What type of pipe is rated 180°F at 100 psi and is typically used in hot water distribution systems?

Chlorinated polyvinyl chloride (CPVC) is specifically designed to handle higher temperatures compared to regular PVC, making it suitable for applications like hot water distribution systems. It is rated for continuous operation at temperatures up to 180°F at pressures up to 100 psi, which is essential when dealing with hot water in residential and commercial plumbing.

The chemical structure of CPVC allows it to withstand high temperatures and pressures, ensuring durability and reliability in hot water applications.

In contrast, other materials such as regular PVC are not suitable for hot water because they can deform or weaken under higher temperatures, leading to potential failures in the plumbing system. Polybutylene (PB) and polyethylene (PE) also lack the same thermal resistance required for hot water applications, limiting their use in such scenarios. Therefore, the characteristics of CPVC make it the ideal choice for the described application.
