What is CPVC piping?
Chlorinated polyvinyl chloride (otherwise known as CPVC) is created by chlorinating polyvinyl chloride (PVC) resin, which has the ability to withstand greater heat and provides much greater flexibility than regular PVC. It's typically used in fire sprinkler systems and many other applications that involve transporting both hot and cold liquids, potable or otherwise.
Why are CPVC systems so popular?
In addition to the previously mentioned flexibility and ability to withstand high temperatures, this piping is extremely long-lasting, lightweight, easy to transport, easy to install and has practically no scrap value. This latter point means it's much less prone to job site theft than other materials such as copper or carbon steel.
What makes them so effective?
CPVC pipes are incredibly resistant to corrosion, tuberculation and deposit build-up over time. Unlike some metal piping, the plastic is good to last several hundred years without any signs of decay, which is why it's not uncommon for older cities in the world to dig up roads and replace rusted metal water lines with CPVC alternatives.
When was CPVC piping invented?
The first CPVC piping was created by a manufacturer based in Michigan, USA during the 1960s. A couple of decades later and it had received the important certifications necessary from the United Kingdom, United States and Canada allowing it to be used in the fire safety industry. Now CPVC piping is a mainstay in fire sprinkler systems all over the developed world
