Abstract

A smart electrofusion fitting for connecting two pipe sections, the smart electrofusion fitting comprising an inner bush made of thermoplastic material and comprising one or more resistance wires, an outer bush and at least one sensor accommodated in the inner bush and/or the outer bush; wherein the inner bush and the outer bush comprise mechanical locking systems that mesh with each other in order to transmit axial and/or tangential forces, and wherein the resistance wires can be connected to an electric power source for melting a surface of the inner bush facing an external surface of each pipe section to create a welded joint.

Abstract

An electrofusion fitting for connecting to at least one pipe section fitted in an insertion end thereof, the fitting comprising an inner bush made of thermoplastic material and comprising one or more resistance wires, wherein the resistance wires can be connected to an electric power source for melting a surface of the inner bush facing an external surface of the at least one pipe section to create a welded joint; and an outer bush; wherein the inner bush and outer bush in axial dimension have mechanical locking parts with at least one gap between the inner bush and the outer bush, which mesh with each other to transmit axial and/or tangential forces.
