FAQ's

Q: What is Electrofusion?

A: Electrofusion is a welding process that involves joining HDPE (high-density polyethylene) pipes and electrofusion fittings by melting the material at their interface using electrical energy. This creates a strong, homogenous fusion joint, a bonding at the molecular level.

The completed fusion is stronger than the pipe itself. For more information, refer to PE100+ Association as a resource.

Q: How does the electrofusion process work?

A: Electrofusion involves the use of a specialized high-density polyethylene (HDPE) fitting with an embedded heating element. Before the fusion begins, the fitting is restrained to the outer wall of the polyethylene pipe.
The fusion process is controlled by a 24-digit barcode (the barcode is an international standard for electrofusion) found on the exterior of each fitting.

Our Strongbridge electrofusion processor will scan the barcode and perform the fusion process according to the parameters set forth by the barcode. The completed fusion will be stronger than the pipe itself. For more information, refer to Plastics Pipe Institute as a resource.

Q: What are the advantages of using electrofusion HDPE fittings?

A: Electrofusion HDPE fittings are engineered for extreme durability and offer several benefits, including your best choice for a leak-free system, chemical resistance, impact resistance at low temperatures, and resistance to corrosion and abrasion.

EF fittings are also lightweight and offer easy installation, they can be suitable for a variety of media, including water, liquids, gases, and slurries. Strongbridge offers the largest size and pressure-class range of electrofusion fittings available. As the originator of large-diameter electrofusion couplers and saddles, we’ll custom design and manufacture specific to your project needs.

Our electrofusion fittings are made with current PE100 resin in our ISO 9001 facility and meet international and domestic standards, including ASTM, AWWA, NSF, and FM Approvals.

Q: What resin are your electrofusion fittings and molded fittings manufactured with?

A: Our Strongbridge HDPE electrofusion fittings and molded fittings are manufactured using high-density polyethylene (HDPE) 4710 / PE100 virgin resin.
