PPR pipe is a straight, rigid cylindrical pipe made from Polypropylene Random Copolymer plastic, manufactured through a continuous extrusion process. These pipes are frequently found in green or white, and are available in outer diameter sizes typically ranging from 20mm to 110mm, resulting in significantly thicker walls compared to PVC pipes.
Key Characteristics of PPR Pipe:
- Material: Polypropylene Random Copolymer (PPR) - a thermoplastic polymer known for its strength, heat resistance, and chemical resistance.
- Shape: Cylindrical and rigid.
- Manufacturing Process: Continuous extrusion.
- Common Colors: Green and white are typical, although other colors may exist.
- Size Range: Outer diameters generally range from 20mm to 110mm.
- Wall Thickness: Noticeably thicker than PVC pipes of similar diameter.
Advantages of Using PPR Pipe:
- Heat Resistance: Can handle high-temperature fluids.
- Chemical Resistance: Resistant to a wide range of chemicals.
- Durability: Long lifespan and resistance to degradation.
- Hygiene: Suitable for potable water systems due to its inert nature.
- Leak-Proof Joints: Joined by heat fusion, creating a homogenous, leak-proof connection.
Common Applications:
- Potable Water Plumbing: Transporting drinking water.
- Heating Systems: Radiator connections, underfloor heating.
- Industrial Fluid Transport: Handling various industrial liquids.
- Air Conditioning Systems: Chilled water applications.
Comparison to PVC Pipe:
| Feature | PPR Pipe | PVC Pipe |
|---|---|---|
| Material | Polypropylene Random Copolymer | Polyvinyl Chloride |
| Heat Resistance | Higher | Lower |
| Jointing Method | Heat fusion | Solvent cement/gluing, threaded fittings |
| Applications | Hot and cold water, industrial fluids | Cold water, drainage, irrigation |
| Wall Thickness | Typically thicker | Typically thinner |
In summary, PPR pipe is a durable and versatile piping solution well-suited for both hot and cold water applications, as well as various industrial fluid transport needs, because of its heat resistance, chemical resistance, and leak-proof jointing capabilities.
