What’s the difference between PPR pipe and PPH pipe?

1. Material composition:

PPR tubes are made of a type of polypropylene called random copolymer. This material is designed to provide a variety of properties, including high temperature resistance, good chemical resistance and excellent impact strength.

PPH tubes, on the other hand, are made of polypropylene homopolymer, which is composed of a single type of propylene monomer. PPH has high rigidity, good high temperature resistance and excellent chemical resistance.

2. High temperature resistance:

PPR pipes are known for their excellent heat resistance, making them suitable for use in hot and cold water distribution systems. They can withstand temperatures of up to 70-95°C, depending on the specific grade and manufacturer specifications.

PPH tubes are also high temperature resistant and can withstand temperatures up to 100-110°C, making them suitable for applications involving hot water and certain chemical delivery systems.

3. Chemical resistance:

PPR pipes are resistant to a wide range of chemicals, making them suitable for a wide range of plumbing and heating applications.

PPH pipes are known for their excellent chemical resistance, especially to acids, alkalis and organic solvents, making them ideal for industrial piping systems where chemical resistance is critical.

4. Flexibility and impact strength:

PPR tubes are known for their flexibility and high impact strength, ease of installation and resistance to mechanical stress.

PPH tubes are relatively rigid and have good impact strength, making them ideal for applications where structural integrity and dimensional stability are critical.

5. Application:

PPR pipes are commonly used in plumbing, heating and air conditioning systems in residential and commercial buildings.

PPH pipes are often used in industrial applications, chemical processing plants, and laboratories where resistance to corrosive chemicals and high temperatures is required.
