What is Tee 75mm RAKtherm PPRc ?

 

Tee 75mm RAKtherm PPRc (or PPR/PPRC) PN25 is a polypropylene random copolymer (PP-R or PPRc) equal tee fitting (all three branches 75mm) manufactured by RAKtherm (Gulf Plastic and Converting Industries / Tahweel), based in Ras Al Khaimah, UAE.

RAKtherm is a major Middle Eastern producer of PPR piping systems using advanced German technology. These fittings (and matching pipes) are widely used for pressurized hot and cold water supply, HVAC systems, underfloor heating, and industrial fluid transport.

Description

• Material: High-quality PP-R (Polypropylene Random Copolymer), a thermoplastic known for excellent chemical resistance, durability, and safety for potable water (used in food/medical industries).
• Type: Equal Tee (T1-75 or similar art. no. in RAKtherm catalogs) — branches all the same diameter for branching or combining flows in a piping network.
• Color: Typically green (standard for RAKtherm PPRc).
• Design: Socket fusion type — designed for heat welding to matching 75mm PPR pipes. Smooth internal bore minimizes pressure drop and scaling.
• Key Benefits: Corrosion-free, lightweight, low thermal conductivity (reduces heat loss), hygienic, long service life (50+ years under normal conditions), and environmentally friendly (recyclable).

Specifications (Typical for RAKtherm PN25 Series)

• Nominal Diameter (DN/OD): 75mm outer diameter.
• Pressure Rating (PN25): 25 bar (2.5 MPa) at 20°C. Derates with temperature (e.g., lower at higher temps; suitable for hot water up to ~70–95°C depending on exact conditions and standards like DIN 8077/78).
• Wall Thickness: Matches PN25 (SDR 5 / S 2 series) pipes — thicker walls for high pressure/temperature resistance (exact fitting socket dimensions align with pipe OD and wall).
• Weight: Approximately 0.523 kg per piece (per RAKtherm catalog data for 75mm Equal Tee).
• Packing: Often 1 pc per unit (larger sizes like 75mm are sold individually or in small quantities).
• Standards: Conforms to DIN 8077/8078, ISO 15874, and other international norms for PPR systems. RAKtherm products undergo rigorous quality control.
• Temperature Range: Cold water to hot water (continuous up to 70°C, short-term peaks higher). Ideal for HVAC and domestic hot/cold supply.

Compatible with RAKtherm PN25 pipes (e.g., Series 2 solid PP-R PN25) and other fittings in the system (elbows, reducers, valves, etc.).

Installation (Socket Fusion Welding)

PPR fittings like this Tee are joined using socket fusion (heat welding), creating a homogeneous, leak-proof joint stronger than the pipe itself.

Basic Steps (always follow RAKtherm’s manual and use approved tools):

1. Cut pipe squarely with a pipe cutter; deburr and clean ends.
2. Use a socket fusion welding machine (with proper heating sockets for 75mm).
3. Heat the pipe end (outer) and fitting socket (inner) simultaneously to fusion temperature (~260°C).
4. Join quickly (push to full depth without twisting) and hold briefly.
5. Cool undisturbed (per manufacturer times — longer for larger diameters like 75mm).
6. Allow time before pressure testing (e.g., 1–2 hours after last weld).

• Use RAKtherm welding devices, tools, and clamps for best results.
• Account for thermal expansion in long runs (use supports, expansion loops).
• For HVAC/water supply: Proper alignment, supports, and insulation (especially hot lines) are essential.

Safety/Notes: Follow local codes, pressure test the system, and avoid over-insertion or contamination. Professional installation recommended for larger sizes.

Usage

• Primary Applications: Hot & cold potable water supply, HVAC (heating, ventilation, air conditioning) distribution, radiator/underfloor heating, industrial process lines (non-aggressive fluids).
• Advantages in HVAC/Water Supply: Excellent for high-temperature/pressure demands, no corrosion or scaling, fast installation, and reliable long-term performance in residential, commercial, and industrial buildings.
• Limitations: Not for gas or highly aggressive chemicals without verification; derate pressure for very high temps.
