You are correct, the standard temperature rating for the gasket material is higher than our design conditions, so originally we had thought there would be no issue with the gaskets. The problem we ran into was Victaulic only rates their fittings for 150F with nitrile gaskets.
Thank-you all for your response. Design issues as mentioned above were considered and the only issue I had was whether or not we were violating a code issue with the spec break/lower design temp on the temporary piping, the new design temp is still above the max operating temp so we still have...
pennpiper,
-the bypass is only around the cooling units, there are 2 banks of fin fans we will be bypassing one bank at a time, the temporary system is sized to handle one half of the cooling load.
-The bypass line is NPS 12
-the system is designed to B31.3 - design conditions are 2800 gpm...
I am looking into a temporary bypass of a cooling water system to facilitate repairs on the cooling units. The current design temperature on the cooling water system is much higher than actual operating conditions (installed circa 1970). We wanted to use Victaulic fittings for the temporary...
