Trelleborg designs and manufactures seals for clay pipes. We provide custom designed seals for the individual clay pipe producers pipes. Seals can be fitted either to either the pipe spigot end or integrated into the polypropylene fitting production as a captive gasket.
The joints are designed in cooperation with the pipe manufacturer to ensure the joint meets and exceeds the requirements of EN 295-1.
All joints accept angular deflection and shear load resistance without leakage, when tested under an internal or external pressure of 50kPa. Due to the excellent sealing function, Trelleborg’s clay pipe seal ranges offer improved performance against root intrusion allowing the pipes to be installed in both open trench and no-dig pipelines.
In addition, Trelleborg designs and manufactures specialist seals, which offer a leak free solution up to 4.5 bar internal and external water pressure.
