Can we use stainless steel pipework for flammable gases in a gas house?

Dear all,

 

We have found some information within the CSPA aerosol propellants safety manual that implies you can only use carbon steel schedule 80 pipework and forged steel fittings when dealing with vapors and liquids up to 350 psig.

 

Our preference would be to use stainless steel pipe and fittings.  This means we do not need to pain the pipework and gives us a much neater finish.

 

Is there a section with NFPA 30B (or other) that states what materials should be used for flammable propellants within a gas house?

 

Thanks in advance
