    Corrosion resistance of 304SS to dilute 0.04% sulfuric acid

    thank you. I will find out what my clients line size is going to be. I will also check on the chloride issue. that is what made me concerned about 304 in the first place. May have them consider CPVC but this piping run has some potential support limitations which could be problematic.

    I have conflicting information on the requirment for a Pressure Safety Relief valve on the natural gas supply line after the regulator and before the automatic fuel shut off valves. Does anyone know which code lists that requirment? The piping between the reducing valve and the burner is...
