The PPH/PPR pipe production line is a specialized manufacturing system designed to produce PPR (polypropylene random copolymer) pipes and PPH (Polypropylene Homopolymer) pipe.

The primary function of the PPH/PPR pipe production line is responsible for melting, shaping, and cooling the PPH/PPR material to form pipes with consistent dimensions and properties. The line typically includes an extruder, die head, vacuum sizing tank, haul-off machine, cutting unit, and stacker. The extrusion process ensures the uniform distribution of material, resulting in high-quality pipes with excellent resistance to corrosion, abrasion, and chemical exposure.

What’s the difference between PPR pipe and PPH pipe?
1. Material Composition:
PPR pipes are made from a type of polypropylene known as random copolymer. This material is designed to offer a balance of properties, including high-temperature resistance, good chemical resistance, and excellent impact strength.

PPH pipes, on the other hand, are made from polypropylene homopolymer, which consists of a single type of propylene monomer. PPH exhibits high rigidity, good resistance to high temperatures, and excellent chemical resistance.

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

PPH pipes also offer high-temperature resistance and can withstand temperatures up to 100-110°C, making them suitable for applications involving hot water and certain chemical conveyance systems.

3. Chemical Resistance:
PPR pipes exhibit good resistance to a wide range of chemicals, making them suitable for use in various plumbing and heating applications.

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

4. Flexibility and Impact Strength:
PPR pipes are known for their flexibility and high impact strength, which allows for easy installation and resistance to mechanical stresses.

PPH pipes are relatively rigid and offer good impact strength, making them suitable for applications where structural integrity and dimensional stability are important.

5. Applications:

PPR pipes are commonly used in plumbing, heating, and air conditioning systems for both 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.
