HGFF Group Co., Ltd. (HGFF) is an ISO manufacturer, Forged Flanges besides being their exporter to the Middle Eastern and European countries. A Stainless Steel Forged Flange can be defined as a metal disc, installed at the back of a tube, valve or any other object. It allows simple Fitting and replacement of a piping system. They undergo the forging process whereby mechanical, energy is applied to a steel flange, to change its shape when in a solid state. ANSI B16.5 Forged Flanges possess a better impact strength than Cast flanges and are stronger and reliable. We are suppliers of Titanium, Alloy Steel, Carbon Steel, Monel, Nickel, CuproNickel, Stainless Steel and Inconel Forged Flanges to the chemical units, Oil and refineries, shipbuilding, petrochemicals and gas processing and distribution centers.
