MS Heavy Class vs CPVC for fire systems
Most modern Indian fire system designs blend MS Heavy Class with CPVC - MS for the high-pressure riser and hydrant network, CPVC for the sprinkler branches inside conditioned spaces. The table summarises the tradeoffs.
| Factor | MS Heavy Class | CPVC |
|---|---|---|
| Temperature rating | -10 °C to +250 °C | -10 °C to +93 °C |
| Pressure rating | 20 kg/cm² | 12 kg/cm² @ 23 °C |
| Joint method | Welded or grooved (Victaulic) | Solvent welded |
| Standard | IS 1239 HC + IS 13039 | ASTM F442 + ASTM F493 |
| UL listing | Optional (LPCB common in India) | UL Listed (US standard) |
| Indian govt fire NOC | Yes | Yes (since 2016) |
| RP supply | Stock | Not stocked |
Selection guidance: government tenders and industrial fire systems default to MS Heavy Class; commercial high-rise sprinkler branches commonly use CPVC; mixed designs use MS HC for risers and hydrants with CPVC for sprinkler distribution. We supply the MS Heavy Class side off the shelf.
