A pipe has an innermost layer, outside of which there is an inner electrode layer, outside of which there is an insulating layer, outside of which there is an outer electrode layer. The innermost layer is made of plastic by continuous extrusion and the insulating layer is made of foamed plastic.

Pipe

A method for the manufacture of a heat fusion fitting, which comprises i) forming a body () comprising at least a first layer of a first cross-linked polymeric material, ii) embedding or partly embedding a ferromagnetic heating element () in a second polymeric material () to form an insert (), the ferromagnetic heating element () having a Curie temperature equal to or greater than the crystalline melting point or softening point of the second polymeric material (), and iii) assembling the body and the insert () to form the fitting.

Heat fusion fitting

A method for the manufacture of a heat fusion fitting, which comprises i) forming a body ( ) comprising at least a first layer of a first cross-linked polymeric material, ii) embedding or partly embedding a ferromagnetic heating element ( ) in a second polymeric material ( ) to form an insert ( ), the ferromagnetic heating element ( ) having a Curie temperature equal to or greater than the crystalline melting point or softening point of the second polymeric material ( ), and iii) assembling the body and the insert ( ) to form the fitting.

A pipe connector ( ) for a multi-layer composite pipe, the pipe comprising at least one reinforcing layer ( ), or layer of high axial strength, at least one inner thermoplastic layer ( ) and at least one outer protective layer ( ), the connector comprising: (i) a hollow, tubular enclosure ( ) adapted to receive the pipe; (ii) fusion means adapted to make a fusion connection with the inner thermoplastic layer of the pipe; (iii) mechanical gripping means ( ) adapted to grip the reinforcing layer, or layer of high axial strength of the pipe; and (iv) optionally sealing means ( ) adapted to form an environmental seal with the outer protective layer of the pipe, the electrofusion means ( ), mechanical gripping means and optional sealing means being disposed within the enclosure and the enclosure being adapted, in use, to apply a constraining force to the mechanical gripping means and the sealing means.

A method for renovation of pipelines, comprising introduction of lining layers into the existing pipeline, the lining layers corresponding in length to the length of the pipeline to be renovated. The lining layers consist of fusible polymers and are presurized and fused together by the introduction of a heat source into the inside of the innermost lining layer.

The present invention relates to a branch pipe connection for connecting a branch pipe to a lightly constructed underground sewage and drainage pipe. The connection includes a locking ring and a sleeve that are arranged against one another and can be tightened in their axial direction. The connection further includes a support flange. The locking ring has a slit by means of which the locking ring can be placed inside the underground sewage and drainage pipe through a hole made for the branch pipe from outside the underground sewage and drainage pipe. The pipe connection also comprises a sealing that is arranged to extend from the inner surface of the underground sewage and drainage pipe as far as the sleeve. A compact, dismountable connection for improving the ring stiffness of the underground sewage and drainage pipe is produced in this way.
