What is the primary material composition of CPVC pipes?

Chlorinated polyvinyl chloride, or CPVC, is specifically an enhanced version of standard polyvinyl chloride (PVC). The primary distinction lies in the chlorination process that the PVC undergoes, which alters its chemical structure and significantly enhances its capabilities. This modification allows CPVC pipes to handle higher temperatures and pressures compared to regular PVC, making them suitable for hot water applications, such as in residential plumbing systems.

The chlorination also gives CPVC its characteristic resistance to corrosion and degradation, especially in environments where chemicals or heat might otherwise weaken a material that isn't as robust. This makes CPVC an ideal choice for potable water distribution and various industrial applications that require durability under environmental stress.

Understanding the foundation of CPVC being composed of chlorinated polyvinyl chloride is crucial for recognizing why it is often chosen over other piping materials in certain scenarios, such as its compatibility with a wide range of chemicals and its ability to maintain structural integrity under higher temperatures.
