FIELD: construction.
SUBSTANCE: pipeline insulating compound comprises two metal pipes with adjacent ends isolated from each other by a non-conducting washer and connected by an inner dielectric connecting pipe and an outer coupling made of composite material. The pipe-connecting outer coupling is made of a three layer composite with different winding angles, first - internal, with transverse winding turn to turn with a step equal to the diameter of the wound composite material filament, second - intermediate, with winding angle between 40-50 degrees to the axis, third - external, with winding angle between 10-20 degrees to the pipe axis.
EFFECT: increased strength and reliability of connection.
