REINFORCED TUBE-ENVELOPE FOR HIGH PRESSURE Russian patent published in 1998 - IPC

Abstract RU 2113648 C1

FIELD: tubes-envelopes made from polymer composite materials. SUBSTANCE: strakes-frames of tube are provided with single radial circular projections which are engageable with them; these projections are concentrically located relative to radial meridional constructions of tube-envelope forming inclined profiled circular clearances between them. Gaskets have bulges received by circular clearances and made integral from elastic-flexible material, such as rubber; they are secured with strakes-frames and tube-envelope over respective congruent surfaces. EFFECT: enhanced reliability. 4 dwg
