Forged Flanges

orbit engineering co. is an ISO manufacturer,  A  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 , Alloy Steel, Carbon Steel,Forged Flanges to the chemical units, Oil and refineries, shipbuilding, petrochemicals and gas processing and distribution centers.
