What is Male Socket 110×4″ RAKtherm PPRc ?

 

RAKtherm PPRc Male Socket (Transition Piece Round-Male) 110mm x 4″ PN 25, engineered by Gulf Plastic and Converting Industries (Tahweel) in the UAE.

1. Description & Overview Male Socket 110×4″ RAKtherm PPRc

The RAKtherm $110\text{mm} \times 4″$ Male Socket is a heavy-duty transition fitting designed to securely bridge large-bore PPRc thermoplastic piping networks with metallic piping components, valves, pumps, or HVAC equipment.

• Dual-Material Design: It features a premium Polypropylene Random Copolymer (PPRc) body permanently over-molded onto a heavy-duty, precision-machined brass insert with a $4″$ male BSP/NPT thread.

• High Torque & Leak Resistance: The internal brass insert is specifically engineered with deep anchoring ribs to withstand high mechanical tightening torque and eliminate rotational slippage or thermal bypass leaks under extreme temperature cycling.

3. Key Usage & Applications

Because of its massive size ($110\text{mm} \times 4″$) and structural PN 25 rating, this fitting is primarily used in commercial, industrial, and large-scale mechanical infrastructure rather than standard residential bathrooms.

• HVAC Mechanical Rooms: Connecting main chilled/hot water distribution loops from central chillers, cooling towers, and boilers to multi-inch flanged manifolds or headers.

• Chilled Water & District Cooling Systems: Excellent for condensation-free cooling circuits due to PPRc’s low thermal conductivity ($0.23\text{ W/m}\cdot\text{K}$).

• Commercial Hot & Cold Water Risers: Serving as the main connection point for primary risers in high-rise complexes, hotels, and hospitals.

• Industrial Fluid Transport: Ideal for aggressive fluid or chemical transport due to the high chemical resistance of PPR Type 3.

4. Installation Guidelines (Step-by-Step)

Due to the $110\text{mm}$ large diameter, specialized equipment and precise handling are mandatory to guarantee a structural joint.

Step 1: Tool Preparation

• Utilize a heavy-duty mechanical welding machine equipped with a calibrated $110\text{mm}$ heating die.

• Set the welding thermostat strictly between $260^\circ\text{C}$ and $270^\circ\text{C}$.

Step 2: Cutting & Cleaning

• Cut the $110\text{mm}$ pipe perfectly square using a professional pipe cutter.

• Important: If using RAKtherm Stabi (Aluminum composite) or Fiber-reinforced pipes, ensure the outer layer is cleanly peeled/chamfered back to expose the virgin welding layer using the appropriate RAKtherm peeling tool.

• Clean both the pipe exterior and the socket interior with a lint-free cloth and isopropyl alcohol.

 3: Heating Interval (Critical Large-Diameter Timing)

• Push the $110\text{mm}$ pipe end and the socket fitting into the heating tools simultaneously without rotating.

• Heating Time: Hold for a minimum of $40\text{ seconds}$ once fully inserted into the welding die.

4: Fusion Joining

• Remove the pipe and fitting from the heating tool and join them smoothly without twisting.

• Hold the joint firmly in place for at least $10\text{ seconds}$ to allow initial fusion stability.

• Allow a full cooling period of at least $8\text{ minutes}$ before subjecting the joint to any mechanical stress.

5: Threaded Connection (4″ Brass Side)

• Apply a high-quality thread sealant (such as PTFE tape or appropriate anaerobic pipe dope) to the $4″$ male brass thread.

• Thread into the female counterpart by hand first, then tighten using an industrial strap wrench or pipe wrench. Do not over-torque, as the specialized brass insert is optimized to seal tightly without requiring excessive force.
