Please note: The following overview is based on Universal Plumbing Code UPC guidelines - local plumbing codes can supercede this, so be sure to check with your local authorities before embarking on anything.
Due to the increased shipping cost for any kind of rigid pipe longer than four feet, we are unable to sell it at a cost that is affordable for our customers. We recommend you purchase this type of pipe at your local hardware or home improvement store. However, we do offer rigid copper less than four feet, as well as great deals on flexible PVC, copper tubing, PEX, and other vinyl tubing since these can be rolled and are much easier to ship, keeping your cost lower.
You'll be able to greatly reduce the number of fittings used for most applications. Once you have used this flexible pipe, you'll wonder why everyone doesn't use this product. If you are going to have any pressure on the pipe then it is best to have nearly straight pipe close to the fitting.
Plumbing Terms. View Cart. Home use tends to be mostly in HVAC applications, such as plumbing or ventilation. PVC pipe is able to handle temperatures up to degrees Fahrenheit before softening, whereas CPVC pipes may handle temperatures up to degrees. The overflow pipe that connects to the pressure relief valve is a commonly made of CPVC.
As the name implies, CTS scaled CPVC is a perfect replacement for copper piping and will fit into the same confines as your existing copper pipe. A third consideration is chemical exposure.
Always consult a chemical compatibility chart before choosing between these two materials when using in a chemical application. In addition, combining the two may compromise your system. These two materials have different pressure and temperature ratings which could lead to leaks or other issues during use. CPVC is not only available in a number of pipes, but also a wide range of fittings. These fittings will allow you to connect CPVC pipes in a wide range of configurations.
Reducing joints allow you to connect a different pipe size, but are not available in all types of fitting. Most reduction fittings are available with either CPVC or brass threads. Some of the more common fittings include:. No spam, we promise. The Tg is the point where the polymer transitions from a hard, glassy material to a soft, rubbery substance, losing its structural integrity. Thermoplastics, such as polypropylene and polyethylene, often give all thermoplastics a negative reputation when it comes to fire performance.
However, susceptibility to burning and melting is not true of all thermoplastics. Industrial CPVC, specifically, is engineered to limit flammability and smoke production. Specifically, there are ASTM tests that measure a material's:. Flash Ignition Temperature : The lowest temperature at which sufficient combustible gas can be ignited by a small external flame. The resin is then shaped or molded into the products used for residential, commercial and industrial use. The ease of installation and corrosion resistance makes it a valuable replacement to alternative materials.
CPVC is commonly specified as pipe, fittings and valves where heat, pressure and chemical resistance are concerns. Ducting: With increasing air emission regulations, the need for reliable fume handling systems, especially in corrosive environments, is growing rapidly. And, when the sheet or liner will face less temperature and pressure demands, PVC can be specified.
Other product types: Often starting with CPVC or PVC sheet as a base, fabricators can cut and form the material for use in a number of varying applications. Keeping those advantages in mind, common uses for each differ depending on the demands of the application. PVC is a low cost, reliable material that can also be installed without the use of skilled, expensive welders.
