The EF Stub End is the critical transition piece enabling a safe and detachable flange connection between a Polyethylene pipeline and dissimilar materials like valves, pumps, or steel pipes. One end of the fitting is designed for a permanent electrofusion connection to the PE pipe, while the opposite end forms a flat face and neck. This face, when used with a metal backing ring, allows for a bolted, mechanical connection. This design ensures that the fluid media only contacts the corrosion-resistant PE material, effectively preventing chemical corrosion or fluid contamination originating from metallic components. Simultaneously, the flange connection provides a mechanical seal capable of withstanding high operating pressures, and it allows for equipment maintenance or replacement without damaging the pipeline system. The EF Stub End is widely applied in water treatment plants, pumping stations, and all interfaces where PE pipelines need to reliably connect to existing metal networks or components requiring periodic servicing.
