FIELD: joints of pipes-envelopes made from composite material and fitted with metal tubular parts, mainly nondetachable parts mounted at their ends; transportation of liquid or gaseous media in high-pressure casings and bottles. SUBSTANCE: permanent joint includes pipe made from composite material, metal tubular part with outer pointed members and thin-walled terminal band faces with protective envelope. Pipe may be made of base of spirally wound crossing glass fibers and polymer binder. Band is made integral with tubular part. Circular adapters of band are axially shifted. Protective envelope is made in form of ring embraced by elastoflexible material; this ring narrows in thickness towards inner surface. EFFECT: enhanced strength, reliability and tightness of permanent joint. 5 cl, 6 dwg
