PP RCT Pipe

PP-RCT Pipe has higher pressure resistance and long-term thermal stability, suitable for high-temperature water transportation systems

In the modern construction and infrastructure industry, the demand for durable, safe, and high-performance piping systems is ever-increasing. Among various types of plastic pipes, PP-RCT pipe has emerged as a revolutionary product due to its excellent mechanical properties, pressure resistance, and long-term thermal stability. These characteristics make it particularly suitable for high-temperature water transportation systems such as hot water supply, radiant heating, and industrial applications.

Shanghai Zhongsu Pipe Co., Ltd., established in 2004 with a registered capital of RMB 1.01 billion, is a leading manufacturer specializing in high-quality plastic piping systems including PP-R, antibacterial PP-R, anti-UV PP-R, PP-RCT, and HDPE pipes and fittings. Located in Jinshan District, Shanghai, China, ZHSU occupies an area of 70,000 square meters and has built itself into a first-class enterprise in the industry through continuous innovation, strict quality control, and customer-centric service.

The Technical Advantages of PP-RCT Pipes
PP-RCT technology represents a significant advancement over traditional PP-R (Polypropylene Random) pipes. The key difference lies in the molecular structure and crystallinity of the material. PP-RCT is produced using a special polymerization process that enhances the transition temperature of the material, resulting in superior pressure resistance even at elevated temperatures.

Standard PP-R pipes are typically rated for a maximum operating temperature of 70°C under standard conditions. However, PP-RCT pipes can maintain their structural integrity and pressure-bearing capacity at temperatures up to 95°C over extended periods. This makes them ideal for use in central heating systems, district heating networks, and other applications where long-term exposure to high-temperature water is inevitable.

Moreover, PP-RCT pipes exhibit excellent creep resistance, meaning they do not deform or fail under constant stress over time. This ensures the safety and reliability of the entire piping system, especially in environments where the pipes may be subjected to both high pressure and high temperature simultaneously.

Applications of PP-RCT Pipes in Real Projects
The unique properties of PP-RCT pipes have led to their widespread adoption in various sectors:

Building Water Supply Systems : In residential and commercial buildings, PP-RCT pipes are used for both cold and hot water distribution. Their ability to withstand high temperatures and pressures without degradation ensures a long service life and minimal maintenance.
Radiant Floor Heating Systems : Due to their flexibility and heat resistance, PP-RCT pipes are commonly used in underfloor heating systems. They provide efficient and uniform heat distribution while maintaining structural integrity under continuous operation.
Industrial Process Piping : Many industries require the transport of hot liquids or steam. PP-RCT pipes offer a lightweight yet robust alternative to metal piping, reducing installation costs and improving energy efficiency.
Municipal Infrastructure : ZHSU’s PP-RCT pipes are increasingly being used in municipal water supply projects, particularly in regions with extreme climate conditions. Their durability and resistance to environmental stress cracking make them ideal for underground installations.
Rural Drinking Water Projects : As part of national initiatives to improve rural water access, ZHSU has developed large-diameter PE pipes up to DN1200mm, complementing its PP-RCT product line. These solutions help deliver clean water safely and efficiently to remote areas.
