Question asked by amrelhewie on Apr 9, 2017

I have installation at customer site Bulk oxygen installation 50,000L Tank and vaporization system to supply gaseous oxygen, the installation is near to LPG 30,000L Tank and the safe distance is in compliance with NFPA 58,

My question is what is the safe distance between the gaseous oxygen distribution pipeline and the LPG distribution pipelines?

If the oxygen gas pipeline is underground what are the specs of the trench for 1.5 inch pipe SS?
