The two common methods of welding PE pipe are butt fusion and electrofusion (EF). Butt welding has been used successfully in Australia since the 1960’s and EF since the early 1980’s. These methods are used widely around the world with something in
3.2.2 Procedure 2, Butt Fusion—The butt-fusion procedure in its simplest form consists of heating the squared ends of two pipes, a pipe and a fitting, or two fittings, by holding them against a heated plate, removing the heater plate when the proper melt is

procedures from multiple pipe producers and they are conservative given the expectation that the fusion operator must perform the fusion process consistently across a wide range of possible job site conditions. This paper explores the feasibility of accounting for
Pipefusion Engineering for polyethylene butt fusion welding to ISO 21307. 450 Polyethylene Pipeline Polyethylene pipe welding; Butt welding involves the heating of two pipe ends to fusion temperature 200 to 240 degrees Celsius and then subsequently joining the two ends by applying force using a hydraulic carriage.

pipe, the crystalline portion of the HDPE chains ‘un- fold’, and the melt increases in volume by 28%. This explains the reason that a circular melt-bead forms around the perimeter of the pipe end on the flat heater plate, even though the fusion machine pipe
ISO 21307 specifies three proven butt fusion jointing procedures for pipes and fittings with a wall thickness up to and including 70 mm, taking into consideration the materials and components used, the fusion jointing procedure and equipment and the quality assessment of the completed joint.
Butt-Fusion (BF) and Electro-Fusion (EF) welding processes are the most common joining processes for HDPE pipelines. Defects for BF welds include planar flaws due to poor welding processes, cold fusion welds caused by incorrect welding procedures, inclusion of particulates and weld mismatch.
Butt fusion involves the simultaneous heating of the ends of two pipe/fitting components which are to be joined, until a molten state is attained on each contact surface. The two surfaces are then brought together under controlled pressure for a specific cooling time and a homogeneous fusion joint is formed.
Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself. The principle of
