What is the decomposition point range of PVC pipe?

The decomposition point range for PVC (Polyvinyl Chloride) pipe occurs between 401 to 411 degrees Fahrenheit. At this temperature range, PVC begins to break down chemically, resulting in the release of harmful gases such as hydrogen chloride. This is an important factor to consider in plumbing applications to avoid situations where high temperatures could lead to material failure or health hazards.

Understanding the decomposition point is crucial for a plumbing contractor because it determines the maximum temperature that PVC can safely handle without undergoing degradation. This knowledge helps in making informed decisions about the use of PVC in various plumbing applications, particularly in environments where exposure to heat is a potential risk.
