Design & Function:

• Standard Coupling (Register Coupling): Provides a secure, permanent connection between two PPR pipes, ensuring proper alignment and flow continuity.

• Repair Coupling (Slip Coupling): Features extended sockets without central stops, allowing the coupling to slide along the pipe for fast repair or replacement without full system disassembly.

Material:

• PPR (Polypropylene Random Copolymer): Lightweight, hygienic, and resistant to high impact and temperature variations.

• Color Coding:

  • Black: Suitable for outdoor installations with UV protection.

  • Green: Intended for indoor potable water systems.

Standards Compliance:

• ISO 15874: Polypropylene piping systems for hot and cold water installations, ensuring mechanical strength, thermal resistance, and pressure ratings.

Performance Characteristics:

• Pressure Ratings: PN10, PN16, or PN20 depending on size and application.

• Temperature Range: Continuous operation up to 70 °C; short-term peaks up to 90 °C.

• Sealing: Jointed by socket fusion or electrofusion for reliable, leak-free connections.

• Service Life: Over 50 years under standard operating conditions.

Applications:

• Hot and cold potable water distribution networks.

• Indoor plumbing (green) and outdoor piping systems with UV exposure (black).

• Irrigation and industrial piping.

• Pipeline repair and extension without system redesign.

Installation:

• Standard Couplings: Socket-fused or electrofusion welded for permanent, aligned joints.

• Repair Couplings: Slide over the prepared pipe section and fuse for rapid restoration of service.

Key Benefits:

• Durable, hygienic, and corrosion-resistant.

• Color-coded for optimal indoor/outdoor application.

• Quick and efficient repair without shutting down the system.

• Fully compliant with ISO 15874 for safety, reliability, and long-term performance.
