65% concentrated fuming sulfuric acid
Thread Content
For 65% concentrated fuming sulfuric acid, what metal material is best to minimize corrosion?
316L is the best choice; cost should be taken into consideration, but carbon steel is also an option. That’s how I made my choice :,lol
No, for acids with a concentration of 30-75%, 316L cannot be used; 904 should be used instead, although it is more expensive.
It refers to the administration of niacin. It’s not 65% dilute sulfuric acid.
115 Nicotinic acid (65 acid) – isn’t it called 65% nicotinic acid?
115 acid, which is what is commonly referred to as 65 niacin. Ordinary carbon steel is sufficient; there is no need to use stainless steel, unless there are special requirements regarding acidity.
For acid No. 65, carbon steel is sufficient, as we use carbon steel ourselves and the results are good enough
Personally, I think 16MN steel should be used. There is no need to use stainless steel or anything like that. Waste
The 65 here should refer to the Baume concentration, that is, 65Be'
65 acid refers to fuming sulfuric acid with a free SO3 content of 65%; when converted to sulfuric acid terms, this corresponds to an acidity of 115%, which is why it is commonly referred to as 65 acid in the industry. It is also sometimes called 115 acid.
What type of pump should be used to transport 65% fuming sulfuric acid?
