Stainless steel flange designs the flange body and the socket as an integral structure, which avoids leakage due to the inability to align the welding port during welding and have a good sealing performance.

The methods to deal with rust on stainless steel flanges:

1. Clean with emery cloth and wire brush.

2. Using a tungsten steel shovel to shovel away large areas of rust.

3. Using a file to remove welding slag and other protrusions and various burrs.

4. Using a scraper and a wire brush to remove the rust on the corners.

5. Using a clean cloth, or a cloth dipped in solvent to clean and apply primer in time.

6. Note that the toughness coating film that has not expired can be retained, and the surface of the old paint should be roughened with emery cloth, and the defect of the coating film should be polished into an axe shape, and the paint should be painted directly after cleaning.
