Specifying CPVC In Chemical Process Environments  

By Robert Newby and Michelle Knight Noveon, Inc. |

    Since its introduction to the market in 1959, chlorinated polyvinyl chloride (better known as CPVC) has proven suitable for use in a wide variety of chemical process environments. Because it is inert to most mineral acids, bases, salts and aliphatic hydrocarbons, it offers a more reliable, long-term performance than many other materials, including metals and most non-metallic alternatives. In addition to its corrosion resistance, CPVC also offers high impact resistance and heat distortion temperature (HDT), making it suitable even in harsh application conditions. The end result for industrial plants choosing CPVC is longer piping service life, lower maintenance costs and reduced downtime. Despite its proven benefits, CPVC is still not specified as often as it could be. While today it is used more often and in more industries than ever before, its growth in the industrial market has been limited, in part, due to a lack of awareness. More than 47 years after it was invented, CPVC has yet to be mentioned in the engineering curriculum of most universities as educators continue to focus on metals only, in different grades and at various price points.   How CPVC stacks up It is important to keep in mind that no single…
