FIELD: machine building.
SUBSTANCE: proposed method comprises plasma processing of inner sealing later inner surface, applying outer layer of composite material composed of reinforcement fibers and binder and hardening of binding composite material. Inner sealing layer represents tubular billet from polymer material. Plasma processing of tubular billet is carried out in cold plasma of abnormal glow discharge in air in flow mode at 2-10 Pa.
EFFECT: high operating properties at ease of manufacture.
