Abstract
A joint fitting for thermoplastic pipes. The fitting member has a receptor and an insert. The receptor fits snugly over the thermoplastic pipe, and the end of the pipe abuts against the fitting member. These respective contact surfaces are fused together by thermal welding, thus forming a socket seal and an abutting seal to strengthen the joint and to protect any glass fiber reinforcing layer of the pipe. One embodiment of the fitting also comprises a glass fiber reinforcing member that provides structural strength to the fitting member. In another embodiment, the fitting comprises an inner rim that fits inside the end of the thermoplastic pipe, thereby forming a double socket, abutted seal between the fitting and the pipe. Other embodiments comprise a valve for releasing gas and molten thermoplastic material during the thermal welding process.
