Molded tapping member formed of a weldable plastics material

Abstract From the Canadian patent

A molded tapping member for connecting a branch line to a pipeline includes a U-shaped saddle piece with a shellshaped bight section and a pair of laterally spaced legs each extending outwardly from an opposite end of the bight section. The legs are formed of partial sections connected to one another by a film hinge. After positioning the tapping member on the pipeline by moving it radially toward the pipeline axis the, bight section and the legs are pressed around the pipeline. A heating wire mat is incorporated into the U-shaped saddle piece so that it fits closely around the pipeline for welding the tapping member to the pipeline. With the construction of this saddle piece a uniform …
