Arcellor Controls is leading ASME B16.47 Flange Manufacturers in India, large diameter flange further classified into ANSI B16.47 Series A and ANSI B16.47 Series B flanges. ANSI B16.47 Series A flanges are upscale yet stronger, thicker and bulkier in their design than ANSI 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 ANSI B16.47 Flanges in metals like Nickel, Hastelloy,Inconel, Stainless Steel, etc. in classes 75, 150, 300, 400, 600, and 900.
