Should schedule 40 ERW ASTM A53 piping be used for storm
Should schedule 40 ERW ASTM A53 piping be used for storm
(OP)
I designed a hospital roof helipad drain system around fuel gas code considering life safety issues of patients. I specified ASTM A53 schedule 40 steel pipe with welded joints (Schedule 40 ERW with welded joints was installed). Will the corrosion characteristic of this pipe support the storm water requirements? What would be the life expectancy of this pipe in a storm water application?

I work in the water treatment industry, and we have potable water lines in our pump plants that are still in service after 70 years. Stormwater, if it's super soft, may be a bit more corrosive. But the time to failure should be substantial.
You didn't state, but I'm assuming the pipe is black pipe. The A53 standard covers hot dipped galvanized as well.
