ANSI B16 47 Flange B16.47 Series B Manufacturer In India, Check MSS SP-44 A182 F316L B16.47 Series B Class 150 Flange Dimension In MM.


The ASME B16.47 is a standard which covers pressure-temperature ratings, materials, ANSI B16 47 Flange B16.47 Series B Dimensions, tolerances, marking, along with testing for flanges in a piping system. Generally, the ASME B16.47 is produced in size ranging between NPS 26 through NPS 60, in the following pressure rating Classes 75, 150, 300, 400, 600, and 900. An ASME B16.47 Series B Flange could be produced from materials such as either cast, forged, or plate. Although plates are used to manufacture blind flanges only. Requirements and recommendations with regards to both bolting and gaskets are also included in the ASME B16.47 standard.

What Is ASME B16.47 Series B Flange?


In comparison to Series A flange, the ANSI 16.47 Series B Slip On Flange tend to be thinner, lighter and weaker. They also can often handle a lesser external load or stress than Series A. This is why Series A flanges tend to be much more expensive in comparison to a B16.47 Series B Class 150 Flange. Although the flange produced under ASME B16.47 Series B would require smaller fasteners, such as bolts & nuts, the quantity is larger in comparison to series A. Moreover, Series B flange also usually have a smaller bolt circle diameter as opposed to Series A flanges. Generally, there is less flanges movement after the installation of flanges due to a smaller bolt circle diameter. Although both standard ASME B16.47 Series A and B define weld neck flanges as well as B16.47 Series B Blind Flange in raised face type, Series B does not define ring type joint (RTJ) flanges between pressure rating i.e. Class 300 through Class 900 within this standard. Many buyers choose to use an ANSI B16.47 Series B Reducing Flange for the purpose of either refurbishment or replacement jobs.
