Properties of CPVC Pipes
In this section, we will discuss the properties of CPVC pipes and how they differ from PVC pipes. CPVC pipes share many similarities with PVC pipes, such as corrosion resistance and a smooth surface. However, CPVC pipes have distinct advantages that make them suitable for specific applications.
One of the key properties of CPVC pipes is their ability to withstand higher temperatures compared to PVC pipes. CPVC can handle temperatures up to 200°F, making it ideal for hot water applications. This increased temperature tolerance allows CPVC pipes to maintain their structural integrity and strength, even when exposed to high heat. In contrast, PVC pipes are more suitable for cold water systems.
CPVC pipes have a higher tensile strength compared to PVC pipes. With a rating of 8200 PSI, CPVC pipes offer superior durability and resistance to external forces. This makes them a reliable choice for applications that involve high-pressure water systems or areas with heavy loads. PVC pipes, although strong, have a lower tensile strength compared to CPVC pipes.
Color and Sizing
CPVC pipes are available in different colors, including off-white, light gray, or yellow. The color may vary depending on the sizing system used, whether it’s copper tube sizes (CTS) or nominal pipe sizes (NPS). This color distinction helps in easy identification and differentiation of CPVC pipes from other plumbing materials.
CPVC pipes are widely used in both hot and cold potable water systems. Their temperature resistance and high-tensile strength make them suitable for residential, commercial, and industrial applications. CPVC pipes also find uses in chemical processing, industrial plumbing, and fire suppression systems, thanks to their ability to withstand a wide range of chemicals and substances.
Now, let’s take a look at a table that summarizes the properties of CPVC pipes for a quick reference:
|Up to 200°F
|Off-white, light gray, or yellow
