Green PPR Pipes And Fittings 2

PPR fittings – also known as Polypropylene Random Copolymer fittings – have become increasingly popular in recent years due to their corrosion resistance, heat resistance, and relatively low cost. As a result, they have had a significant impact on plumbing codes and standards.


One of the main benefits of PPR fittings is their ability to withstand high temperatures and pressure. They are commonly used in hot and cold water systems, as well as in heating systems. This has led to the development of new standards and codes to govern their installation and use.


In many countries, including the United States, PPR fittings are covered under the International Plumbing Code (IPC). The IPC sets out the minimum standards for plumbing installations, including those for PPR fittings. These standards cover factors such as the required thickness of PPR pipes, the type of adhesive used to connect them, and the amount of pressure they can withstand.

In addition to the IPC, there are also several other codes and standards that govern the use of PPR fittings. For example, in Europe, PPR fittings are typically governed by the ISO 15874 standard. This standard sets out requirements for dimensions, performance, and testing of PPR pipes and fittings.
Despite their many benefits, it is important to note that PPR fittings are not without their limitations. For example, PPR pipes may not be suitable for use with certain chemicals or in areas with high levels of UV radiation. Additionally, they may not be suitable for use in large commercial or industrial settings where greater durability may be required.


In summary, the use of PPR fittings has had a significant impact on plumbing codes and standards. As more and more buildings are built with PPR systems, it is likely that codes and standards will continue to evolve to reflect the unique properties and requirements of these materials. As with any plumbing system, it is important to ensure that PPR fittings are installed correctly and in accordance with applicable codes and standards to ensure their safety and effectiveness.
