DN600-1400 Glassfiber Reinforced Plastic (GRP) Pipes

The broader SUBOR GRP pipe product family covers nominal diameters from DN200 to DN4000 and pressure ratings from PN1 to PN40 bar. Standard stiffness classes are SN2500, SN5000 and SN10000 N/m², while higher project-specific stiffness classes may be designed for special applications such as jacking pipes. These values describe the overall SUBOR GRP pipe product portfolio and shall not be interpreted as a DN-by-DN pressure or stiffness matrix for each EPD diameter category. The actual DN, PN and SN combinations are project/orderspecific and are reflected in the annual production data used for the weighted-average calculation. Higher project-specific stiffness classes may be designed where required, particularly for special applications such as jacking pipes. Standard pipe lengths are 6 m and 12 m, while special lengths up to 15 m may be manufactured upon request. The pipes are typically connected by coupling systems with elastomeric gaskets; the final joint type depends on the pressure class, installation method and project requirements.
