What is Tee 40mm RAKtherm PPRc ?

 

The RAKtherm 40mm Equal Tee (PN25) is a premium, three-way fusion-welded piping component manufactured by Gulf Plastic Industries in the UAE. Designed to create a $90^\circ$ branch line in a 40mm PPR-C piping network, this specific fitting features a PN25 (Pressure Nominal 25 bar) rating. This makes it a heavy-duty, thick-walled component engineered to withstand extreme thermal and mechanical stresses, far outperforming standard PN16 or PN20 fittings.

Key Performance Characteristics:

• Temperature Range: Safely operates from -20°C up to 95°C (making it ideal for boiling hot water and HVAC chilling cycles).

• Chemical Resistance: Highly inert; completely resistant to scaling, corrosion, and electrochemical degradation.

• Low Thermal Conductivity: At $0.24 \text{ W/mK}$, it reduces heat loss in hot water lines and limits condensation on chilled HVAC lines.

3. Usage & Applications

Because of its heavy-walled PN25 construction, this 40mm tee is deployed in high-demand, high-pressure environments:

• HVAC Systems: Used for chilled water cooling loops and dual-temperature hydronic heating systems.

• Hot & Cold Water Ring Mains: Ideal for commercial riser structures, residential complexes, and industrial water distribution networks.

• Boiler & Solar Heater Plumbing: Acts as a primary manifold or distribution branch coming directly out of high-temperature heat exchangers.

• High-Pressure Compressed Air: Suitable for industrial compressed air lines where structural rigidity and zero-leak joints are mandatory.

4. Installation & Polyfusion Welding Guidelines

To maintain the structural integrity of a PN25 system, the 40mm Tee must be joined using correct socket fusion protocols.

Fusion Parameters for 40mm PPR-C:

• Welding Tool Temperature: $260^\circ\text{C} \pm 10^\circ\text{C}$

• Heating Time: 12 seconds (The time the pipe and tee sit on the welding dies)

• Processing/Assembly Time: 6 seconds max (Time allowed to push the parts together)

• Cooling Time: 4 minutes (Must remain undisturbed to fully cure)

Step-by-Step Installation Steps:

1. Square Cut: Cut the 40mm PPR-C pipe perfectly perpendicular to its axis using a sharp pipe cutter.

2. Clean & Mark: Clean both the inside of the tee socket and the outside of the pipe. Mark a fusion depth of approximately 20.5 mm on the pipe end to avoid over-inserting (which chokes the internal water flow).

3. Simultaneous Heating: Push both the 40mm pipe and the RAKtherm tee onto the $260^\circ\text{C}$ welding matrix simultaneously. Hold for exactly 12 seconds.

4. Joint Alignment: Pull them straight off the welding tool and push the pipe firmly into the tee until it reaches the marked depth line. Crucial: Do not rotate or twist the pipe during insertion, as this introduces micro-air gaps in the molten polymer.

5. Cool Down: Hold the joint steady for at least 6 seconds. Allow it to air-cool completely for 4 minutes before applying any physical stress or alignment pressure.
