Common problems in stainless steel flange processing

Common problems in stainless steel flange processing:

1. Weld defects: The weld defects of stainless steel flanges are relatively serious. If manual mechanical polishing is used to make up for them, the resulting polishing marks will cause uneven surface and affect aesthetics.

2. Scratches are difficult to remove: overall acid pickling and passivation can cause chemical or electrochemical corrosion and rust in the presence of corrosive media, and cannot remove impurities such as carbon steel and spatter that adhere to the surface of stainless steel due to scratches and welding spatter.

3. Uneven polishing and passivation: After manual polishing and polishing, acid pickling and passivation treatment are carried out, making it difficult to achieve uniform and consistent treatment results for workpieces with large areas, and cannot achieve an ideal uniform surface. And its drawbacks include high labor costs and high auxiliary material costs.
