Our project designed one aboveground fire water system, I have one question about thermal PSV protection for the firewater main header (no insulation, max ambient temperature =30C, max). I understand water expands when temperature increase and thus thermal PSV need. But, I checked other...
Hello All,
There is one 20 years pump without performance curve. We need the pump's shutoff head to evaluate the piping PSV set point. In data sheet performance section show max head @ rated impeller showed as 680 ft. Is this equal to shutoff head?
Thanks,
