Pipe structure - whereas in butt fusion welding the pipes to be joined must have the same wall thickness, with electrofusion a difference in wall thickness can be accommodated. Electrofusion can also be used to join certain typesof multiple layer pipes, e.g. nylon lined polyethylene pipe for the conveyance of fuel.
Meaning of Electrofusion Electrofusion is a simple method of joining PE pipes in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. Prefabried fittings are used, incorporating an electricalPuhui Pipe manufacturer in China
MDPE electrofusion fittings are designed with built-in electric heating elements which are heated in order to weld pipe systems together. When the volPE100 ISO9001e is running through the fitting, the heater coils melt the inside of the fitting and the outside of the pipe wall, welding together the pipework and producing a very strong homogenous joint.
Electrofusion Installation Procedure Manual It is important to read and understand all instructions before attempting a fusion. Permanent field installations should be done only by operators who have been properly trained and certified as qualified. Should you have

Generally 1inch hdpe pipesing, HDPE pipe is butt fused by applying heat to prepared pipe ends and then pushing the pipe ends together with a pre-determined force to make a permanent butt fusion joint. It is a very simple process utilizing a properly sized butt fusion machine for the pipe size to be joined.

Electrofusion joint crush decohesion testing to ISO 13955 – plastics pipes and fittings – crushing decohesion test for polyethylene (PE) electrofusion asselies Shear and peel strength tests on geomerane HDPE liners to ASTM D6392 – determining the integrity of nonreinforced geomerane seams produced using thermo-fusion
The electrofusion process uses heat from electricity to melt the pipe and create an entirely homogenous joint that is stronger and more durable than the pipe itself. All electrofusion welding of PE pipes should be done by a trained operator, as there are important factors that may compromise the efficiency of the electrofusion process if performed incorrectly.
Before starting the welding procedure, it should be made sure that the pipe opening has a straight angle with respect to its own axis. If the angle is not straight, the pipe should be cut with guillotine (as seen in figure 12) to make it straight. . Figure 12
Electrofusion is a simple, cost-effective method for joining HDPE pipe. As an alternative to butt fusion, electrofusion is ideal for repairs and difficult connections of HDPE pipe. It has been successfully and cost effectively used for appliions such as pipe bursting, slip lining, dual containment, directional drilling, and manhole connections.
ELECTROFUSION SOCKET JOINTING 3. Mark the insertion depth on the pipe by holding the bagged fitting against the pipe. 5. Scrape one pipe end using a prescribed tool, for the length of the insertion depth plus 10-20mm. Ensure the whole surface area has 7.
