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 plumbing and heating installations due to their excellent resistance to chemicals and high temperatures. Since the 2000s, they have also been widely used in North America. As a further development, PP-RCT pipes were developed to offer improved performance properties such as higher long-term strength at elevated temperatures.

PP-RCT pipes and fittings: International standards and certifications

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

Various wall thicknesses and sizes

PP-RCT pipes are available in a variety of wall thicknesses, which are characterized the Standard Dimension Ratio (SDR). This enables adaptation to different pressure requirements and areas of application. Sizes range from small diameters for domestic installations to large diameters for industrial applications such as chemical processing and cooling systems.

Connection and welding

PP-RCT pipes are joined heat fusion, a reliable method in which the pipe ends are heated and then joined together to create a solid connection. This method ensures a leak-free installation and a long service life of the piping systems.

Advantages of 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.
  • Cost-effectiveness: Reduced product and installation costs compared to metal pipes. Lower maintenance costs and longer service life lead to savings over the entire service life of the system.
  • Easy installation: Lightweight pipes that are easy to handle and install, saving time and labor.
  • Environmentally friendly: PP-RCT pipes are recyclable and have a low environmental impact, resulting in a sustainable solution for your projects.

Application of PP-RCT pipes

  • Sanitary installations: In residential, commercial and industrial buildings for the distribution of drinking water and waste water.
  • Heating and cooling systems: For the distribution of hot and cold water as well as 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-RCT pipes are resistant to aggressive soil conditions.
  • Geothermal heating and cooling systems: PP-RCT pipes are ideal for use in geothermal systems to make efficient use of geothermal energy.
  • Hot and cold water supply systems: PP-RCT pipes are widely and equally used for hot and cold water supply systems in residential, commercial and industrial buildings. They are highly temperature and pressure resistant and can distribute heat evenly, making them ideal for transporting water in such systems. They are also used in heating systems such as underfloor heating, etc.
  • Transportation of chemicals and liquids: As PP-RCT pipes are known to be corrosion resistant, they are ideal for the transportation of chemicals and liquids in industrial processes.
  • Infrastructure: PP-RCT pipes are also used in infrastructure projects such as sewage systems, drainage systems and cable ducts. Due to their corrosion and abrasion resistance, these pipes are ideal for such applications.
