DWC
INTRODUCTION TO
system incorporates Integrated Coupling system with elastomeric seal ring for leak tight joining.
is a technically superior and cost effective solution for drainage and sewerage systems over conventional DI & RCC pipes with a steep reduction in installation time and equipment hiring cost. These pipes are available in sizes ranging from 100mm DN/ID to 1200mm DN/ID having ring stiffness ranging from SN2.5 to SN16. Inner layer can be in different colours, with the outer layer in black colour.
are manufactured as per following standards.
- IS 16098 Part II
- ISO-21138 Part III
- IS-14930
- BS EN 50086
FEATURES & ADVANTAGES
-
Longer Length
These pipes are available in 6m/12m length. Thus, the numbers of joints are less, resulting in faster installation.
-
Smooth Inner Surface
Offers least resistance to flow. Improves flow characteristics.
-
Lightweight
Easy to handle, transport and install. 70-90% weight reduction compared to DI/RCC pipe.
-
High Impact Strength
Does not dent/break during handling, transport and installation.
-
Long Service Life
Due to inherent advantages of no corrosion and shedding sudden overload by temporary deformation and recovery, these pipes have long service life,compared to conventional piping material.
-
Low Installation Cost
Installation cost is low on account of speedy jointing method, requiring no foreign material for jointing. Less trench width required, resulting in low civil work cost.
-
Deformation
Allows deformation and soil movement, which won’t damage structure under external load,unlike rigid pipes.
-
Chemically Inert
Does not corrode. Remains unaffected by gases/acid formed in sewers and chemicals present in sewage.
-
High Abrasion Resistance
Due to high abrasion resistance, wear and tear is low. Thus,last longer.
-
Ease in Jointing
Due to integrated coupling system with elastomeric sealing ring, the process of jointing is fast and joints are leak-proof.
-
Life Cycle Cost
Due to low product weight, low installation cost, least maintenance and longer life, life cycle cost is least.
-

JOINTING SYSTEM
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.
