Hi,

I am installing a drain piping system with an outer pipe for secondary containment to transport a mixture of 30% nitric acid, 1.5% hydrogen peroxide and Ni chloride and sulphate. I need some advice regarding the need to vent the secondary containment. Most of the H2O2 is degraded in the pickling process. Please advise!
