Corfit DWC Pipes are manufactured as per IS 16098 (Part-2), have a smooth internal surface and corrugated external surface. The corrugated external surface provides greater stiffness, withstands soil movement & takes higher loads (static & dynamic), whereas the internal surface helps in smooth flow of sewerage.
Corfit DWC Pipes are available in SN 4 and SN 8 stiffness classes with sizes from 100 mm to 1,000 mm ID. These pipes have a standard length of 6 metre and are available with rubber ring jointings.
Color Available: Orange
Specifications
| Parameters | DWC (HDPE Double-wall Corrugated) Pipes | RCC Pipes |
|---|---|---|
| Length of Pipe Available | 6.0 m | 2.0 - 2.5 m |
| Size/ Diameter Available | 100 - 1000 mm | 150 - 600 mm |
| Pipe Material Property | Flexible pipe | Rigid pipe |
| Pipe design (structural property) |
Due to its flexibility it allows deformation in diameter as well as in joints under external load and soil natural movement and hence operates years after years without affecting the environment | Due to its rigid nature it could not deform and hence gets damaged under external load or leaks due to natural soil movement at joint. Sewer water could also leach in ground water harming the environment |
| Pipe jointing | Socket & Spigot joint with elastomeric sealing ring | 1. Coller joint with help of cement morter 2. Socket & Spigot joint with rubber ring and cement morter |
| Pipe weight | Very light | Heavy (19-20 times heavy than DWC* pipes |
| Pipe roughness coefficient | 0.009 Much higher flow rate due to less roughness coefficient and hence during design, pipe diameter requirement is less as compared to concrete & DI pipes | 0.014 Lesser flow rate due to more roughness coefficient and hence during designing, pipe diameter requirement will be higher than DWC* pipe |
| Handling of pipe | Easy due to its light weight | Difficult due to its heavy weight |
| Corrosion resistance | Highly corrosion resistance | Not resistant to Hydrogen Sulfide gas which is present in all sewer pipes, hence Sulphate resistant cement is used during manufacture |
| Installation | Good flexibility, low requirements for foundation base for laying, good bending | High rigidity, high requirement for foundation base for laying, not easy to handle & bend, difficult to connect with other pipe |
| Pipe class | Stiffness class SN 4, SN 8 (Non-Internal Pressure Applications) | NP 1, NP 2, NP 3, NP 4 (Non-Internal Pressure Applications) |
| Pipe stacking on site | Stacked on plain ground. Smaller diameter pipes can be nested in bigger diameter pipes | Stacked on plain ground seperately. Can not be nested due to its heavy weight |
| Pipe handling on field | Light weight hence safe in manual handling, has high impact resistance and is non-breakable due to miss handling | Heavy weight hence poor safety during handling, may lead to damage due to mishandling |
| Working features | High safety under buried installation | Low safety under burried installation |
| Life time | More than 50 years | Around 15-20 years |
