Choosing material for liquid sulphur handling

[sathish66633]

We are choosing material for a valve for our customer handling liquid sulphur in his plant. Please advise whether normal 316L is sufficient for the same. Is NACE requirement mandatory for liquid sulphur? This is a new requirement for us and we just want to make sure that 316L (1.4404) would not react/ deteriorate in sulphur medium.

Also we would like to know any other important factor that has to be considered while choosing material for sulphur/ H2S or similar sour media

Usually ductile or steel is used to handle pure molten sulfur even in pumps- lots of references after all its the basis of sulphuric acid production. Is there an external or internal reason to use 316L?

Carbon steel pipe and carbon steel valves with 12% Chrome trim or 316 trim has been used for decades for molten sulfur tranport.
