What material is the silo on the urea packaging line made of? Urgently needed.
304 grade, or above 304L material
It is made of 304 material; what is its service life? Is it feasible to use carbon steel instead? How long is the service life?
Using 304 material is sufficient; materials such as 304L or higher are a bit of a waste. Personal opinion, for reference only.
Composite panel, carbon steel on the outside, with a thin lining plate (304).
Composite panel, with carbon steel on the outside and a thin lining plate (304). Is there any specific manufacturer?
It is recommended to use 304 material throughout; composite panels are too troublesome! ! Carbon steel used for the outer surface is also prone to corrosion and rusting! !
The 304 version will work fine for 20 years
Carbon steel can also be used; our company uses carbon steel. Cleaning the wet material after urea granulation is very troublesome, so for new urea production facilities, stainless steel should be used.
In dry regions in the north, carbon steel might be a viable option. In humid areas in the south, it is not advisable to use carbon steel.
Reply to 10# lxq700918: I agree with the moderator’s principle of adapting measures to local conditions; the material used to construct the urea storage tank should be determined based on the actual conditions in that area.
