American standard flange also has an ANSI B16.5 standard number. Generally speaking, the flange size of B16.5 is less than 24. Inch, B16.47 flange is larger than 24 inch.<br> B16.47 A series is actually the name obtained after MSS SP44 standard flange is added to the American standard flange system, and B series is the name obtained after API 605 standard flange is added to the American standard flange system. This is MSS SP44, API Relationship between 605 flange and ANSI B16.47.<br> As for whether the A series flanges and B series flanges can be used universally, the answer is definitely not universal. This should be determined at the engineering design stage whether to choose A series or B series flanges, and A series and B series with the same pressure and size Flange, A series flange outer diameter, disk thickness, bolt hole diameter must be larger than B series, but the number of holes is less than B series, which results in a result, flanges of the same pressure size, B series is cheaper than A series Many, more economical, lower single weight, and lower redundancy conditions. Generally speaking, the selection of A series may require more requirements for the project to meet the requirements, the B series is more economical, the B series is slightly more used for ordinary pipelines, and the A series is slightly more used for gas pipelines. The two are generally not interchangeable.<br> The domestic standards SH3406 and HG20615 are derived from the ANSI B16.47 B series, which is the API 605 flange standard.<br> The above is the connection and difference between ANSI B16.47 A B series flanges.<br> Thanks for reading.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img alt=\"\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>American standard flange ANSI B16.47 has two series, namely A series and B series.
