Couplings for Reinforced Thermoplastic Pipe (RTP)
In 2000, Shand UK started a programme of work to develop a swaged coupling for attaching to reinforced thermoplastic pipe (RTP). The potential burst pressure, coupled with the projected 25 year service life of RTP meant that a traditional internal or external swaged coupling used for reinforced rubber hose was unlikely to be consistently successful. As a result of this potential problem, Shand UK developed the concept of Dual Swaging which as its name suggests is the combined action of both internal and external swaging. When either internal or external swaging are undertaken on their own, the swaging process in gripping down on the pipe, naturally distorts the axial line of the reinforcement layers and can ultimately weaken them which can result in a pipe failure at lower than expected operating pressure.
RTP pipe comprises three layers; a PE liner, a mid reinforcement layer and a PE outer cover.
