ABSTRACT:
A pipe joint for fiber reinforced composite pipe has internal and external matching tapers with a low taper angle. A half round helical groove is formed in each of the internal and external tapers for receiving several turns of a ductile key. The pipe joint is usable on high strength lightweight fiber reinforced composite pipe having helically wound steel strips embedded in the fiber reinforced resin. The pipe joint on such pipe is on an enlarged portion of glass fiber reinforced composite built up on an end of the pipe. The steel strips are terminated at differing distances from the end of the pipe joint and the ends of all of the steel strips are completely embedded in the fiber reinforced resin.
