"ANSI Class" Ratings of Pipe Flanges - ANSI Blog

Aug 28, 2018 · 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.ANSI B16.5 - Maximum Pressure and Temperature Ratings of ansi class ratings of pipe flangesThe Maximum allowable non-shock pressure (psig) and temperature ratings for steel pipe flanges and flanged fittings according the American National Standard ANSI B16.5 are given in the table below. Flanges and their Fittings are a common feature in the process plants.

AWWA Vs. ANSI Flange Standards, AWWA pipe flanges

ANSI covers numbered class flanges from 150 to 2500, and AWWA standards encompass lettered flange classes B, E, F, and the commonly used class D connection.

ASME ANSI B16.5 standard provides seven flange pressure ratings 150, 300, 400, 600, 900, 1500, and 2500. They are also known as Flange Class and denoted by Class, followed by anyone of the above-mentioned dimensionless numbers. They are also referred to as Pound Rating or Pressure Class Rating.

The Difference in ANSI Class Ratings for Y Strainer Flanges

ANSI ratings are a set of standards created by the American National Standards Institute to designate the pressure-temperature ratings of pipe flanges. Traditionally, valves that have flanges connected are described with ANSI Class ratings.The Difference in ANSI Class Ratings for Y Strainer FlangesThe ANSI Class rating of a flange is defined as the maximum amount of pressure that the flange can withstand at increasing temperatures. There are seven primary pressure classes for flanges. They are 150, 300, 400, 600, 900, 1500, and 2500. You may see the terms class, pressure rating, lbs., or #, referring to the rating of flanges.
