Question: What material is suitable for the acid transfer pipeline inside the dry absorption triple tank?

May I ask: What material is suitable for the acid transfer pipe inside the dry absorption triple tank, especially one that can reduce corrosion between the gas and liquid phases? ?
Hehe, it seems that cast iron pipes have a good lifespan

If cost-effectiveness is a concern, acid-resistant cast iron can be chosen. Acid-resistant cast iron inner liners have been in use for many years, and we have also used high-silicon alloys in quite a few dry suction triple-tank systems in recent years
We used cast iron before, and it didn’t work very well; now we’ve switched to hard 4F, but the results are unknown. We’ll find out when we do the annual maintenance later
