Two Part Double Walled Fitting for Plastic Pipe

A method has been proposed to use pre-fabricated fittings for outer pipe of double wall piping systems. The fittings are matching halves which may be snapped together around carrier pipe fittings and cemented.

With double wall piping systems it is difficult to provide fittings for the outer pipe. Previous approaches have involved cutting an existing fitting, placing it about the inner pipe fitting and then cementing in place. This is neither effective nor absolutely leakproof. Other methods such as containment piping are too bulky.

The new fittings would be molded as two-part snap together items from an appropriate plastic. They would include elbows, bushings and tees such as the one illustrated in Fig. 1. Each fitting would include a snap-in half equipped with a ridge Fig. 2-1 and a locking half equipped with a groove Fig. 3-2 into which the ridge will snap to provide the assembled fitting Fig. 4. In assemblying the fitting cement would be applied to the edges and the two halves snapped into place around the carrier pipe.
