Elbow 30° PE100 SDR11 PN16, d32-d315

  Datasheet (PDF) |   Product Range | Instructional Video

The Georg Fischer ELGEF Plus 30 degree electrofusion elbow is engineered for high-integrity directional changes in PE100 utility distribution networks carrying potable water or gas. Rated at 16 bar for water and 10 bar for gas across the SDR 11 range from d32 to d315 mm, this electrofusion fitting creates a fully end-load resistant, homogeneous joint without mechanical couplers or external thrust blocks, ensuring long-term operational reliability.

Technical specifications

The ELGEF Plus 30 degree elbow provides an optimal low-loss angular transition for pressurised water and fuel gas piping systems. Its integrated heating coils deliver controlled thermal energy directly to the fusion zone, establishing structural continuity between fitting and pipe.

• Material: Virgin PE100 resin approved by the PE100+ Association
• Pressure rating: 16 bar for water applications and 10 bar for combustible gas
• Dimensional standard: SDR 11 across metric diameters from d32 mm to d315 mm
• Wall thickness: Ranging from 3.0 mm at d32 up to 28.6 mm at d315
• Total fitting length: Ranging from 157 mm at d32 to 545 mm at d315
• Design service life: Estimated at 100 years under nominal operating parameters

Materials and standards

Manufactured from certified high-density polyethylene, the fitting conforms to European utility standards and retains exceptional mechanical durability under external ground stress. The virgin PE100 polymer ensures predictable long-term strength and resistance to slow crack growth across buried trench environments.

The material exhibits a tensile modulus of elasticity of 900 N/mm², a tensile yield stress of 25 N/mm², and a Charpy notched impact strength of 83 kJ/m² at 23 degrees Celsius. These physical properties safeguard the joint against cold-weather site impacts and structural soil settlement. The product complies with European standards EN 12201 for water supply systems and EN 1555 for combustible gas networks, supported by international quality certifications from DVGW, KIWA, ACS, and SVGW.

Installation and jointing

Jointing is performed through standard electrofusion control units, fusing the embedded wire coils into the pipe outer wall for an automated, leak-tight connection. The resulting homogeneous weld eliminates separate elastomeric gaskets and resists axial tension without requiring concrete anchor blocks.

A 30 degree deviation is ideal where utility trenches follow gentle surface contours or bypass buried infrastructure with minimal hydraulic head loss. For piping dimensions exceeding d315 mm, 30 degree deviations are accommodated by fabricated segmented HDPE elbows with long spigot ends, available in SDR 11 (PN 16) from 90 mm to 630 mm with a standard bending radius of approximately 1.5 times the external diameter.
