temperature and pressure ratings of pvc
rating in all sizes, Schedule 40s maximum pressure rating (figured at 72.4°F) varies with each size (see Pipe Selection Chart on A-36). Pressure ratings for transmitting warmer or cooler liquids can be determined using the Conversion Chart shown on page A-36. The maximum recommended temperature for Schedule 40 PVC is 130°F. CPVC Fitting & Pipe Specifications - Large Diameter PVC Corrosion resistant pressure pipe, IPS sizes 1/4" through 24", for use at temperatures up to and including 200°F. Pressure rating (130 psi to 1130 psi) varies with schedule, pipe size, and temperature. Generally resistant to most acids, bases, salts, aliphatic solutions, oxidants, and halogens.
When compared to generic CPVC materials, fittings made from Corzan CPVC demonstrated improved creep resistance, and the ability to better withstand long-term, high-temperature hydrostatic pressure. These fittings lasted four times longer than those molded with other CPVC compounds when pressure tested at 180°F (82.2°C) at 551 psi. Flange Pressure Rating Explained (and Charts Sep 20, 2017 · Select a rating based on the maximum pressure you expect at that temperature level (i.e. select one column in that line) Voilà, you have the required rating! To help you do this easily, find below the ASME B16.34 pressure rating charts for the PRESSURE RATINGS FOR PIPE AND FITTINGSpressure rating obtained from the upper table by the correction factor from the upper table in the next column. Below 73°F the pressure rating will be the same as the base pressure in the table above. PLASTIC PIPING IS NOT RECOMMENDED FOR COMPRESSED AIR OR GAS SERVICE.

9 rows · Vicat Softening Temperature. - is the temperature where a needle shaped penetrator sinks into a Pressure Temperature Rating - Piping StudyThe most common way of specifying pipe pressure temperature rating is given by ASME 16.5, using pound ratings (or lb ratings) #150, #300, #400, #600, #900, #1500 and #2500. The pressure rating or pound rating for a pipe is determined using the design pressure and design temperature for the pipe. Schedule 80 CPVC Pipe Dimensions & Pressure RatingsDimensions & Pressure Ratings Maximum CPVC Service Temperature 200°F Pressure De-rating at Elevated Temperatures The pressure ratings above are for water at 73 degrees Fahrenheit. To calculate elevated temperature rating use the following formula:Schedule 80 CPVC Pipe EX:2" CPVC SCHEDULE 80 @ 120°F = 400 psi x 0.65 = 260 psi max. @ 120°F
Pressure De-rating at Elevated Temperatures The pressure ratings above are for water at 73 degrees Fahrenheit. To calculate elevated temperature rating use the following formula:Max Pressure = (73) x (Derating Factor) Schedule 80 Pipe PVC Pipe Operating Temp (°F) De-Rating Factor 73 1.00 80 0.88 90 0.75 100 0.62 110 0.51 120 0.40 130 0.31 140 Schedule 80 PVC Technical Information Schedule 80 PVC Schedule 80 PVC Pipe Dimensions & Pressure Ratings Made in the U.S.A.
