Tube for transporting high-viscosity materials

A transport pipe for high viscosity materials, comprising:

• an inner pipe (10) made of an abrasion-resistant plastic,
• at least one joint element (12) materially joined to an external end of the inner pipe (10), which includes a radially extending collar (16) and a ring sleeve concentric to the inner pipe (10) extending axially from one side thereof, as well as
• a reinforcing jacket (14) which envelops at least the internal pipe and is connected thereto and to the joint element (12), wherein the reinforcing jacket (14) is formed by a fiber structure impregnated in a plastic matrix, and wherein the fiber structure includes axially laid cross plies and/or radially laid circumferential plies or tiers,
• wherein the ring sleeve (18) of the joint element exhibits an outer surface (34) with outer diameter varying in the axial direction,
• wherein the reinforcing jacket (14) is formed by a fiber structure impregnated in a plastic matrix and tightly cohesively wound externally on the inner pipe (10) and the ring sleeve (18) of the joint element (12), which reinforcing jacket (14) is connected with the outer surface (34) of the ring sleeve (18) form-fittingly and/or materially joined,
• wherein the ring sleeve (18) exhibits a wave shape running in the axial direction,
• wherein the wave peaks of the wave shape are presented on the exposed outer surface of the transport pipe, and
• wherein sequential wave peaks (38) of the ring sleeve (18) exhibit a decreasing radial height going towards the free end of the ring sleeve (18).
