Description
Ring Stiffness Options
SGK pipes are available in a range of structural stiffness classes to suit varying installation conditions and loading requirements.
| EN 13476 Classification | DIN 16961 Classification |
| SN2 (2 kN/m²) | Class 3 (SR24 – 8 kN/m²) |
| SN4 (4 kN/m²) | Class 4 (SR24 – 16 kN/m²) |
| SN8 (8 kN/m²) | Class 5 (SR24 – 31.5 kN/m²) |
| SN16 (16 kN/m²) | Class 7 (SR24 – 125 kN/m²) |
Please note that the EN 13476 and DIN 16961 stiffness classifications are based on different test methods and should not be considered directly equivalent.
Features & Benefits
- Extensive Diameter Range
Available in sizes from 800 mm to 2500 mm, making the system suitable for major drainage and infrastructure projects. - Optimised Structural Design
Offered with smooth or profiled external walls, with a choice of structured wall profiles to achieve the required moment of inertia and ring stiffness. - Excellent Hydraulic Performance
The smooth internal bore promotes efficient water flow while minimising friction and sediment build-up. - Reliable Electrofusion Jointing
Integrated socket and spigot connections support electrofusion welding, providing robust, permanent and watertight joints. - Alternative Gasketed Joint System
A socket-and-seal connection option is also available where gasketed jointing is preferred. - Secure Leak-Tight Connections
High-integrity jointing systems ensure reliable long-term sealing performance throughout the network. - Lightweight Construction
Considerably lighter than traditional concrete alternatives, simplifying transportation, handling and installation while reducing construction costs. - Outstanding Chemical and Abrasion Resistance
Manufactured from HDPE, providing exceptional resistance to aggressive chemicals, corrosion and abrasive media. - Electrically Non-Conductive
Inert to stray electrical currents, eliminating corrosion risks associated with metallic materials. - Colour Options
Available in all black or with a blue internal wall and black external wall for application-specific identification. - Versatile Infrastructure Solution
Suitable for gravity sewerage, drainage, culverts, inspection chambers, storage tanks, siphons and a wide variety of underground civil engineering applications.
