Electrofusion (EF) jointing is used to join polyethylene (PE) water main pipe sections and fittings where butt fusion welding is not appropriate — typically for couplers, elbows, tees, reducers, and saddle tapping assemblies. All EF jointing is carried out in accordance with WIS 4-32-08 (Specification for the Fusion Jointing of Polyethylene Pressure Pipeline Systems Using PE80 and PE100 Materials), as required under IW-CDS-5020-03 Section 4.10.3.3. Our EUSR certified welders maintain full fusion traceability records per joint, and GPS co-ordinates are recorded at each joint location for submission as part of the Final Documents required for Conformance Certificate application by Irish Water.
What We Carry Out
- EF coupler jointing for PE80 and PE100 HDPE pipe, all diameters
- EF fittings — elbows, tees, reducers, end caps
- Electrofusion saddle tapping assemblies — 2-minute hydraulic test at 18 Bar applied to each fused saddle fitting prior to tapping, per WIS 4-32-08
- EUSR certified welders — current logbook holders
- Full fusion traceability records per joint: pipe batch, fitting batch, welder ID, machine serial, fusion parameters, date and time
- GPS joint location records submitted as part of Final Documents
- Works carried out in accordance with WIS 4-32-08 and IW-CDS-5020-03
