Exotic Materials
(OP)
Just a question because I know it is coming, What is API's stance on using an AL-6XN or 254 SMO material on a tank. I know Duplex is now widely accepted in harsh environments. If these materials are requested can the parameters in Annex X be used with them? Or will it just be per good engineering practice? Also can a tank have an API name plate with these materials?





RE: Exotic Materials
My understanding is that higher CPT and CCT may be a criteria for some storage media, which may be well taken care of by SDSS also.
The illustration on page 1 of the following article explains the differences between various alloys quite well for storage tanks..
