Connex Pipe System

The alternative in the sewage sector

The CONNEX Sewer Pipe System DN/OD 315 – 800 (SDR 34, SN 8) comes with a complete range of fittings offering utility companies, developers and contractors a real alternative to traditional materials in the sewage sector. With installation depths of 0.8 to 6.0 m and the installation pursuant to EN 1610, traffic loads of up to SLW 60 (HA20) are possible.

The Connex Sewer Pipes are equipped with the permanently integrated two component CI® seal system. The CI® seal is firmly integrated into the pipe socket; it cannot be dislodged and therefore it cannot be forgotten or pressed out when joining pipes together. Even with an angled connection of up to 3° the push fit connection is permanently tight.

The advantages in practice:

  • Ring stiffness minimum 8 kN/m² (SN 8)
  • Root-proof pipe connection
