Q-therm PPRc pipes and fittings , Food Grade, Plumbing Materials. PN 25 imported from UAE for hot and cold water distributor in Pakistan 0322-3540656
What is Union 40mm Q-Therm PPRc ?
Q-Therm’s PN 25 rating makes it suitable for high-pressure environments, outperforming lower PN-rated systems in multi-story buildings or systems with elevated temperatures. The imported UAE origin ensures compliance with international quality standards, making it a preferred choice in regions like the Middle East, South Asia, and beyond for reliable, long-term performance.
Specifications
The following table outlines the key specifications for the Union 40mm Q-Therm PPRc PN 25:
| Parameter | Details |
|---|---|
| Size (Nominal Diameter) | 40mm (outer diameter compatibility) |
| Material | Polypropylene Random Copolymer (PPRc Type 3), food-grade, virgin raw material with up to 10% recycled content (does not affect quality) |
| Pressure Rating (PN) | PN 25 (25 bar / 362.5 psi at 20°C) |
| Standard Dimension Ratio (SDR) | SDR 6 (for high-pressure applications) |
| Temperature Range | -20°C to +95°C (suitable for both hot and cold water; pressure derates at higher temperatures, e.g., ~5 bar at 95°C) |
| Length per Fitting | Approximately 100-120mm (varies slightly by design; not a straight pipe length) |
| Color | Green (standard for hot water lines; grey or white options may be available) |
| Connection Type | Socket fusion welding (heat fusion for permanent joints); threaded nut for disassembly |
| Standards Compliance | DIN 8077/8078 (German standards for PPR pipes and fittings), ISO 15874 (international standard for plastic piping systems for hot and cold water) |
| Warranty/Lifespan | 50 years under normal operating conditions (PN 25 at 20°C) |
| Weight (Approximate) | 0.15-0.20 kg per unit |
| Other Features | Smooth inner surface for low flow resistance; high chemical resistance; UV stabilized for limited outdoor exposure; aluminum fiber-coated variants available in the system for enhanced stiffness |
Note: Pressure ratings decrease with temperature (e.g., PN 20 at 60°C, PN 10 at 80°C). Always consult the manufacturer’s pressure-temperature chart for precise derating.
Usage
This union fitting is primarily used in plumbing systems for hot and cold water distribution, where easy maintenance or future modifications are required. It is ideal for:
- Hot and Cold Water Supply: In residential, commercial, and industrial buildings for potable water lines, ensuring hygienic transport without contamination.
- Heating and Cooling Systems: Central heating, underfloor heating, radiators, and air-conditioning/chiller water distribution due to its thermal stability and low thermal expansion.
- Straight-Line Connections: Joining two 40mm PPRc pipes end-to-end, particularly in areas needing occasional access (e.g., for repairs or inspections), as the union allows disconnection without specialized tools beyond the initial fusion welder.
- Installation Guidelines: Use socket fusion welding at 260-280°C for 10-15 seconds (depending on ambient conditions). Compatible with Q-Therm pipes (normal or aluminum-stabilized). Not recommended for gas or highly corrosive fluids. Ensure proper support spacing (every 0.75-1m) to manage thermal expansion. It is suitable for indoor installations; for outdoor use, opt for UV-resistant or buried applications.
