Jointing Systems

Drainage Pipe system incorporates Integrated Coupling system with elastomeric seal ring for leak tight joining.

Sealing ring plays a vital role in making joints leak-proof. Elastomeric Sealing Rubber Ring

  • Elastomeric sealing ring made of EPDM with resistance to UV exposure, ozone, ageing, weathering, and many chemicals - great for outdoor application.
  • Low electrical conductivity
  • Resistance to steam and water
  • Surface of the ring is smooth, free from pitting cracks, blisters, air marks, and any other imperfection that may affect its behavior in service
  • Elastomeric sealing rings are made in accordance with one of the type (Type 1 to Type 6) of IS 5382 standard.

The jointing procedure of DWC pipes is easy and simple to adopt and is illustrated below.
