5. Can we visit your factory?
--Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.

6.What's the different between ASME B16.47 series A vs series B?
--Physical attributes for Series A flanges are typically thicker in flange thickness, heavier in weight, and have large diameter bolt holes in comparison to Series B in the same size and pressure rating. Series B flanges generally have more bolt holes than are in smaller in diameter, generating the need for smaller bolting hardware.  It is important to note Series A and Series B flanges are non-compatible in bolting between each other.

Application of Series A flanges are normally used for industrial connectors such as valves, pumps and pipeline separations. Series B flanges are commonly used in pipeline application.

Price points for Series A flanges tend to be more expensive due to increased steel weight, whereas Series B consumes less steel weight therefore reducing cost.

In Conclusion: ASME B 16.47 Series A and Series B flanges are for large diameter applications for piping projects from 26" thru 60". Both Series can be manufactured using carbon, stainless, and other alloy materials.  Series A is a carryover from MSS SP44 and Series B from API 605, thus creating a more uniform standardization for the industry thru ASME B16.47.
