Guide for the Electrofusion Jointing of Larger Diameter Polyethylene Pressure Pipes

Polyethylene piping systems are being increasingly accepted in larger diameters (above 315 mm) as a result of their proven performance advantages and the cost elective installation techniques which can be employed.

Electrofusion (EF) is an important and reliable jointing method for polyethylene pipes and a wide range of EF fittings approved to EN 12201-3/ EN 1555-3 are ordered in the market.

Usually EF training and certification is only applied to smaller dimensions, the common influencing factors for good installation practices and the preventive measures to avoid welding failures are often not understood.
