Hot & cold plumbing built to last 50 years.
Signet CPVC pipes and fittings to IS 15778 and ASTM D2846 — suitable for potable hot and cold water up to 93°C, certified and lead-free.
Why CPVC
10 reasons plumbers specify CPVC.
93°C Service Temperature
Safe for hot-water plumbing that copper and uPVC cannot handle.
50-Year Design Life
CPVC retains pressure and structural integrity over decades — outlasts the building.
Potable Water Safe
No lead, no heavy metals. IS 15778 and ASTM D2846 specify food-grade CPVC compound.
BIS IS 15778 Certified
Indian Standard for CPVC pipes and fittings — every batch tested and marked.
Corrosion & Scale Resistant
CPVC does not corrode, pit or develop scale deposits like metal alternatives.
Low Thermal Conductivity
Retains water temperature longer — reduced heat loss in hot-water runs.
Self-Extinguishing
CPVC is inherently flame-retardant — does not sustain fire once the ignition source is removed.
Chlorine & Chemical Resistant
Unaffected by municipal chlorinated water, dilute acids and alkalis.
Lighter than Metal
~1/6th the weight of copper — faster installation, lower labour cost on site.
Low Noise Transmission
Reduced water-hammer effect compared to metal pipes in pressurised systems.
Material Comparison
CPVC vs uPVC vs Metal — the full picture.
| Property | CPVC (Signet) | uPVC | Metal |
|---|---|---|---|
| Max service temperature | 93°C | 60°C | 150°C (copper) / 480°C (galv.) |
| Corrosion resistance | Excellent | Excellent | Poor (galvanised) / Moderate (copper) |
| Scale & pitting | None | None | Yes (galvanised) |
| Potable water safety | Yes — IS 15778 / ASTM D2846 | Yes (cold water only) | Copper: Yes; Galvanised: Risk of leaching |
| Weight (vs copper) | 1/6th | 1/6th | 1× |
| Thermal conductivity | 0.136 W/m·K (very low) | 0.16 W/m·K | 386 W/m·K (copper) |
| Design life | 50 years | 25–30 years | 15–25 years (galvanised) |
| Installation cost | Low (solvent cement) | Low (solvent cement) | High (threading / brazing) |
| Hot-water suitability | Yes | No | Yes (copper only) |
