The Georg Fischer ELGEF Plus 90-degree injection-moulded bend in PE100 SDR11 provides direction changes for high-integrity polyethylene piping systems. Engineered for utility and industrial networks, this fitting covers dimensions from d32 to d500 mm with an operating rating of 16 bar for water and 10 bar for gas distribution. Its compact 1xd bending radius minimises installation footprints while maintaining continuous pipeline pressure ratings.

Technical specifications

This SDR11 injection-moulded bend is dimensionally matched to standard polyethylene piping across the entire diameter span from d32 up to d500 mm. The tight 1xd radius ensures reliable hydraulic routing in constrained trenches, chambers, and manifold assemblies where sweeping pipe bends cannot fit.

• Nominal diameters: d32 to d500 mm (DN25 to DN500)
• Pressure rating: 16 bar for water distribution, 10 bar for gas service
• Dimension ratio: SDR11 with wall thicknesses ranging from 2.9 mm to 45.5 mm
• Geometry: Compact 1xd bending radius (R=32 mm to R=500 mm)
• Spigot dimensions: Spigot length L from 46 mm to 212 mm, total z-dimension from 78 mm to 710 mm

The integrated long spigot ends provide sufficient clamp and fusion zone clearance, avoiding the flow restrictions and pressure de-rating associated with fabricated segmented fittings.

Materials and standards

Manufactured from virgin PE100 resin approved by the PE100+ Association, this fitting delivers a certified 100-year design life under nominal operating conditions. The formulation offers high resistance to slow crack growth, external point loading, and chemical degradation across aggressive utility environments.

The ELGEF Plus fitting conforms to EN 12201 for pressurized water supply and EN 1555 for combustible gas conveyance. International quality certifications include DVGW, KIWA, and FM 1613 approvals (15 bar on selected sizes), alongside comprehensive marine classifications from DNV-GL, Bureau Veritas, and Lloyd's Register for offshore installations and marine construction.

Installation and jointing

The fitting features extended spigots engineered for dual compatibility with electrofusion couplers and conventional butt-welding machinery. This jointing flexibility accommodates prefabrication in clean workshop environments as well as rapid installation or trench tie-ins on active job sites.

For electrofusion, the fitting pairs with ELGEF Plus couplers, while standard heating-element butt welding proceeds according to DVS 2207 welding parameters. BigWeld supplies the complete ELGEF Plus product range across Europe as an authorised Georg Fischer distributor, providing technical support for utility mains, industrial processes, agricultural irrigation headers, and fire protection systems.
