What is Reducing Tee 75x50mm EG PPRc ?

 

A Reducing Tee 75x50mm EG PPRc PN25 is a high-performance piping component used to create a branch in a main line.¹ In this specific configuration, it connects a 75mm main pipeline to a 50mm branch line, allowing for a controlled transition in fluid volume and pressure.

The PN25 rating indicates it is built for extreme pressure, far exceeding standard residential requirements, which makes it ideal for heavy-duty HVAC and commercial water systems.

1. General Description

• Material: Polypropylene Random Copolymer (PPRc) Type 3.³ This material is biologically neutral, corrosion-resistant, and maintains its strength at high temperatures.

• Brand (EG): Often associated with Euro Gulf or similar high-specification manufacturers from the Saudi/Middle Eastern region, known for strict adherence to international quality standards.

• Function: It acts as a three-way junction where the “run” (straight through) is 75mm and the “branch” (offshoot) is 50mm.

2. Technical Specifications

This fitting is typically manufactured to meet DIN 8077/8078 or ISO 15874 standards.⁵

3. Usage & Applications

The PN25 rating makes this tee suitable for the most demanding environments:

• HVAC Systems: Used in Chilled Water Risers and central air conditioning networks. The thick walls (PN25) provide the necessary safety margin for the high static pressures found in multi-story buildings.

• Water Supply: Ideal for Main Risers in commercial buildings where a 75mm main line needs to feed a 50mm sub-main or floor distribution line.

• Industrial Plants: Suitable for compressed air lines and the transport of certain chemical fluids due to its high chemical resistance.

4. Installation & Fusion Process

PPRc fittings are joined through Heat Fusion, which creates a permanent, leak-proof bond.

1. Cutting: Use a professional PPR pipe cutter to ensure a square, clean cut on both the 75mm and 50mm pipes.

2. Cleaning: Wipe the pipe ends and the internal sockets of the tee with a clean cloth. Any dust or grease can compromise the weld.

3. Heating: Use a socket fusion machine set to 260°C.

   • 75mm end: Heat for approx. 30 seconds.

   • 50mm branch: Heat for approx. 18 seconds

4. Joining: Push the pipe into the fitting socket until it reaches the specified depth mark. Do not twist the pipe during insertion.

5. Cooling: Hold the joint steady for about 30–40 seconds. Allow at least 10 minutes for the 75mm joint to cool completely before applying any mechanical stress.

5. Key Advantages

• Leak-Proof: The fusion process makes the pipe and fitting a single continuous piece of material.

• High Insulation: PPRc has low thermal conductivity (¹²$0.24$ W/mK), which reduces heat loss in hot water systems and prevents condensation in chilled water HVAC systems.

• Non-Toxic: It is completely safe for potable (drinking) water and does not change the taste or odor of the water.¹⁴
