The Cost-Saving Advantages of Corzan® CPVC to the Construction Trades

The benefits of getting more for your money while keeping a piping project on track should be obvious to any plumbing and mechanical contractor. This is especially true as skilled labor shortages are plaguing the industry. Containing labor costs is more important than ever, so it should be as much a factor as any other in comparing piping materials. That’s why having Corzan® Piping Systems in your construction arsenal is a win-win situation.

It starts with the joining methods. Whether Corzan CPVC is prefabricated or fabricated onsite, installers have considerable flexibility in working with this lightweight material and just a few handheld tools.

Corzan CPVC is so versatile it can be installed by just one or two people using either chemical (solvent welding) or mechanical joining methods, even in small or elevated workspaces. The decision will depend on pipe size and the installation considerations of the particular job.

Although not welding in the usual sense of the word, the solvent welding method involves a safe two-step process and easy cutting, an approach requiring no special tools that offers the lowest overall material cost. When joined correctly with solvent cement, Corzan CPVC pipe segments fuse chemically, with the resultant joint becoming the strongest part of the piping system. 

Mechanical joining involves no cure times at all, which facilitates prefabrication. It is also ideal for alterations or repairs especially in larger facilities, as drying time is eliminated and system shutdown time is dramatically reduced. Depending on the application, installers can either use a cut-groove tool to groove the existing pipe and apply a mechanical coupling to complete the joint, or install a pre-grooved pipe and then apply the mechanical coupling.

But there are other reasons plumbers will spend less time on a job using Corzan CPVC:

  • You’ll never have to guess which ancillary installation products are compatible with the piping thanks to the FBC™ System Compatible Program.
  • Expansion loop requirements for CPVC are not much different than those of copper. Generally, the effects of expansion can be controlled with changes in direction; an offset or expansion loop may be required on a long straight run, usually with just one properly sized expansion loop per single straight run.
  • When system piping is not being driven by a plumbing, mechanical or energy code (e.g., hot and cold water supply lines within conditioned buildings), insulation may not be needed or could be reduced. CPVC will remain condensation-free under most environmental conditions that would cause copper tube to sweat and drip. Water temperature can be calculated versus the dewpoint to determine the best solution.
