PE11_03

Piping systems tested hydrostatically shall be tested to a pressure of not less than 1.5 times the design pressure adjusted to 50oC, but in no case less than 7 barg. To determine the test pressure the following formula shall be used:-Pt = 1.5 P St. S. Where. Pt = minimum hydrostatic gauge pressure Pa (psig) P = internal design gauge pressure Pa (psig) ................
