There are requirements regarding the wall thickness of the gasket rings for equipment flanges according to NB/T47023, but it seems that no specific requirements exist for the linings. In my opinion, the material and thickness should be chosen based on the corrosion conditions of your equipment.
We usually use at least 3 mm; if the coating thickness of the device itself is greater, it is also possible to choose a thickness equal to that of the device’s coating.
