摘要： Transport pipe for high viscosity materials, in particular for concrete. The transport pipe includes an inner pipe (10) made of an abrasion-resistant plastic, at least one metallic joint element (12), as well as a reinforcing jacket (14) which envelops at least the internal pipe. In order to ensure a reliable and enduring joint between inner pipe and joint element, it is proposed in accordance with the invention, that the radially projecting collar of the joint element is defined by a ring-shaped end face (20) and by a thereto joined ring step (22) extending radially towards the inside of the pipe and recessed axially from the ring-shaped end face, and wherein the plastic material of the inner pipe (10) engages in the ring step (22) from the inside of the pipe.

摘要： A conveying pipe for transporting solids includes a pipe body and a pipe collar connected to at least one end of the pipe body. The pipe collar and the pipe end are coupled to each other by an interference fit at least in some sections in a coupling region in a longitudinal direction of the pipe body. In the coupling region, an anaerobically hardening adhesive is optionally arranged in craters or depressions. The conveying pipe is produced by roughening the pipe collar inner surface and/or the pipe end outer surface in a coupling region, cleaning the pipe collar inner surface and/or the pipe end outer surface, applying an anaerobic hardenable adhesive the pipe collar inner surface and/or the pipe end inner surface, and pressing the pipe collar onto the pipe end and/or pressing the pipe end into the pipe collar.
