UV Stabilized PPR-C Top layer:
- UV Stabilizers contains various chemical properties, which gives the protection against UV light by various chemical mechanisms.
- Colors like Black, Green already have good resistance to UV rays, but addition of UV stabilizers further enhance the light and thermal stability of product.
- UV stabilizers impart long term durability and enhance life of the product.
Anti-microbial PPR-C Inner Layer
Anti-Microbial Layer Prevents the growth of Bacteria/Algae/Microbes etc inside the pipe which makes suitable for the Usage of any Clean Water or Liquid Food Supply Application.

TECHNICAL & COMMERCIAL COMPARISON
| Properties | MS Pipes | CPVC Pipes | PPR Pipes |
|---|---|---|---|
| Service Life | 3–5 years | 15–20 years | 50 years |
| Food Grade | Poor due to corrosion issues | The solution used for jointing the pipes might contaminate the water. Non-hygienic in nature. | Hygienic, CFTRI approved – can supply clean water and liquid food. |
| Leakage | High chance | High chance due to solution-based jointing | Negligible chance due to socket fusion jointing |
| Heat Loss | High | Negligible | Negligible |
| Thermal Conductivity | Very High (45 W/mK) | Low (0.3 W/mK) | Low (0.23 W/mK) |
| Insulation Requirement in Chilled Water Supply | More insulation thickness required due to high thermal conductivity | Pipes not recommended for chilled water supply | Lower insulation thickness than MS as thermal conductivity is quite low |
| Maintenance Cost | High after 3–4 years | High after 5–6 years | Negligible up to 15–20 years |
| Corrosion Resistance | Nil | Excellent | Excellent |
| Friction | Very High | Low, approx. 4 ft/100 ft | Negligible due to smooth layer, approx. 1.5 ft/100 ft |
| Weight | Very heavy | Very light due to which transportation cost decreases by 3 times | Very light due to which transportation cost decreases by 3 times |
| Painting Cost | Additionally high for painting the pipes according to standards | None | None |
| Young’s Modulus | NA | Approx. 3275 MPa, making the pipe rigid and brittle | Approx. 850 MPa, making the pipes tough and ductile |
| Temperature Resistance | Applicable for higher temperatures as well | 10°C to 80°C (adhesive joints used for joints can be used only up to 60°C) | -8°C to 95°C |
| CAPEX Costing | Higher than PPR-C | Higher than PPR-C | Very Low CAPEX Costing |
| OPEX Costing | Higher than PPR-C because of high maintenance | Higher than PPR-C | Very Low OPEX Costing because of negligible maintenance |
| Installation Time | Very high because of welding joints and more manpower required | Negligible as solution-based joints | Low because of socket fusion jointing |

WELDING PROCESS
Cutting
• Cut the pipe at right angle to its axis using burr-free cutter
• Ensure that pipe is free from burrs or cutting chips
• Clean the pipe & fitting perfectly before welding.
• Mark welding depth at the end of pipe
Heating
• Mount the suitable Dies (Socket and Pucnh) on heating element of welding machine according to the diameter of pipe and fitting to be welded
• Connect the welding machine to 220 Volts A.C. power supply d
• Select 260 C temperature on the welding machine hermostat d
• Wait for reaching the required working temperature d
• Insert the pipe and the fitting in the Dies (i.e. Socket and Punch respectively) by exerting light pressure d
• Heat both pipe & fitting as per the size and time given in the following table
Welding
• After heating, quickly insert pipe into the fitting by exerting light pressure
• Any misalignment should be corrected immediately after insertion to avoid any stress in the weld. This type of connection ensures perfect sealing even under the hard working conditions.
Note :
1. Avoid air draughts during welding to avoid stress in the welds.
2. During site welding, keep the welding set at a right angle to the pipe and fitting in order to avoid partial welding
