Abstract: The tube conduit connection contains a tube conduit connector (1) including at least one connecting member (2,2',2") and a tube end (6) which is made of a thermoelastic cross-linked polyolefin and which is firmly and gas-tightly applied to the connecting member by expansion and self-reconversion of the tube end. The connecting member (2,2',2") contains a surface structure (3,3',3") which is outwardly followed by an elongation (4,4',4") having a chamfered end (5,5',5").

Abstract: The cross-linked plastic material is shaped in the softened state, for example, by blow-molding, deep-drawing, pressing, rolling, calendering or stretching and cooled below the softening range while retaining the thus formed shape.

Abstract: Shaped articles, particularly tubular shaped articles, are formed by a process comprising molding a crosslinkable synthetic plastic material into a first molded shape, crosslinking the plastic material at a temperature in excess of the crystalline melting point of the material, subjecting the crosslinked first shape to a working operation to form a second configuration shape and subjecting specific areas of the second shape to a heat treatment thereby forming a deformation in the specific area. Extruded tubular materials subjected to a stretching operation tend to seek their original shape upon heat treatment thereby making the degree of deformation possible nearly equal to the degree of stretching.
