What is electrofusion piping?

Electrofusion is widely used in the installation of polyethylene (PE) piping for gas pressure applications. Electrofusion fitting designs vary between manufacturers and historically each manufacturer had developed and qualified its own installation procedure.

How does electrofusion work?

The electrofusion process works by introducing a controlled electrical voltage to the heating coil, which in turn generates heat to melt the fitting and pipe surfaces. As the polyethylene surfaces melt they also expand in volume to close any gaps between the pipe and fitting.

Why is electrofusion important?

With electrofusion, end-users can overcome difficult on-site conditions, such as space limitations, resulting in better system performance (e.g., no leakage). AGRU has developed robust electrofusion technologies to streamline and support the installation of large-diameter solid-walled HDPE pressure pipes.

What are Electrofusion Fittings used for?

Electrofusion fittings are qualified for various uses including regulated natural gas distribution, potable water, fire suppression systems, chemical pipe and waste, and industrial piping. Specification for Electrofusion Type Polyethylene Fittings for Outside Diameter Controlled Polyethylene and Cross linked Polyethylene (PEX) Pipe and Tubing.

How reliable are AGRU electrofusion fittings?

AGRU’s electrofusion couplers demonstrated superior performance in an accelerated FNCT test, outperforming other suppliers by a factor of five. Electrofusion fittings are FM-approved for firefighting systems, withstanding pressure surges up to 25 bar, proving their reliability in critical applications.

How are electrofusion fittings packaged?

Electrofusion fittings are packaged in sealed plastic bags as protection against accumulation of dust, dirt, and contamination. The bag should remain in place during normal handling and should only be removed immediately prior to installation.
