What is Reducing Tee 50x40mm EG PPRc ?

 

Description

A Reducing Tee 50x40mm EG PPRc PN25 is a pipe fitting made from Polypropylene Random Copolymer (PPR or PPRc), a durable thermoplastic material. It is a reducing tee, meaning it has three outlets: two of larger diameter (50mm) for the main run and one smaller branch outlet (40mm) at a 90-degree angle. This allows branching off a smaller pipe from a larger main line while maintaining flow direction.

• PPRc: Stands for Polypropylene Random Copolymer Type 3, known for its random molecular structure that provides excellent heat resistance, chemical resistance, and hygiene (no taste/odor impartation to water).
• PN25: Pressure rating of 25 bar (2.5 MPa), suitable for high-pressure systems.
• EG: Likely refers to “Electrofusion Compatible” or a specific brand/marking (common in some regions for PPR fittings); PPR fittings are plastic, not galvanized metal.
• Colors: Typically green, white, or grey.

It is commonly used in modern plumbing as a replacement for galvanized steel pipes due to its corrosion resistance, lightweight nature, and long lifespan.

Specifications

• Material: Polypropylene Random Copolymer (PP-R Type 3)
• Sizes: Main run: 50mm outer diameter × 50mm; Branch: 40mm outer diameter (notation 50x40x50mm or similar)
• Pressure Rating: PN25 (25 bar at 20°C; suitable for up to ~10 bar at 95°C hot water)
• Temperature Range: -20°C to 95°C (max transient up to 110°C)
• Standards: Typically complies with DIN 8077/8078, ISO 15874, or equivalents (e.g., DVGW, TS 9937)
• Connection Type: Socket fusion (heat welding)
• Service Life: 50+ years under normal conditions (e.g., 20°C at rated pressure)
• Properties:
  • Non-toxic, hygienic, and suitable for potable water
  • High resistance to chemicals, impact, and scaling
  • Low thermal conductivity (good insulation)
  • Smooth inner surface (low friction loss, high flow rate)

sage and Applications

This fitting is primarily used in hot and cold water supply systems, including:

• Residential and commercial potable water distribution
• Heating systems (radiators, underfloor heating)
• HVAC (heating, ventilation, and air conditioning) chilled/hot water loops
• Industrial fluid transport (non-aggressive chemicals, compressed air)
• Agricultural irrigation

It is ideal where a branch line needs lower flow/pressure (e.g., from a 50mm main to a 40mm fixture supply). Not suitable for gas lines or extreme chemicals.

Advantages over metal fittings:

• Corrosion/rust-free
• Lightweight and easy to handle
• Lower installation costs
• Recyclable

Installation

PPR fittings like this reducing tee are installed via socket fusion welding (hot melt connection), creating a permanent, leak-proof joint stronger than the pipe itself.

Step-by-Step Guide:

1. Prepare Tools: PPR pipe cutter, fusion welding machine (with correct sockets for 50mm and 40mm), deburring tool, marker, and level.
2. Cut Pipes: Cut pipes squarely and cleanly to length. Deburr and chamfer edges.
3. Mark Depth: Mark insertion depth on pipe ends (per manufacturer chart; e.g., ~25-30mm for 50mm, ~20-25mm for 40mm).
4. Heat: Set welder to ~260°C (500°F). Insert pipe and fitting onto sockets simultaneously:
   • Heat smaller (40mm) side first if needed.
   • Typical times: 40mm ~12-15 seconds; 50mm ~18-25 seconds (varies by brand/machine).
5. Join: Remove from welder quickly, align straight, push together firmly with a slight twist (1/8 turn). Hold for 10-30 seconds.
6. Cool: Allow 5-10 minutes cooling before applying pressure or stress. Do not bend or force during cooling.
7. Test: Pressure test the system after full cooling.
