ASME 31.3 Allowable Pressure Calculator

The allowable pressure in a 4 inch schedule 40 carbon steel pipe with outside diameter 4.5 in, wall thickness 0.237 in and allowable stress 16000 psi, can with quality factor E for steel 0.8 and wall thickness coefficient 0.4 be calculated as p = 2 (0.237 in) (16000 psi) (0.8) / ((4.5 in) - Flange Ratings and Flange Classes for ASME FlangesFor example, when we say class 150 flange, it means that safe working pressure for this flange at rated temperature for a given material is 150 pounds per square inch. See below the some of the common way to refer the 150 Class flange. Class #150 flange; 150-pound flange; class 150 flange pressure rating; 150 pressure rating flange; 150 lb flange

The more tension there is on a flange, the more likely it is to fail. Source:Werner Sölken. To prevent failure from heat and pressure, a parts pressure rating needs to be taken into account. Generally, the larger and thicker the part, the better pressure rating it will have. Pressure and Temperature Rating of ASME Flanges
    • Pressure Rating DesignationList of Material Specifications Table-1APressure Temperature Ratings TableEstablishing The Pressure-Temperature RatingsAppendix A of ASME B16.5 provides the procedures on how the pressure-ratings for ASME B16.5 are derived. The pressure-temperature ratings for only class 300 and higher flanges are established by the following equation:Pt = (C1S1Pr/8750) Pr = 8750*[Pt/(C1S1)] where C1 = 10 when S1 is eed in MPa units and the resultant Pt will be in bar units (C1 = 1 when S1 is eed in psi units and the resultant Ptwill be in psi units) Pr= pressure rating class index. For all designations Class 300 and abovANSI B16.5 - Steel Pipe Flanges - Pressure and Temperature Pressure (psig) and temperature ratings for steel pipe flanges and flanged fittings according the American National Standard ANSI B16.5 - 1988 Group 1.2:For full table - rotate the screen!

      May 16, 2013 · Use the p,T-rating of the CS [or 316 - whatever suits the service] backing ring (actually LJ flange), and do the pipe wall thickness calc for the B16.9 Ti stub end to e.g. B31.3 (assuming thats your design code). Make sure you select the proper stub end to Pressure/Temperature ratings of PN64 flanges - Pipelines May 21, 2002 · I need to determine the ratings for PN64 flanges in 316L stainless.
