What is Reducing Tee 63x25mm EG PPRc ?

 

A Reducing Tee 63x25mm EG PPRc PN 25 is a plumbing fitting used in piping systems for heating, ventilation, air conditioning (HVAC), and water supply applications. It is a type of tee connector that allows for branching in pipelines while reducing the pipe diameter from 63mm to 25mm. The “EG” likely refers to “Electrofusion” or a specific brand/model designation (e.g., from manufacturers like Upon or or similar), indicating compatibility with electrofusion welding for secure joints. Made from PPRc (Polypropylene Random Copolymer), it’s a durable, corrosion-resistant plastic material ideal for potable water, hot water, and heating systems. This fitting ensures a smooth transition in flow, minimizing pressure loss and turbulence, and is commonly used to connect smaller branches (e.g., 25mm pipes) to larger main lines (63mm pipes) in residential, commercial, or industrial setups.

Specifications

• Material: PPRc (Polypropylene Random Copolymer) – a thermoplastic polymer known for its high chemical resistance, thermal stability, and low thermal conductivity. It complies with standards like DIN 8077/8078 or ISO 15874 for PPR piping systems.
• Dimensions: 63mm (main inlet/outlet) x 25mm (reduced branch), with standard wall thicknesses for PN 25 rating (typically around 5.8mm for 63mm and 2.3mm for 25mm pipes, based on SDR 7.4 classification).
• Pressure Rating: PN 25 (Nominal Pressure 25 bar or ~362 psi at 20°C), suitable for high-pressure applications up to 10 bar at 90°C or 25 bar at 20°C, as per manufacturer guidelines (e.g., from brands like Waving or Rehau).
• Temperature Range: -20°C to +95°C, making it suitable for both cold and hot water systems, including underfloor heating.
• Standards Compliance: Meets EN ISO 15874, DIN 16962, or equivalent for PPR fittings, ensuring safety for potable water (NSF/ANSI 61 certified in some regions). It has a smooth internal surface (roughness <0.01mm) to prevent scaling and bacterial growth.
• Weight and Packaging: Lightweight (approx. 0.1-0.2 kg per piece), often sold in packs of 10-50 for bulk installations.
• Color: Typically white or gray for easy identification in plumbing systems.
• Additional Features: Electrofusion socket ends for quick, leak-proof connections; UV-resistant for outdoor use if specified.

These specs are based on standard PPRc fitting data from manufacturers like Upon or, Waving, or similar, ensuring reliability in systems handling up to 25 bar pressure without deformation.

Installation

Installation involves electrofusion welding, a process that creates a permanent, homogeneous joint. Here’s a step-by-step guide:

1. Preparation: Ensure pipes and fittings are clean, dry, and free of debris. Cut PPR pipes to length using a pipe cutter for square ends. Chamfer the pipe ends slightly for better fusion.
2. Alignment: Insert the pipe into the tee’s socket (63mm for main line, 25mm for branch). Use alignment tools if needed to ensure proper depth (marked on the fitting).
3. Electrofusion: Use an electrofusion machine (e.g., a welder like those from Rosenberger or similar). Set the machine to the fitting’s barcode parameters (voltage, time, and current). The machine heats the fitting’s embedded coils, melting the PPRc surfaces to form a bond. Typical fusion time is 10-30 seconds depending on size and ambient temperature.
4. Cooling: Allow the joint to cool for 5-10 minutes before handling or pressure testing. Avoid stressing the joint during cooling.
5. Testing: Pressure test the system to PN 25 (e.g., using water at 1.5x working pressure) to check for leaks. Follow local plumbing codes (e.g., BS 6700 in the UK or UPC in the US).

Tools required: Electrofusion welder, pipe cutter, chamfering tool, and safety gear. Installation should be done by certified plumbers to avoid voids or weak joints, which could lead to failures under pressure.

Usage

This fitting is primarily used in HVAC and water supply systems for branching and reducing pipe sizes, such as:

• Water Supply: Connecting smaller distribution lines (25mm) to main supply pipes (63mm) in buildings, ensuring efficient flow in potable water networks.
• HVAC: In heating circuits, like radiator loops or underfloor heating, where it allows for size reduction to match appliance requirements without significant pressure drop.
• Applications: Ideal for residential plumbing (e.g., kitchen/bathroom setups), commercial buildings, or industrial systems. It handles both hot and cold fluids, resists corrosion from chemicals or minerals in water, and has a long lifespan (up to 50+ years with proper installation).
