What are PP-R pipes?

The History of PP-RCT Pipes

The development of polypropylene (PP) pipes began in the 1970s in Europe for industrial applications, particularly in the chemical and food industries. In the 1980s, PP pipes found their way into sanitary and heating installations due to their excellent resistance to chemicals and high temperatures. Since the 2000s, they have also become widely used in North America. As a further development, PP-RCT pipes were developed to offer improved performance characteristics such as higher long-term strength at elevated temperatures.

International Standards and Certifications

PP-R and PP-RCT pipes comply with strict international standards and certifications, including ASTM (American Society for Testing and Materials), DIN (Deutsches Institut für Normung), ISO (International Organization for Standardization), and NSF (National Sanitation Foundation). These standards ensure the highest quality and safety for use in sanitary and heating applications.

Various Thicknesses and Sizes

PP-R and PP-RCT pipes are available in a variety of thicknesses characterized by the Standard Dimension Ratio (SDR). This allows adaptation to various pressure requirements and applications. Sizes range from small diameters for household installations to large diameters for industrial applications such as chemical processing and cooling systems.

Connection and Welding

The connection of PP-R and PP-RCT pipes is done through heat fusion, a reliable method where the pipe ends are heated and then joined together to create a solid connection. This method ensures leak-free installation and long-lasting piping systems.

Advantages of PP-R and PP-RCT Pipes

• Drinking Water Safety: Certified to NSF/ANSI/CAN 61 for safe use with drinking water.
• Durability and Reliability: High resistance to corrosion, deposits, and chemical influences for a long service life.
• Economy: Reduced product and installation costs compared to metallic pipes. Lower maintenance costs and longer service life lead to savings over the entire life of the system.
• Easy Installation: Lightweight pipes that are easy to handle and install, saving time and labor.
• Environmental Friendliness: PP-R and PP-RCT pipes are recyclable and have low environmental impact, making them a sustainable solution for your projects.

Applications of PP-R and PP-RCT Pipes

The application areas of PP-R and PP-RCT pipes are extremely diverse and include:

• Sanitary Installations: In residential, commercial, and industrial buildings for the distribution of drinking water and wastewater.
• Heating and Cooling Systems: For the distribution of hot and cold water as well as for underfloor heating, air conditioning, and cooling systems.
• Industrial Applications: In the chemical industry, food processing, agriculture, and many other areas where chemical resistance and high temperatures are required.
• Agricultural Irrigation Systems: For the irrigation of fields and plantations, as PP-R and PP-RCT pipes are resistant to aggressive soil conditions.
• Geothermal Heating and Cooling Systems: PP-RCT pipes are ideal for use in geothermal systems to efficiently harness geothermal energy.
• Hot and Cold Water Supply Systems: PP-R pipes are commonly used for hot and cold water supply systems in residential, commercial, and industrial buildings. They are highly temperature and pressure resistant and can evenly distribute heat, making them ideal for water transport in such systems. They are also used in heating systems such as underfloor heating, etc.
• Transport of Chemicals and Liquids: Since PP-R pipes are known for their corrosion resistance, they are excellent for transporting chemicals and liquids in industrial processes.
• Infrastructure: PP-R pipes are also used in infrastructure projects such as wastewater systems, drainage systems, and cable ducts. Due to their corrosion and abrasion resistance, these pipes are ideal for such applications.
