WebAug 28, 2024 · “ANSI class” is the designation for pressure-temperature ratings of pipe flanges. In its denotation, the word Class is followed a by dimensionless number. This includes Class 150, 300, 400, 600, 900, 1500, and 2500. Unsurprisingly, the phrase ANSI class, does, in fact, derive from the American National Standards Institute. WebFlanges can withstand different pressures at different temperatures. As temperature increases, the pressure rating of the flange decreases. For example, a Class 150 …

WebThere are seven different pressure ratings for flanges- 150, 300, 400, 600, 900, 1500, and 2500. The ASME B16.5 Class 1500 Flange comes with the correct dimensions of NPS ½ to NPS 24 to be a pipe flange or a flange fitting. The ANSI B16.5 Class 1500 RTJ Flanges have a bolt circle diameter, which is about 1/8th times bigger than the bolt's ... WebThe pressure ratings change based on the material from which it is made and/or the temperature at which it operates. The nominal flange Class (e.g., Class 125) generally represents the maximum working pressure at the temperature of saturated steam at that pressure. For example, an ANSI/ASME B16.1 Class 125 flange is rated for 125 PSI at … WebPressure-temperature Ratings The pressure-temperature ratings of all Westlake Pipe & Fittings PVC and CPVC flanges are listed as 150 psig at 73° F. Flanges and flange fittings covered by the ANSI b16.5 shall be designated as one of the following: Class 150, 300, 400, 600, 900, 1500, or 2500. biological classification of human
