“…In tight-fit joints, the melt has nowhere to go, so the pressure rises, resulting in compressive stresses after solidifying, according to the author. 18 Riahi et al 25 attempted to investigate the effect of clearance size and analysed gaps in the range of 0.4-1.5 mm. However, they did not test actual couplers and pipes, but instead used simplistic samples made from two flat PE plates with heating wire attached to one; the plates were spaced away from each other with thin plates of aluminium; such setups were then placed in a fixture with adjustable clamping pressure and connected to an EF control unit.…”

Oil and gas operators have been looking for a more reliable and cost-effective material for their pipelines to substitute steel in pipes and connectors. Reinforced thermoplastic pipes are a popular choice for this purpose, but they are still mainly using steel connectors, which have limited lifetimes due to corrosion. For this reason, efforts are being made to design a non-metallic electrofusion coupler to connect these. This article looks at the current state of the art in electrofusion welding of standard polyethylene pipes and aims to find possibilities of applying this technology to reinforced thermoplastic pipes.
