propane tank to be converted to nitrogen tank
(OP)
The client wishes to convert his 18000 gallon (MAWP 250 psig)propane tank to a pure, free of water vapor, nitrogen tank. The maximum nitrogen pressure will be 125 psig.
The propane distributor indicated that this tank could become an illegal installation and I understand that since the tank has an ASME/NB stamp and number and lists the product as propane. This tank is in MA and MA has biennial requirement of inspections for air tanks but not for Nitrogen tanks.
Can a change in the tank useage and nameplate be made legally thu NB, or can the tank be used without a namplate?
Inputs will be greatly appreciated.

A)Thorough Internal Inspection cum cleaning with
B)various areas pressure jet washing and grit blasting
C)after that internal snapshots& UT,RT etc. etc.
may tell us about the subject tank's health in the first place
secondly there can be exposure from some entrained caustic or sulfide residues impacting the interior.(Caustic induced corrosion cracking issue)
After that Hydrostatic pressure test to the applicable standard's requirement under carefully controlled conditions for (personnel,nearby equipments) safety.
As Regards NEB's acceptance I can not say much, since I have little if any info in this connection.
Hope this is helpful in someway identifying health in a more comprehensive manner!
