ABSTRACT:
A pipe welding connector for joining pipe sections that have been internally coated with a heat sensitive coating material. The connector is arranged so that during the welding process, the coating remains below its degradation temperature. The connector has a first fixture at the end of one pipe section and a second fixture at the end of another pipe section. The first and second fixtures, when brought into abutting relationship, can be butt welded together to form the pipe welding connector. The second fixture is a cylinder that outwardly diverges into a bell and the opposed marginal end is of constant inside diameter and is attached about the exterior of a pipe section. Part of the pipe section extends from the belled marginal end and forms a stinger. The first fixture has an enlarged interior that telescopingly receives the stinger therein and further includes a belled marginal terminal end of a diameter equal to the diameter of the belled marginal end of the second fixture. This unique structure allows a first fixture to be formed on one end of a pipe section and the second fixture to be formed on the other end of the same pipe section so that series connected pipe sections can be welded together to form a pipe line without destroying the internal coating.
