FIELD: metallurgy.
SUBSTANCE: nonconductive joint comprises two nozzles separated from pumped medium with dielectric material, adjacent ends of which are insulated from each other and connected by connecting nozzle, at the same time nozzles are arranged with bulge, on outer surface of bulge there are annular grooves arranged with buttress thread profile having smoothed edges, connecting nozzle on inner surface has dielectric gasket, inner surface of connecting nozzle, bulge part of nozzle and part of pipe outer surface are arranged with dielectric coating, length of which on nozzles is more than diametre of pipeline, and in order to connect liquid or gas flow metre, nozzle is increased by length sufficient for its operation conditions.
EFFECT: improved electrochemical protection and increased strength of nonconductive joint.
