IFAN High-Durable PPR Pipe Fittings

Standard ratings: PN10, PN16, PN20
PPR Pipe Fittings typically have PN10, PN16, or PN20 ratings. PN10 means 10 bar (145 psi) at 20°C. PN16 means 16 bar (232 psi) at 20°C. PN20 means 20 bar (290 psi) at 20°C. Example: PN20 for high-pressure systems.

Pressure rating at higher temperatures
Pressure ratings decrease at higher temperatures. At 60°C, PN20 drops to 10 bar. At 80°C, it drops further. PPR Pipe Fittings require derating for hot water.

Pressure rating by pipe size
Pressure ratings may vary by pipe size. Smaller diameters often have higher ratings. Larger diameters may have lower ratings. PPR Pipe Fittings ratings are size-specific.

SDR and pressure rating
Pressure rating relates to SDR. Lower SDR means thicker walls and higher pressure. PPR Pipe Fittings with lower SDR handle higher pressure. Example: SDR 6 for PN20.

Example: residential plumbing
A home uses PPR Pipe Fittings for water supply. The fittings are PN20 rated. The system handles 10 bar. Example: a reliable water supply system.

Example: commercial building
A commercial building uses PPR Pipe Fittings. The fittings are PN16 rated. The system handles 8 bar. Example: a reliable commercial system.

Example: industrial piping
A factory uses PPR Pipe Fittings. The fittings are PN20 rated. The system handles 10 bar. Example: a durable industrial system.

Pressure testing
PPR Pipe Fittings are pressure-tested. They are tested at 1.5 times the working pressure. This ensures safety. Example: a fitting tested at 30 bar for PN20.

Burst pressure
Burst pressure is much higher than working pressure. It is typically 3-4 times the working pressure. PPR Pipe Fittings have large safety factors. Example: a PN20 fitting bursts at 60-80 bar.

Manufacturer specifications
Always check the manufacturer's pressure rating. Ratings vary by size and temperature. PPR Pipe Fittings should be used per guidelines.

Final pressure rating summary
PPR Pipe Fittings have PN10, PN16, or PN20 ratings. Ratings decrease at higher temperatures. Smaller sizes handle higher pressures. SDR affects the pressure rating. PPR Pipe Fittings are available for many pressure ranges. Example: choose the right rating for your system.
