Introduction of ASME B16.47 flanges

We are a manufacturer,supplier and exporter of ASME/ANSI B16.47 flanges,which are large diameter flanges that are further classified into ASME B16.47 Series A flanges and ASME B16.47 Series B flanges.MSS SP-44 flanges are designated as ASME B16.47 Series A flanges,API 605 flanges are designate as ASME B16.47 Series B flanges.

ASME B16.47 Series A flanges are upscale yet thicker,stronger and bulkier in their design than ASME B16.47 Series B flanges,thus they perform well when equipped under massive pressure loads,with service applications in the load handling equipment and heavy-duty engineering services.We supply ASME B16.47 Flanges in metals like carbon steel,stainless steel,alloy steel, covering classes 75,150,300,400,600,and 900.
