What is Socket 50mm DADEX PPRc ?

 

A Socket 50 mm DADEX PPRc PN25 is a pipe fitting made of PPRc (Polypropylene Random Copolymer), designed to connect two PPRc pipes of 50 mm nominal diameter. It is called a socket because each end is shaped to accept the pipe end for jointing. The PN25 means it is rated for up to 25 bar nominal pressure, making it suitable for high-pressure hot and cold water systems as well as many HVAC applications.

• 50 mm – fits 50 mm (nominal) PPRc pipe.

• Socket – both ends receive pipe ends for fusion welding.

• DADEX PPRc – the brand/system (e.g., Dadex Polydex) of PPRc material piping.

• PN25 – pressure class 25 (approx. 25 bar nominal at 20 °C), suitable for hot water, cold water, and HVAC systems.

PPRc fittings like this are widely used in plumbing and HVAC piping because they provide strong, leak-proof joints through heat fusion welding, and the PPRc material itself is corrosion resistant and non-toxic.

📌 Material & Benefits

Material:

• Polypropylene Random Copolymer (PPRc) — a high-quality polymer used worldwide for piping systems.

Why PPRc?

• Corrosion & rust resistant — does not deteriorate from water chemistry.

• Hygienic & safe — no heavy metals; compliant with potable water standards in many regions.

• High thermal resistance — can safely carry hot water and heating fluids.

• Long service life — typically 50+ years under proper use.

• Low thermal conductivity — less heat loss vs metal piping.

DADEX Polydex PPRc systems also often include antimicrobial protection in the pipe/fitting material for extra hygiene in potable water systems.

📊 Typical Specifications

Note: Exact pressure/temperature performance may vary slightly by brand and regional standards, but PN25 is a high-pressure rating suitable for domestic, commercial, and industrial hot and cold water lines.

🔧 Where It’s Used

🏠 Hot & Cold Water Supply

• Domestic and commercial plumbing systems for potable water.

• Works with PPRc piping systems for both hot water (up to ~70 °C continuously) and cold water supply.

• Safe and non-toxic materials preserve taste and quality of drinking water.

🔥 HVAC (Heating, Ventilation & Air Conditioning)

• Hydronic heating systems (radiators, heat pumps, boiler loops).

• Cooling water distribution in chilled water systems (within rated temperature range).

• Can be used for looped circuits where high pressures and temperature swings occur.

🏭 Industrial & Specialty Services

• Suitable for many industrial fluids compatible with PPRc (e.g., non-aggressive chemicals).

• Compressed air lines (if rated for gaseous service up to the PN rating).

🧱 Installation & Welding

Tools Required:

• PPR fusion welding machine with heaters sized for 50 mm sockets

• Pipe cutter and deburring/chamfer tool

• Clean cloth or alcohol wipe

Installation Steps:

1. Measure & Cut:
   Cut the PPRc pipe squarely to the required length using a PPR pipe cutter.

2. Clean & Prepare:
   Remove any burrs, clean pipe ends, and mark the insertion depth to ensure correct socket welding.

3. Preheat Fusion Tool:
   Heat the fusion tool plates to the recommended temperature (typically ~260 °C for PPRc — check manufacturer specs).

4. Heat & Join:
   Insert the pipe end and the socket fitting end simultaneously onto the preheated tool faces for the specified heating time.
   Then immediately insert the pipe into the socket and hold straight and steady until the fusion sets.

5. Cooling:
   Allow the joint to cool naturally — do not twist or move while cooling. This ensures a homogeneous, leak-proof joint.

6. System Testing:
   After all joints are complete and cooled, perform a pressure/hydrostatic test to check for leaks and integrity before putting into service.

Important Tips:

• Do not force cool joints with water — cooling must be natural.

• Ensure correct heating times for 50 mm sockets (provided by welding machine/fitting manufacturer).

• Use protective gloves and follow safety guidelines when working with hot tools.

📌 Practical Usage Notes

Advantages of Socket Fusion Joints:

• Permanent, leak-proof connection

• Homogeneous joint — no gaskets, seals, or mechanical parts

• Very low long-term maintenance

System Behavior:

• PPRc systems have smooth internal surfaces, reducing friction and energy losses in flow.

• Material is stable chemically and does not corrode or scale like metals.

🧠 Quick Summary

Socket 50 mm DADEX PPRc PN25 is a high-pressure plastic pipe fitting used to join PPRc pipes in hot & cold water and HVAC systems. It is installed by heat fusion welding, producing durable, leak-proof joints. Thanks to PPRc material and PN25 pressure class, it’s suitable for demanding plumbing and heating/cooling applications where reliability, hygiene, and longevity are essential.
