ASTM A182 F5 F11 F12 F91 flanges for high pressure hydraulic systems
With an industry-leading inventory of chrome moly alloy from leading manufacturers combined with a diverse set of secondary service capabilities, our team can supply flanges that will meet or exceed your critical project/plant specifications.
For alloy steel pipes, the material grades are usually: ASTM A335 P1/P5/P9/P11/P12/P22, A213 T1/T5/T9/T11/T12/T22/T91. At the beginning of the purchase of raw material billets, we will only purchase from large domestic steel mills. After the raw material billets enter the factory, we first conduct strict chemical composition testing and mechanical performance testing on its performance. Only two tests are acceptable. The A182 F22 alloy flange is a forged pipe fitting, and its performance will change during the forging process. After the forging is completed, the corresponding heat treatment process will be carried out according to the grade.
