Common anti-corrosion measures for forged flanges mainly include the following: Surface coating: Common anti-corrosion coatings include anti-rust paint, epoxy resin coating, polyether coating and so on. These coatings can form a protective film to isolate the contact between the flange and the external environment and play a role in corrosion prevention. Hot dip galvanizing: By dipping the surface of the flange into the melted zinc, the zinc reacts with the surface of the steel to form a zinc layer covering the surface of the flange. Hot dip galvanizing can provide good corrosion resistance and strong durability. Anodic protection: By coating a layer of anodic protection on the surface of the flange, the flange is protected as an anode through the current. This method is suitable for flange corrosion protection in special environment. Stainless steel material: The forged flange made of stainless steel itself has good anti-corrosion properties, without additional anti-corrosion measures. Stainless steel has high corrosion resistance and oxidation resistance, suitable for corrosive environment and special requirements of the working conditions. Anti-corrosion coatings: For flanges in special environments, such as acid and alkali corrosion, special anti-corrosion coatings can be used to protect them. These coatings have good corrosion resistance and chemical stability. The selection of appropriate anti-corrosion measures should be considered according to the engineering environment, medium properties, operating conditions and other factors. In the use and selection of anti-corrosion measures, it is recommended to refer to the relevant standards and specifications, and consult professional engineers or experts in the field of anti-corrosion.
