The chemical polishing of large medium-sized stainless steel flanges is to make the flange surface bright smooth according to standard dissolution. In the whole process of chemical polishing, the passivation treatment air oxide film the air oxide film continue to dissolve on the surface of large medium-sized stainless steel flanges, the former is stronger than the latter. Because of the inconsistency of the external economy on the surface of large medium-sized stainless steel flanges, the economic protruding parts on the surface are preferentially dissolved, the dissolution rate exceeds the dissolution rate of the recessed parts; the dissolution of the film the production of the film are carried out separately beginning to end, only the rate is different As a result, the surface roughness of the large medium-sized stainless steel flanges of steel is smoothed, a smooth bright surface is obtained. Grinding polishing can fill the surface skin pores, scratches other surface defects, thereby increasing fatigue friction resistance erosion friction resistance.
Flange, also called flange boss plate flange. Flange is a part that connects between shaft shaft, which is used for the connection between the ends of the pipe; it is also effective in the import export trade of machinery equipment, is used for the connection between two machinery equipment, such as the reducer flange. Flange connection flange connection head refers to a detachable connection that is connected by flange, gasket anchor bolt as a set of sealing structure. Pipeline flange refers to the flange used in pipeline equipment, when used on machinery equipment refers to the import export trade flange of machinery equipment. There are holes on the flanges, anchor bolts make the two flanges tightly connected.
