Material for Trifluoroacetic acid (TFA) transport tank

[ZGZtanker]

We are quoting a tank for transport of Trifluoroacetic acid (TFA)(UN 2699)at ambient temperature.
I have not been able to find much information about recommended steel grades for the transport of this product, just a brief information in a Halocarbon MSDS.

Does anybody have some information about the corrosivity of this product with different grades of steel?

Best regards

You need to get with your local jurisdiction about any special shipping requirements for TFA. The material of construction should come from the customer or the producer of the TFA as it is very bad practice for a fabricator to select a material of construction for any reactive chemical.
This is not a recommendation for a material of construction but information given to assist you in resolving your problem. As I recall all of our equipment used with TFA was 316L Stainless Steel. I can't recall if 316L was used for the anhydrous form as most of our work with TFA was diluted when used in our process.
The manufacturer should have the MOC for transport since they can be held accountable if it causes any problems.

Again this is not a specific recommendation for fabrication but given as starting point in the search process. TFA isn't to be treated lightly as it is extremely irritating and very corrosive to the skin.
