A method of fabricating a section of pipe fitting from a plurality of subsections and particularly a method of fabricating a non-linear plastic pipe fitting such as, for example, a tee fitting, wye fitting or the like is disclosed herein. The method includes forming predesigned complementary mitered edges in a plurality of plastic pipe subsections so that when the mitered edges engage one another in a complementary fashion, the subsections together take the shape of the desired fitting. The mitered edges are at least temporarily secured into engagement with one another by means of, for example, cement. Thereafter, a liquid mixture coating of elastomer resins such as polyurethane elastomer is applied, preferably by means of spray, to the external surfaces of the pipe subsections at the engaging mitered edges and allowed to set or cure to a tough but slightly resilient coating or band. In this manner, a more uniform coating or band can be readily applied to non-linear, irregular surfaces such as those defined by non-linear fittings. |
