The ELGEF Plus 90 degrees elbow is an engineered PE100 spigot fitting manufactured by Georg Fischer (GF Piping Systems) for reliable directional changes in pressurized polyethylene piping networks. Designed for buried utility infrastructure and industrial installations, this fitting features long spigot ends suited for electrofusion couplers and butt fusion welding. It delivers exceptional chemical resistance, full flow characteristics, and dependable pressure containment across drinking water, gas, and industrial fluid applications.

Technical specifications

The fitting is produced from virgin PE100 high-density polyethylene to guarantee structural integrity and long-term hydrostatic strength under operational pressure. It complies with rigorous international manufacturing benchmarks, including FM 1613 certification for fire protection mains.

• Material: PE100 high-density polyethylene with superior resistance to stress cracking.
• Pressure rating: PN16 bar for water and PN10 bar for gaseous distribution media in SDR11.
• Alternative series: SDR17 execution rated at PN10 bar water and PN5 bar gas for lighter networks.
• Approval: FM 1613 certification at 15 bar for certified fire protection diameters.
• Connection geometry: Extended spigot ends engineered for electrofusion and butt fusion.

The smooth internal bore geometry prevents sediment buildup and minimizes localized head loss throughout the piping system. Because the fitting is manufactured to exact dimensional tolerances, the SDR rating of the elbow corresponds directly with the SDR of the connected pipe to maintain consistent wall thickness and full structural continuity under continuous hydraulic load.

Installation and jointing

Extended spigot legs provide ample clamping length for electrofusion couplers and direct alignment in butt fusion welding machines. This versatile dual-jointing design permits rapid assembly in confined trenches using electrofusion or economical shop prefabrication via butt fusion.

When carrying out butt fusion or electrofusion procedures, pipe ends and spigot zones must be properly scraped to remove oxidized surface layers, cleaned with dedicated wipes, and aligned without mechanical stress. As an authorised Georg Fischer distributor, BigWeld supplies the complete ELGEF Plus system along with the necessary electrofusion control units and butt fusion tooling to ensure dependable joint integrity on site.

Applications

This 90-degree PE100 spigot elbow is engineered for pressurized municipal water supply, natural gas mains, fire protection rings, and demanding industrial fluid conveyance. The monolithic nature of the fused joints eliminates leak paths, providing outstanding reliability in underground municipal networks, agricultural irrigation systems, and industrial treatment facilities where corrosion resistance is essential.
