FIELD: mechanical engineering.
SUBSTANCE: pipe coupling wall design contains a fibred external plastic layer in which fibres extend mainly in an axial direction of the coupling, a fibred internal plastic layer enclosed by the ends of the external layer and comprising the fibres extending mainly in a circle direction of the coupling, and a monolithic sealing made of a deformable material and designed so that a piped fluid does not contact with a connecting material of the coupling.
EFFECT: invention provides higher reliability of the connection.
