20090014121 | CHEMICAL FUSION OF NON-METALLIC PIPE JOINTS - The invention is a pipe joint that is particularly suitable for joining pipes composed of materials having a low surface energy and excellent resistance to solvents. The major components are an extrudable adhesive; a first pipe having a socket with an inside diameter, where said socket has a mouth, a self-centering bottom, and a substantially cylindrical wall with an inlet, an outlet, and an inner annular channel; a second pipe having an insertion section with an end and an outer annular channel, said second pipe having an outside diameter that is less than the inside diameter of the socket, where the difference in diameters defines a cap and where the outer annular channel lines up with the inner annular channel therein forming an interlocking keyway; and a flanged annular ring, where said annular ring has an inside diameter that enables it to be slid over the second pipe and a thickness that is comparable to the gap, and where the flange has a width that is sufficient to cap the mouth of the socket. When fully formed, the adhesive has changed to a solid material that substantially fills the gap and the interlocking keyway, and serves as a mechanical key in the interlocking keyway. The adhesive is preferably an alkyl borane adhesive | 01-15-2009 |
