A Brief Description of Chlorinated Polyvinylchloride (CPVC)

January 09, 2017

Chlorinated Polyvinylchloride (CPVC)Chlorinated Polyvinylchloride (CPVC) is a thermoplastic compound produced by chlorinating polyvinyl chloride Polyvinyl Chloride (PVC) resin that is considerably more pliable and has the ability to resist high amount of temperatures as compared to the standard PVC. It is used in the making of cold and hot water pipes, along with industrial liquid handling. PVC is chlorinated with the help of free radical chlorination method, in which the amount of chlorine alters depending on the manufacturer. Moreover, this compound is a great corrosive-resistant. It possesses good resistance to heat, i.e., approximately up to 90oC; also it exposes superior resistance to alkalis and acids. Furthermore, CPVC exhibits tremendous thermo-mechanicals and can be cut, manufactured, machined and welded. A report on Chlorinated Polyvinylchloride (CPVC) market mentions that this market is segmented as solid-phase method, solvent method, and aqueous suspension method.

Chlorinated Polyvinylchloride has several applications out of which a few are listed below:

  • Industrial liquid handling applications
  • Construction
  • Plumbing – cold and hot water pipe
  • Fire suppression systems

Also, apart from these CPVC piping systems are the most preferred due to the following reasons:

  • Cost efficient
  • Broadly accepted by codes
  • Environment friendly
  • User-friendly installation
  • Render long service life
  • Corrosion resistant

Benefits of using CPVC based pipes:

Great resistance to chemicals, abrasion and corrosion – this compound does break or wither even under roughest water conditions and extreme conditions such as coastal salt air exposure, reduced pH water, and corrosive soils. Besides, this compound can be directly buried beneath concrete slabs without any kind of chemical interaction with concrete.

Cost efficient, aesthetical, and user-friendly installation and handling – since CPVC based pipes are not heavy, their shipping costs are not much. Also, with safe and easy handling, the overall labor cost is considerably low. The installation is done by rapid cold welding which automatically makes it cost efficient since it requires no heat or electric source.

Most preferred and suited for carrying drinking water – hinders any kind of bacterial growth and hence keeps the quality of water healthy and consumable. There are well-suited even for higher pH levels of less than 6.5, although Chlorinated Polyvinylchloride used for this particular purpose must have NSF certification according to ANSI/NSF Standard 61/ program policy 45.
