Abstract
A pipe joint for joining pipes composed of materials that are difficult to adhere. The major elements are an extrudable adhesive; a first pipe having a socket with an inside diameter, where the socket has a mouth, a self-centering bottom with a gasket, a cylindrical wall with a plurality of ports, and an inner annular channel. A second pipe has an insertion section with a squared-off end and a rolled groove. The second pipe having an outside diameter that is less than the inside diameter of the socket, where the difference defines a coaxial cavity with a width. The rolled groove serves as a distribution channel while the adhesive is a liquid, and upon curing the solid adhesive functions as a retaining ring. A flanged annular ring, potentially aided by a compression apparatus, caps the cavity, centers the insertion section, and maintains compression. The adhesive includes alkyl-borane-adhesives.
