    摘要： The fixed joint of the swing diffuser assembly includes a tee connected to the gas supply line. The swing joint includes a second tee. The upper leg of the swing diffuser comprises dual parallel pipes having elbows turnable in the ends of the tees. The dual pipes together comprise the upper leg and with the two joints provide the structural rigidity which particularly allows the joints to be constructed of molded plastic and the pipe of reinforced resin.

    摘要： 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.

    摘要： Pipe connection for joining two pipes having two concentric pairs of half shells around the joint ends of the two pipes to be connected, the inner pair being larger in diameter than the pipes and the outer pair being larger than the inner pair, with largearea bonding interstices therebetween. The gaps between half shells are angularly staggered between the inner and outer pairs. Preferably the gaps are filled up with the same bonding agent used to interconnect the pipes with the pairs of half shells.
