Corzan is a trade name for CPVC, where the "C" part of the abbreviation stands for
"chlorinated". The PVC compound is put through a chlorination process which changes some of the properties. One
of the main changes is that the melting temperature of the plastic is higher and so CPVC pipe and fittings can
operate at a higher temperature than standard PVC.
How Do CPVC and PVC Differ?
The main difference that most people are interested in is the temperature range
that CPVC can operate over. PVC has a maximum working temperature of 60 degrees Centigrade, but CPVC can be
taken up to 90 degrees. There are also differences in chemical compatibility - full chemical compatibility
charts are available in our technical section.
Inch and Metric Ranges
Our Corzan CPVC pipe and fittings are available in two ranges. The first is an
imperial range, that is manufactured in the USA by Spears Manufacturing, and the second is metric, which is
European and manufactured by Durapipe. Both systems are manufactured to all the required standards and
