Flange Rating Chart

Flange Rating Chart - The higher numbers indicate greater pressure and temperature resistance. Web flange tables temperature/pressure ratings for steel flanges. Web pressure (psig) and temperature ratings for steel pipe flanges and flanged fittings Web here is a brief explanation: In other words, when the pressure goes down, the temperature goes up and vice versa. Asme b16.5 standard covers steel pipe flanges and flanged fittings from nps 1/2 through nps 24 metric/inch in pressure class 150 to class 2500. With so much at stake, it’s vital that flanges in the oil, gas, and petrochemical industries can withstand the temperatures and pressures they’re subjected to. Web the following ansi flange charts & flange tables provide flange dimensions including, flange overall diameters, number of bolts and bolt size for the most common sizes of ansi flanges for ratings from ansi 150 through to ansi 1500. Each class has a specific pressure and temperature range. 1 psi (lb/in2) = 6,894.8 pa (n/m2) popular internal searches in the engineering toolbox.

This Article Discusses Flange Ratings And.

From the chart below you can easily find out if your system requirement matches with flange class or not. Web the following ansi flange charts & flange tables provide flange dimensions including, flange overall diameters, number of bolts and bolt size for the most common sizes of ansi flanges for ratings from ansi 150 through to ansi 1500. Web asme/ansi b16.5 standard provides seven flange pressure ratings: 150, 300, 400, 600, 900, 1500, and 2500.

The Tables You Will Find Below Are Organized As Per The Pressure Classes That You Can Find At The Top.

Web flange tables temperature/pressure ratings for steel flanges. Web flange ratings are typically designated by a numerical value, such as class 150, class 300, and class 600; With so much at stake, it’s vital that flanges in the oil, gas, and petrochemical industries can withstand the temperatures and pressures they’re subjected to. Asme b16.5 standard covers steel pipe flanges and flanged fittings from nps 1/2 through nps 24 metric/inch in pressure class 150 to class 2500.

Web Pressure (Psig) And Temperature Ratings For Steel Pipe Flanges And Flanged Fittings.

Web for example, a class 150 flange is rated to approximately 270 psig at ambient conditions, 180 psig at approximately 400°f, 150 psig at approximately 600°f, and 75 psig at approximately 800°f.
