Can lined manholes be used for Class II and III stainless steel equipment with flammable, explosive and toxic media?
Basis: There is no prohibition in the flange standard, there is no prohibition in the manhole standard, and there is no prohibition in GB/T150. Why can't it be used?
GB/T151 is a medium that is highly hazardous and extremely hazardous and cannot be used. It cannot be used if there is a vacuum. It cannot be used if the design temperature is higher than 300℃.
Source GB/T 151-2014
study* Yes, but for storage tanks (such as ethylene oxide storage tanks) designed by the design institute, is it reasonable to use a lining ring for the manhole?
All standards are recommended! It should not be prohibited for lining plates to be used in explosive media! Many high-voltage equipment use liners! The price of the lining is high and the mechanical properties are low. It is not economical to use all lining materials and should not be promoted!
