For example, CPVC solvent cements must meet ASTM F493 specifications, and PVC solvent cements must meet ASTM D2564 specifications. The production process includes the chlorination of PVC via free radical chlorination. Temperatures above those limits will result in softening of the pipe and weak joints, which will lead to leaks and failure. One of the biggest and most … CPVC can handle temperatures up to 200° Fahrenheit, while PVC peaks at 140° Fahrenheit. PVC pipes are white or dark gray in color. Both come in Schedule 40 and Schedule 80 thickness. CPVC and PVC both offer significant chemical resistance and are largely resistant to degradation from acid, alkali, and most inorganic chemicals. The chlorine actually promotes durability and rigidity in higher temperature conditions. CPVC, PEX and PVC pipes and components fail from time to time. Larger PVC pipes are often used in plumbing to distribute non-potable water. PVC vs CPVC Pressure Ratings. CPVC has been installed successfully for nearly 50 years. CPVC is Chlorinated Polyvinyl Chloride. CPVC (chlorinated poly (vinyl chloride) is a strong and rigid thermoplastic material that is used for hot and cold potable water applications in residential construction. As seen in the image below, PVC’s chemical composition is made of two carbon atoms linked together with a perimeter of three hydrogen atoms and one chlorine atom, all attached by single bonds. CPVC stands for chlorinated polyvinyl chloride. 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. PVC pipes are sized by the nominal pipe size (, CVPC pipes are sized by the nominal pipe size (. 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. The color of PVC pipe is traditionally white or dark gray, with a technical description of the pipe printed on the side. Above those temperatures, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing, and therefore, failing of the plumbing system. While the name sounds redundant, it describes the process of increasing the chlorine content in PVC. The primers, solvent cements, and bonding agents are different for PVC and CPVC due to the differences in the material's chemical composition. "I see you offer every kind of PVC or CPVC fitting I need. Per the National Spa and Pool Institute, hot tubs are now designed to heat up to a maximum of 104° Fahrenheit. Commonly used to create plumbing pipes and fittings, polyvinyl chloride is a man-made plastic with added stabilizers that prevent oxidation and degradation. CPVC should only be used when conditions call for it and when higher temperatures are going to be an issue. They are available in the same lengths, with the same end shape options. Washing machine temperatures peak at 140° Fahrenheit. Both CPVC and PP homopolymer are thermoplastics. CPVC Can Tolerate Higher Temperatures than PVC Unlike PVC, whose maximum temperature tops out at 140° F, CPVC piping can withstand temperatures up to 210° F. It is equally effective at lower temperature ranges, as well. CPVC. Often, pipes using the NPS system are light gray, and pipes using CTS system are yellow. Budget-friendly, temperatures under 140° Fahrenheit, most suitable for recreational applications, residential construction, DIY projects and cold water distribution. CPVC vs PVC Pipe Comparison and Differences, The primers, solvent cements, and bonding agents are different for PVC and CPVC due to the differences in the material's chemical composition. PVC has a peak temperature threshold of 140° Fahrenheit. The key difference between UPVC and CPVC is that UPVC is produced without the addition of plasticizers, whereas CPVC is produced by post-chlorination of PVC to enhance the chlorine content in the polymer. It is lightweight and resistant to corrosion and tuberculation. In fact, the first pipeline systems used by the CPVC occurred in 1959, and they continue to work without any problems. CPVC is a PVC homopolymer that has been subjected to a chlorination reaction. However, many hardware stores and home centers carry a different style of pipe called CPVC, also known as Copper Tube Size (CTS) plastic pipe, which is not compatible with FORMUFIT and other brands of PVC fittings. When working with PVC or CPVC, work in a well-ventilated area with proper safety apparel, including gloves, goggles and a respirator if available. Both are safe for use with potable water when ANSI / NSF 61 certified. It is safe to use CPVC in applications where PVC may be used. You must have JavaScript enabled in your browser to utilize the functionality of this website. Main Difference – PVC vs Polycarbonate. If you are going to have any pressure on the pipe then it is best to have nearly straight pipe close to the fitting. Copper has been used in North American plumbing applications for more than 70 years. PVC has a wide range of application in our day to day life. For applications requiring temperatures above that, CPVC (. If a single component made from defective material goes into production, the entire product may be compromised. Both pipe types are available in plain end and bell end. Both PVC and CPVC have been deemed safe for potable water transport, i.e. They are available for engineering and industrial piping projects because CPVC can withstand a greater array of high temperatures.
