Check Dimensions Of Flanges 150 LB As Per ANSI B 16.5, Pressure Rating Of Class 150# Flange.


The ASME B16.5 is a standard that provides recommendations for the production and purchase of several kinds of flanges including a blind flange. An ASME B16.5 Class 150 Flange is used to either clean, modify or inspect a piping system. A blind flange is used for any of the above mentioned purposes by terminating the flow of media across the end of a piping system. The blind flange is basically a type of flange that does not have a hub or a bored i.e. a hole in its centre. Class 150 Blind Flanges have the face thickness of a flange, a matching face type, in addition to a similar bolting pattern. Typically blind flanges are recommended to be used to seal a nozzle opening on a pressure vessel.


The ASME B16.5 is a standard that not only covers Flanges but also their Fittings and the pressure-temperature ratings. Apart from Class 150 Pipe Flanges Pressure Ratinge the standard includes the following pressure rating class designations i.e. 300, 400, 600, 900, 1500, and 2500. Other recommendations covered by the specified ASME B16.5 standard include the materials to be used, tolerances, marking, Class 150# Flange Dimension, testing, and methods of designating openings for pipe flanges and flanged fittings.

What Is ASME B16.5 Class 150 Flange?


The Flanges 150 LB As Per ANSI B 16.5 are available between a size range of NPS 1/2 through NPS 24, with their requirements being provided in both metric and U.S units. Limited to flanges and relevant fittings, the Stainless Steel Flanges - ASME / ANSI Class 150 made from forged, cast, or plate materials. Included in the ASME B16.5 standard are requirements and recommendations regarding bolting, gaskets, in addition to flange joints.
