摘要： The present invention relates to a pipe coupling for connection to a pipe end of a pipe made of polymer material and intended preferably for tap water or heating installations. The pipe coupling includes an inner sleeve intended for insertion into the pipe end and for abutment with the inner surface of said pipe end. The coupling further includes an outer sleeve intended for abutment with the outer surface of said pipe end. The outer sleeve is provided with a slot-like opening and means for adjusting the width of said opening. When the outer sleeve is in a tightened, adjusted state, the sleeve will be internally and externally cylindrical. A center axis through the outer cylindrical surface of the outer sleeve is spaced at a distance from a center axis through the inner cylindrical surface of the outer sleeve. In the tightened, adjusted state of the outer sleeve, the internal radius of said sleeve is smaller than the external radius of said pipe end.

摘要： The invention relates to a multilayer plastic pipe (1), preferably for use in heating systems. The multilayer pipe comprises an inner core (2) and a barrier layer (6) surrounding the core and preventing oxygen diffusion through the multilayered pipe. The core (2) is made of a material having viscoelastic properties, preferably cross-linked polyethylene, and the barrier layer (6) is surrounded by an outer layer (8) of a material having adhesive properties. The invention also relates to the use of a multilayer pipe for providing pipe couplings.

摘要： A pipe connection comprises a connecting piece, a pipe and a clamping ring. The pipe and the clamping ring are made of a material having memory properties. An end of the pipe and the clamping ring have been reversibly expanded co-jointly and firmly and sealingly shrunk to the connecting piece by back shrinkage. Preferably the clamping ring is made from a cross-linked polyolefin by injection molding.

摘要： A pipe end is expanded by an expander tool (1) comprising a plurality of jaws (10), which are radially movable in relation to a center axis between a retracted position and expanded position. The jaws (10) when retracted are intended to be inserted into the pipe end. The jaws (10) have outer jaw surfaces which are intended for engagement with the inner surface of the pipe end and which lie adjacent to one another in the retracted position of the jaws (10). The tool (1) further comprises a piston (2) or a cone with a tapered end for moving the jaws (10) between said positions and means moving the piston (2) or the cone in a reciprocating manner in the axial direction for expanding the pipe end. The tool (1) further comprises support structures whereby the jaws (10) are supported in a circumferential direction in the expanded position. A method for expanding a pipe using such a tool is also disclosed.
