Abstract: A pipe connection in the form of a shrinkage connection formed from a connecting piece (1) having a surface structure (11), and a pipe (2) having an inner diameter which is smaller than the outer diameter of the connecting piece (1), wherein the surface structure (11) comprises a radially projecting flange (12) and at least one circumferential groove (13a, 13b, . . . ), the pipe (2) comprises a pipe end (21) which has been expanded in environmental temperature and connected to the connecting piece (1) by back-shrinkage. A sealing ring (3) is in the circumferential groove (13a, 13b, . . . ), which sealing ring (3) has an annular profile having an inner surface (31), being engageable with a connecting piece (1), and an outer surface (32), being engageable with the pipe (2), and the outer surface (32) comprises more than one annular ridge (33a, 33b, . . . ) adjacent to each other in axial direction.

Abstract: In a general aspect, a clamping ring for use on a pipe when making a pipe connection is configured such that when establishing the pipe connection an end of a pipe and the surrounding clamping ring are expanded simultaneously, wherein the clamping ring is made of a plastic material having memory properties such that after expanding, the clamping ring shrinks or contracts automatically, the clamping ring further comprising a chamfer on the inlet inner diameter edge of the clamping ring.

Abstract: For forming a clamping ring first the pipe is extruded. The extruded pipe is cut to form a pipe part. While extruding the pipe, its inner diameter is formed smaller than the outer diameter of a pipe onto which the clamping ring is positioned before making a pipe connection. The inner diameter of the pipe part is made larger by removing material from the inside of the pipe part but only over part of the length of the pipe part such that a stop edge is formed. The clamping ring is used on a pipe when making a pipe connection.
