METHOD OF CONNECTING PIPES WITH POLYMERIC COATING BY CRIMPING COUPLING

摘要

FIELD: mechanics. ^ SUBSTANCE: in the connection on the middle part of inner bush there installed is a rubber gland of T-shaped rectangular section that at the same time is both restricting and sealing. On the ends of inner bush there installed are rubber sealing rings, and to polymeric coating there applied is adhesive composition that, during crimping of outer coupling, forms an adhesive bead on the ends of inner bush and also forms reliable sealing of the joint of the pipes being connected. ^ EFFECT: invention increases reliability of the joint's sealing of the pipes being connected. ^ 1 dwg
