Issues regarding the lining of carbon steel containers with rubber
Thread Content
We had several resin columns with a diameter of 600 mm manufactured by an external contractor; to prevent corrosion, lining was applied inside them. When the equipment arrived, no problems were detected, but during installation bulges were found, forcing us to redo the lining work. I would like to know the standard procedures and acceptance criteria for lining. Could any helpful netizen recommend some standards or books? Thank you.
Gasket standard: HG 21503-93; similar problems have occurred before. The bulge is probably due to air getting mixed in during construction; it can be flattened by heating it with a hair dryer.

The bulging phenomenon is caused by problems in the lining process employed by the manufacturers.
It is not recommended. . . The current manufacturing processes are not very mature; in the past, our centrifuges had rubber linings, and we encountered the same problems as you
It’s a problem with the gasket installation; I’m not sure which type of gasket to use, and there are issues after installing it for a while It can only be said that the manufacturer does not pay attention to quality, which is why the issue is discovered only during installation.
