What is Socket 25mm Q-Therm PPRc ?
Specifications
The following table outlines the key technical specifications for the Socket 25mm Q-Therm PPRc PN 25, based on standard PPRc standards (DIN 8077/8078) and Q-Therm product details:
| Parameter | Details |
|---|---|
| Nominal Diameter (OD) | 25mm |
| Pressure Rating (PN) | 25 (25 bar at 20°C) |
| Material | Polypropylene Random Copolymer (PP-R Type 3) |
| Temperature Range | -20°C to +95°C (suitable for hot and cold water; derates with temperature) |
| Connection Type | Socket fusion (heat welding) |
| Standards Compliance | DIN 8077/8078, ISO 15874 |
| Color | Typically green (for hot water) or gray (for cold water variants) |
| Service Life | Minimum 50 years under PN 25 at 20°C |
| Weight (approx.) | 0.05–0.08 kg (lightweight for easy handling) |
| Dimensions | Socket depth: ~25–30mm; Outer diameter compatibility: 25mm pipes |
Note: Pressure rating decreases with temperature (e.g., ~10 bar at 60°C, ~5 bar at 80°C). Always refer to the manufacturer’s pressure-temperature chart for precise derating.
Usage
This socket fitting is primarily used for joining straight sections of 25mm PPRc pipes in hot and cold water distribution systems. It is ideal for:
- Domestic and Commercial Plumbing: Hot/cold potable water supply in residential buildings, apartments, and offices.
- Heating and Cooling Systems: Radiant floor heating, underfloor heating, and chilled water piping.
- Industrial Applications: Compressed air lines, aggressive fluid transport, and non-potable water systems where chemical resistance is needed.
- High-Rise Constructions: Commonly specified in Karachi and other regions for its reliability in multi-story buildings.
It ensures hygienic, leak-proof joints without the need for additional sealants, maintaining water purity and preventing bacterial growth due to its smooth inner surface. Not recommended for outdoor exposure without UV protection or aluminum-layered variants.
Installation
Installation of the Socket 25mm Q-Therm PPRc PN 25 requires socket fusion welding using a specialized PPR welding machine. Follow these steps for a secure, professional joint:
- Preparation:
- Cut the pipe ends squarely using a PPR pipe cutter to ensure a clean, perpendicular edge.
- Clean the pipe ends and socket inner surface with alcohol or a dry cloth to remove dirt, grease, or moisture.
- Measure and mark the insertion depth on the pipe (typically 25–30mm for 25mm socket).
- Heating:
- Preheat the fusion machine to the recommended temperature: 260–280°C (standard for PPRc).
- Insert the pipe end into the machine’s heating bush and the socket into the corresponding heating socket simultaneously for 10–15 seconds (time varies by ambient temperature; use a timer).
- Fusion:
- Quickly remove both components from the heater and immediately insert the heated pipe end into the socket.
- Apply even pressure (hold for 10–20 seconds) to achieve a uniform bead formation around the joint, ensuring full insertion to the marked depth.
- Allow the joint to cool undisturbed for at least 10–15 minutes (longer in cold conditions) before handling.
- Testing and Best Practices:
- After assembly, pressure-test the system at 1.5 times the operating pressure for 1–2 hours.
- Use protective sleeves for pipes in walls or floors to accommodate thermal expansion (PPRc expansion coefficient: ~0.15mm/m/°C).
- Avoid bending pipes sharply (minimum bend radius: 5x diameter); use elbows for turns.
- Tools required: PPR fusion machine, cutter, chamfering tool, and calibration gauges.
- Safety: Wear gloves and eye protection; work in a well-ventilated area.
