Copper Nickel ANSI B16.47 Series B Reducing Flange fall under the category of large diameter steel pipe flanges, of sizes NPS 26 to NPS 60. In their design, Stainless Steel B16.47 Reducing Flange are stronger, bulkier and thicker, as compared with Carbon Steel Flange B16.47 Series A and because of this Ductile Iron B16.47 Series A Flange perform extremely well under loads of huge pressure, in the fields of heavy-duty engineering and load handling equipment.
