Electrofusion is a fast, effective, and extremely durable way to connect plastic pipe using fittings with specialized types of materials. These specialized materials in the fitting are actually electric heating elements that, when connected to an electrofusion machine, heat up to melt the HDPE (high density polyethylene) or MDPE (medium density polyethylene) pipe and fitting. At the same time, they do not heat up other areas of the pipe or fitting, creating an effective seal that is actually as strong as the surrounding plastic.
The electrofusion machine is the power source that provides the energy to heat up the elements in the fitting and create the weld. The benefit of this type of system is that the construction of the pipeline can be done anywhere, and there is no need to have power or even a generator at the site. Instead, the small, compact machine that is highly portable is simple to use and provides the energy to create the weld.
Factors to Consider
For use in the field, the electrofusion machine needs to be designed to be lightweight, effective, and a “smart” system. The new technology in these machines can actually read the codes on the pipe and apply the required settings to generate the power required for the electrofusion process of the detected materials.
With these smart devices, be sure there are additional options for manual seeing and for barcode input. This is particularly important with older HDPE and MDPE pipe, that may not be readable. In addition, look for systems that have a wide range of setting options, error message readouts, and the ability to use a wide range of different data sources.
With any electrical equipment, be sure the system offers a full range of safety features for the operator. This includes both visual and audible confirmation of the electrofusion success or failure, as well as emergency stop capability and simple, user-friendly controls and setup.
