ASME B16 47 flange is  just another name for ANSI B16.47 type of flange. Therefore, there is hardly or no difference between both, ASME and ANSI.  The full form of ASME stands for American Society of Mechanical Engineers, while the full form of ANSI stands for the American National Standards Institute. Although both these organizations are non-profit ones, they are private organizations. Both the ASME and ANSI focus principally on bringing about uniformity in numerous kinds of voluntary standards which are used in diverse fields of engineering.

The ansi b16.47 flanges fall under the group of large diameter steel pipe flanges. The size range of the ansi b16.47 flange dimensions ranges between NPS 26 to NPS 60. These flanges can further be divided into two  classes i.e. - Series A ANSI B16.47 flanges  and ANSI B16.47 Series B flanges . In their design, ansi b16.47 series a class 150 flanges tend to be bulkier, stronger and thicker, as compared to the  B Series of the ANSI B16.47 flanges. This is the reason for the ANSI B16.47 Series A flanges having an excellent performing  especially under loads of huge pressure, in the fields  where they are used in heavy-duty applications such as engineering and load handling equipment.

Series A  of the asme b16 47 flange dimensions will be stronger, heavier and thicker than their counterpart series B flanges, where the same pressure rating and size is concerned. Series B flanges will require more fasteners, albeit smaller ones, as compared to ansi b16.47 series a class 600 flanges. flange ANSI B16 47 Series A has the capacity to withstand more external load than that of flange ansi b16 47 b series.

The bolt circle diameter of the ASME B16 47 Series B flanges is smaller than that of ansi b16.47 series a class 300 flanges. A smaller bolt circle diameter in the flange results in the Series B ASME B16 47 flanges exhibiting lesser movement after being installed. In the in raised face type (RF), both Blind flanges as well as weld neck flanges, are defined in Series A and Series B.

Ring type joint (RTJ) flanges are only demarcated in Series A ASME B16. From a commercial perspective, flanges of ASME B16.47 Series tend to be much more costlier as compared to those  flanges of ASME B16 47 Series. Where new pipelines or equipment’s are concerned, most piping designers or  end users prefer use ASME B16 47 Series A flange. But when there is a need for non-critical piping design, refurbishment or a replacement job, then the popular choice are flanges of Series B asme b16 47 blind flange dimensions.

As the name very clearly indicates, the ASME B16.47 slip on flanges are a type of pipe flanges that can be slipped on over a pipe. This category of flanges are produced in such a way that the inside diameter of the flange, is a bit larger as compared to the outside diameter of the pipe. These slip on flanges are connected to the pipe, with the help of a fillet weld at the bottom and at the top of the flange. Slip on flanges of ASME B16.47 are basically provided with either a flat face or a raised face. In applications that require the use of ASME B16.47 with a raised face, pipe flanges under 400# with a standard height of 1/16 inch is used. And for slip on flanges of asme b16 47 flanges of 400# and higher classes , the standard raised face height is 1/4".
