STRATEGIC BUSINESS UNIT FOR HYDRO STATIC TEST (H.T.B.U) H.T.B.U 7.8 Depressurization:- ¾ Start to depressurize the line after the data and information from the test has been approved. ¾ Depressurization of the pipeline shall be performed as a controlled operation, normally at a rate 1 Bar / Minute until the pressure has been reduced to 40% of the test pressure. Then depressurization should continue at a rate of less than 2 bars per minute to a hydrostatic head , and will be recorded. After that, after reaching to zero bars, close all valves on testing and venting head, and then disconnect all hoses, equipment and instruments. P a g e 20 ASSISTANT GENERAL MGR ENG.
