DWC Pipes

Double Wall Corrugated ( DWC ) HDPE pipes. Double Wall Corrugated ( DWC ) HDPE pipes are similar to normal HDPE pipes except that they have different external & internal surfaces which gives them additional strength and stiffness.
DWC Pipes are manufactured using HDPE polymer. These pipes are resistant to various types of gases & chemicals which are generated due to putrification of various ingredients flowing in the system. IS 16098
TeleRex Pipes are specially designed for underground cable ducting. Made from HDPE, TeleRex caters to the Power, Signal, Telecom Cable and Optical Fibre Cable Ducting requirements in India. It is a widely utilized product by many sectors such as Indian Railways, Airport Authorities, State Electricity Boards, Power Distribution Companies, Public Works Departments, Telecom Companies and so on.

DWC ( Double Wall Corrugated ) Pipes are manufactured using HDPE polymer. These pipes are resistant to various types of gases & chemicals which are generated due to putrification of various ingredients flowing in the system. 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. 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.

Pipe material propertyFlexible pipeRigid pipe
Pipe design (structural
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 environmentDue 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 jointingSocket & Spigot joint with elastomeric sealing ring1. Coller joint with help of cement morter
2. Socket & Spigot joint with rubber ring and cement morter
Pipe weightVery lightHeavy (19-20 times heavy than DWC* pipes
Pipe roughness coefficient0.009 Much higher flow rate due to less roughness coefficient and hence during design, pipe diameter requirement is less as compared to concrete & DI pipes0.014 Lesser flow rate due to more roughness coefficient and hence during designing, pipe diameter requirement will be higher than DWC* pipe
Handling of pipeEasy due to its light weightDifficult due to its heavy weight
Corrosion resistanceHighly corrosion resistanceNot resistant to Hydrogen Sulfide gas which is present in all sewer pipes, hence Sulphate resistant cement is used during manufacture
InstallationGood flexibility, low requirements for foundation base for laying, good bendingHigh rigidity, high requirement for foundation base for laying, not easy to handle & bend, difficult to connect with other pipe
Pipe classStiffness class SN 4, SN 8 (Non-Internal Pressure Applications)NP 1, NP 2, NP 3, NP 4 (Non-Internal Pressure Applications)
Pipe stacking on siteStacked on plain ground. Smaller diameter pipes can be nested in bigger diameter pipesStacked on plain ground seperately. Can not be nested due to its heavy weight
Pipe handling on fieldLight weight hence safe in manual handling, has high impact resistance and is non-breakable due to miss handlingHeavy weight hence poor safety during handling, may lead to damage due to mishandling
Working featuresHigh safety under buried installationLow safety under burried installation
Life timeMore than 50 yearsAround 15-20 years
