutch is implemented from polyethylene, passing with the purpose of creation of shape memory effect (diametre) and enhancement of thermomechanical behavior- radiative molecular joining, advanced by thermocontracting edges and depressed in central (usually non-settle) part, in which it is required allow ability of heat sealing embedding of technological (for instance, resin) openings.
EFFECT: reduction of quantity of work done and reliability growth and quality of hydraulic seal of abutment joint.
