A182 F9 F11 F12 F51 Alloy Flange for the structural valve
These are used in applications where the resistance required is not much and general corrosion resistance is required.
The a182 f9 material contains some amount chromium and molybdenum, both of which help in maintaining longevity thereby having a long service life. Weld Neck A182 F5 Flanges are easy to recognize because of its long tapered hub, which goes gradually over to the wall thickness from a pipe or fitting. ASTM A182 specification covers forged low alloy and stainless steel piping components for use in pressure system. Included are flanges, fittings, valves, and similar parts to specified dimensional standards.
