The DN200 PPR electrofusion coupling is designed for large-diameter hot water transmission pipelines. Manufactured using Borouge's RA140E or PPB4228 raw materials, its grey color indicates a pressure rating of 20 bar. The product structure is reinforced for robustness and enhanced reliability, making it suitable for transporting high-temperature fluids through large diameters. It is typically used in small community pipe networks or as the main hot water pipeline in large plants. Furthermore, made from PPR material, it can handle many corrosive fluids, water, or sewage applications, ensuring complete fusion of the thick-walled pipe. It is highly suitable for conveying high-temperature, high-pressure water or steam in large industrial settings.

FAQ

Q: What should I do if the fitting produces noise and vibration during water flow?

A: Open the valve slowly and install an air release valve to reduce the water hammer impact.

Q: Does it matter if there are deep scratches on the fitting's surface?

A: Scratches on non-pressure-bearing surfaces can be monitored during use. Scratches on pressure-bearing surfaces necessitate replacement.

Q: What about aging after more than 10 years of use?

A: Confirm safety through a pressure test, increase the frequency of inspections, and prioritize replacing critical sections.

PPR vs. PE Performance Comparison and Analysis

From a comprehensive performance perspective, PPR and PE fittings each have their strengths.
Advantages of PPR Fittings:
- High-Temperature Resistance: Its core advantage, making it the primary choice for hot water.
- Lower Installation Cost: The investment for a socket fusion machine is relatively lower than for an electrofusion welder.
- Smooth Inner Walls: Results in lower flow resistance.

Disadvantages of PPR Fittings:
- Poor Flexibility: Vulnerable to impact damage and has a higher linear expansion coefficient.
- Poor Low-Temperature Resistance: Can become brittle in low-temperature environments.
- High Dependency on Installation Skill.

Advantages of PE Fittings (especially electrofusion types):
- Excellent Flexibility: Strong resistance to earthquakes and ground settlement.
- Good Low-Temperature Resistance: Stable performance in frigid regions.
- More Reliable Connections: Electrofusion connections offer high consistency in quality.

Disadvantages of PE Fittings:
- Poor High-Temperature Resistance: Cannot be used for hot water systems.
- Higher Equipment Cost: Electrofusion welding machines are expensive.
- Insufficient Rigidity: Aesthetic appearance and support are slightly inferior for exposed installations.
