Polypropylene random copolymer (PP-R) pipe is becoming an increasingly popular and cost-effective piping system. PP-R pipes are lightweight, durable and provide a long-lasting, reliable and corrosion-resistant piping solution for various applications. PP-R pipes are engineered to operate reliably at temperatures up to 90°C for pressure pipes and up to 110°C for all other applications.
The temperature resistance of PP-R pipe is determined by the polymer used. In general, the maximum operating temperature of polypropylene varies between 95°C and 135°C, depending on the grades and the amount of comonomer added. PP-R pipes contain a copolymer of propylene and ethylene that gives the pipe an exceptional performance in terms of temperature resistance.
The molecular structure of PP-R pipes has a carbon backbone, which makes them excellent in resisting high temperatures. The carbon backbone is seen in the form of polyethylene, which is a highly crystalline polymer. The high crystallinity of PP-R makes it highly resistant to heat and pressure changes.
The melting point of PP-R pipe is approximately 160°C. This means that, even at high temperatures, the polymer does not break down, deform or create dips or bulges. PP-R pipes have excellent thermal stability, which means they do not expand or contract significantly due to temperature changes.
The combination of these properties ensures that PP-R pipes can reliably function at high temperatures without degradation or failure. As a result, these pipes are ideal for various applications that require high temperature resistance.
PP-R pipes have a wide range of applications, including hot and cold water supply systems, hydronic heating, chemical and industrial applications, and compressed air systems. These pipes exhibit excellent chemical resistance and are not affected by most chemicals.
PP-R pipe systems are highly resistant to corrosion and do not require expensive corrosion protection coatings. This is because the polymer material is inherently corrosion-resistant and the smooth inner-bore of the pipe discourages scale and dirt buildup.
PP-R pipes are also resistant to microbiological growth, which means they are hygienic and safe for potable water distribution systems. These pipes are easy to install and require minimal maintenance. The installation process involves welding or fusion, which creates a seamless connection and eliminates leak-prone joints.
In summary, the withstand temperature of the PP-R pipe is up to 90°C for pressure pipes and 110°C for other applications. PP-R pipes are lightweight, durable and provide a long-lasting, reliable and corrosion-resistant piping solution for various applications. These pipes exhibit excellent chemical resistance and are highly resistant to corrosion, microbiological growth, and most chemicals. PP-R pipe systems are hygienic, easy to install and maintain, and require minimal maintenance.
PP-R pipes are a cost-effective piping solution that offers significant benefits over traditional metal piping systems. PP-R pipes are an excellent investment for any application that requires reliable and long-lasting piping solutions. In addition to performing reliably at high temperatures, they offer a range of benefits that make them an ideal choice for various applications.
