Abstract
Disclosed embodiments provide an electrofusion pipe coupler with mechanical support. The electrofusion pipe coupler comprises a coupler housing. A wire is configured and disposed within the housing. Electrodes are affixed to the coupler housing and in electrical contact with the wire. A threaded pattern is formed in an outer surface of the coupler housing. Gripping wedges are affixed to the coupler housing. Each gripping wedge extends from the coupler housing. A nut is attached to the coupler housing, engaging with the threaded pattern, and compressing the wedges against the connecting pipes. This serves to provide axial load transfer from the connecting pipes to the coupler housing via the wedges, thereby providing improved mechanical stability for such pipe assemblies.
