REINFORCED PIPE ENVELOPE FOR HIGH PRESSURE Russian patent published in 2000 - IPC

Abstract RU 2147355 C1

FIELD: pipes-envelopes. SUBSTANCE: flanges of pipe-envelope are provided with elasto-flexible circular tail-pieces made integral. These tail-pieces have convex curvature and are smoothly engageable over external surfaces with circular radial recesses in bases of flanges. Inner protective coat is provided with elasto-flexible circular collars projecting inside pipe-envelope and overlapping the end faces of protective inserts mounted in central passages of flanges. Circular radial grooves of flange bases are used for receiving thin-walled elasto-flexible circular gaskets made from rubber-like matter and fixed by turns of load-bearing framework made from composite material. EFFECT: enhanced strength and reliability of pipe-envelope. 7 cl, 5 dwg
