Abstract
A system and method for coupling pipes includes a first pipe having a tapered, spigot end; and a second pipe having a tapered, socket end adapted to internally receive the tapered, spigot end of the first pipe. The first pipe and the second pipe are made from a reinforced thermosetting resin (RTR) material. A thermal joining process is used to bond a thermoplastic material onto the RTR material of the first pipe, the second pipe, or both pipes. Upon application of thermal heating to the first and second pipes, the heat between the first pipe and the second pipe is sufficient to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe to the second pipe. A system and a method of coupling the first pipe and the second pipe may include the coupler made of RTR material.
