The Coveted PPH Pipe Fittings


Polypropylene (PP) Pipe comes in two basic types: homopolymer (PPH) and copolymer (PPC). Although similar in many aspects, each type exhibits significant differences in appearance and performance. This time, we’ll delve into the introduction of polypropylene material, specifically PPH.

What is PPH?

Polypropylene is one of the most widely used chemical materials. It boasts stronger rigidity compared to polyethylene, especially in high-temperature ranges (up to +100°C). Additionally, it offers excellent chemical resistance, maintaining good performance when exposed to various substances over extended periods, along with high stress cracking resistance.

Differences Between PP and PPH Pipes Special materials for PP pipes are divided into three generations: the first generation is homopolymer polypropylene modified, known as PP-H; the second generation is produced by the copolymerization of PP and PE segments, called PP-B; the third generation is randomly polymerized, modified from copolymer polypropylene (PP-R). These three materials differ in processing performance and resistance to environmental stress cracking. PP-B: Poor strength but good impact resistance. It exhibits some toughness when subjected to impact but relatively low strength. PP-H: Good strength but poor impact resistance. While it has high strength, it tends to be more brittle when subjected to impact. PP-R: Overcomes the shortcomings of PP-B and PP-H. It is modified from copolymer polypropylene and exhibits good processing performance and resistance to environmental stress cracking. After 50 years of production, PP-R pipes still maintain high strength and demonstrate better durability compared to PP-B and PP-H.

Advantages of PPH Pipe Fittings

Longevity: CPVC pipes can be safely used for over 50 years at rated temperatures and pressures. This indicates excellent durability, eliminating the need for frequent replacement or maintenance.

Superior Corrosion Resistance: CPVC pipes withstand corrosion from high-concentration acids and alkalis within the pH range of 1-14. This makes them suitable for use in various chemical environments, whether in industrial applications or household use.

Thermal Energy Efficiency: CPVC pipes have a low thermal conductivity, performing well in hot water transmission and heating systems. They help reduce heat loss, provide better insulation, and thus save energy consumption.

Reliable Connection Performance: The interface strength of CPVC pipes after thermal fusion exceeds the strength of the pipe body, ensuring strong and reliable connections. This means that even under land movement or heavy loads, the joints will not break, ensuring the integrity of the pipeline system.

Ease of Construction: CPVC pipes have a lighter weight, making handling and installation easier. Its welding process is relatively simple and can be constructed with basic tools and techniques. This not only reduces construction time but also lowers overall project costs.


PP pipes and PPH pipes are both polypropylene pipes, but they have slight differences in processing performance, strength, impact resistance, etc. In comparison, PPH pipe fittings exhibit excellent corrosion resistance, thermal energy efficiency, reliable connection performance, and ease of construction, making them highly suitable for use in various chemical environments. They also offer long service life and lower maintenance costs. Therefore, when selecting pipe materials, the choice should be based on specific usage requirements and environmental conditions.
