What is Elbow male 32×3/4″ Brass RAKtherm PPRc ?

 

The RAKtherm PPRc Male Elbow ($32 \text{ mm} \times 3/4″$) PN 25 is a premium-grade, heavy-duty transition fitting manufactured by RAKtherm in the United Arab Emirates (UAE).

 The PN 25 pressure rating makes it the gold standard for demanding hot/cold water distribution and HVAC applications.

1. Description & Core Features

The fitting utilizes a 90-degree elbow profile to make sharp directional changes in tight spaces. It is constructed using a two-part hybrid design:

  • Premium PPRc Body: Molded from high-molecular-weight Polypropylene Random Copolymer (Type 3). It is chemically inert, non-toxic, and maintains structural integrity at elevated temperatures.

3. Recommended Applications

Thanks to its heavy-wall PN 25 profile and corrosion-resistant brass threads, this fitting is ideal for:

  1. HVAC & Chilled Water Piping: Excellent thermal insulation performance limits condensation formation in chilled water fan coil units (FCUs) and air handling units (AHUs).

  2. High-Pressure Hot & Cold Potable Water Systems: Retains high mechanical strength at continuous hot water temperatures up to $70^\circ\text{C}$.

  3. Boiler Room & Radiator Connections: Seamlessly transitions from main PPRc supply risers directly into copper/brass manifold systems.

  4. Industrial Fluid Networks: High chemical resistance makes it suitable for aggressive fluid transport in commercial facilities.

4. Installation & Welding Guidelines

To ensure a permanent, leak-proof joint, the socket fusion must be executed with calibrated welding tools.

1.Pipe Prep & Depth Marking:

Cut the $32\text{ mm}$ PPRc pipe square using professional pipe cutters. Measure and mark a fusion insertion depth of $18\text{ mm}$ on the pipe end to avoid over-pushing (which causes internal restriction) or under-pushing (which weakens the joint).

2.Heating Cycle:

Ensure your PPR welding machine is heated to $260^\circ\text{C}$. Push the $32\text{ mm}$ pipe and the $32\text{ mm}$ side of the elbow simultaneously into the welding dies. Heat them for a strict dwell time of 8 seconds.

3.Fusion Joint Connection:

Pull the components off the welding dies and smoothly push the pipe into the fitting socket without twisting. Hold the joint firmly in place for 6 seconds to allow the materials to fuse. Allow it to cool naturally for at least 4 minutes before handling.

4.Thread Connection:

Wrap the $3/4″$ male brass thread with high-density Teflon tape (PTFE) or thread sealing paste. Tighten the brass joint into the mating female fixture using an open-ended wrench or strap wrench. Avoid over-torqueing to prevent damage to the mating thread.

 

5. Usage Advantages

  • No Scaling or Calcification: The smooth inner PPRc surface limits friction loss, maintaining a constant flow rate over decades.

  • No Galvanic Corrosion: Unlike fully metallic lines, the PPRc-to-brass transition prevents localized galvanic corrosion loops when connecting mixed metals in HVAC networks.

  • Low Thermal Conductivity: Minimizes heat loss in central heating loops, eliminating the need for complex, bulky external insulation on the fittings.
