Carbon steel high pressure flange is a flange whose body is made of carbon steel. Common materials are carbon steel A105, or Q235B, A3, 10#, 20#, Q345B, etc. The surface of carbon steel flange is electroplated or coated with antirust oil and sprayed with antirust paint to prevent rust.
Carbon steel high pressure flange is different from ordinary flange in thickness, bolts used are also different, and there are obvious differences in materials. The forging strength of high-pressure flange is much better than that of ordinary flange.
