Description

A relentless effort to keep on reinventing and innovating our products and services has made us, HGFF Group Co., Ltd. a leading quality product dispensing company. Our customers are our priority. We are a
manufacturer, supplier and exporter of ANSI B16.47 Flanges, which are large diameter flanges that are further classified into ANSI B16.47 Series A and ANSI B16.47 Series B flanges. ANSI B16.47 Series A flanges are upscale yet thicker, stronger 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 SS ANSI B16.47 Flanges in metals like Inconel, Nickel, Hastelloy, Stainless Steel, etc. in covering classes 75, 150,
300, 400, 600, and 900.
