What is Female Socket 63×2″ DADEX PPRc ?

 

Product Overview

The Female Socket 63×2″ DADEX PPRc PN 25 is a specialized fitting from the DADEX brand, designed for polypropylene random copolymer (PPRc) piping systems. It’s used in HVAC (heating, ventilation, and air conditioning) applications and hot/cold water supply lines. The “63×2″” designation indicates a 63mm nominal diameter (DN63) PPRc socket on one end and a 2-inch (50.8mm) female threaded connection on the other, allowing transition between PPRc pipes and threaded components like valves or pumps. This fitting ensures leak-proof, durable connections in plumbing systems.

Description

• Material: Polypropylene Random Copolymer (PPRc), a thermoplastic polymer known for its corrosion resistance, smooth inner surface (reducing scaling), and ability to handle both hot and cold fluids without degradation.
• Design: Features a female socket for fusion welding to PPRc pipes and a 2-inch BSP (British Standard Pipe) female thread for screwing onto threaded male components. The PN 25 rating indicates it’s suitable for pressures up to 25 bar (362.5 psi) at 20°C, with temperature resistance up to 95°C for hot water systems.
• Key Features: Lightweight, easy to install, non-toxic (food-grade compliant), and resistant to chemical corrosion. It’s part of the DADEX PPRc system, which is widely used in Europe and Asia for reliable, long-term plumbing solutions.
• Color: Typically white or gray, with branding for identification.

This fitting is ideal for transitioning from PPRc piping to metal or other threaded systems in residential, commercial, or industrial setups.

Specifications

• Nominal Diameter: 63mm (PPRc side), 2″ (threaded side).
• Pressure Rating: PN 25 (25 bar at 20°C; derates to lower pressures at higher temperatures, e.g., 10 bar at 95°C).
• Temperature Range: -20°C to +95°C (suitable for cold water, hot water up to 95°C, and HVAC fluids).
• Thread Standard: BSP (G 2″) female thread, compliant with ISO 228-1.
• Dimensions:
  • Length: Approximately 100-120mm (varies by manufacturer).
  • Socket Depth: 50-60mm for fusion welding.
• Standards Compliance: Meets DIN 8077/8078 for PPR pipes/fittings, ISO 15874 for PPR systems, and CE marking for safety in EU markets.
• Burst Pressure: Up to 75 bar (tested under controlled conditions).
• Weight: Around 200-300g, depending on exact design.
• Certifications: Often includes WRAS (Water Regulations Advisory Scheme) approval for potable water use.

These specs ensure the fitting handles typical HVAC loads (e.g., radiator systems) and water supply pressures without failure.

Installation

Installation requires basic plumbing tools and follows PPRc fusion welding standards for the socket end and threading for the female end. Always wear safety gear and ensure the system is depressurized.

1. Preparation:

   • Cut the PPRc pipe to length using a pipe cutter for a clean, square end.
   • Deburr the pipe edges and clean both the pipe and socket with a PPR cleaner to remove oils or debris.

2. Fusion Welding (PPRc Side):

   • Heat the socket and pipe end with a PPR welding machine (set to 260-280°C for PN 25 material).
   • Insert the heated pipe into the socket and hold for 10-15 seconds (rotation-free) until cooled. Allow 5-10 minutes for full solidification.
   • Avoid over-heating to prevent deformation.

3. Threaded Connection (Female Side):

   • Apply PTFE tape or thread sealant to the male thread of the connecting component (e.g., valve).
   • Screw the component into the 2″ female thread by hand, then tighten with a wrench (torque to 20-30 Nm, depending on size—check manufacturer guidelines to avoid cracking).
   • Ensure alignment to prevent stress on the joint.

4. Testing:

   • Pressure-test the system at 1.5x working pressure (e.g., 37.5 bar for PN 25) for leaks.
   • For HVAC, insulate joints to prevent condensation.

Installation time: 10-20 minutes per fitting. Follow DADEX manuals or local plumbing codes (e.g., BS 6700 in the UK) for best practices. Not suitable for direct burial without protection.

Usage

• Primary Applications:
  • Hot and cold water supply in buildings (e.g., connecting PPRc risers to threaded faucets or pumps).
  • HVAC systems, such as radiator loops, underfloor heating, or chilled water lines, where it bridges PPRc pipes to metal valves or manifolds.
• Advantages: Reduces installation time compared to metal fittings, minimizes noise from water hammer, and maintains flow efficiency due to smooth bore.
• Limitations: Not for outdoor exposure without UV protection; avoid use with aggressive chemicals (e.g., strong acids). Maximum flow velocity: 2-3 m/s to prevent erosion.
• Maintenance: Inspect annually for leaks; replace if damaged. Compatible with DADEX PPRc pipes, elbows, and tees for full system integration.
