CONSTITUTION:A method for checking leak from double shut-off gas valves 1, 2 is such that after pressure in detection objective chamber is set at a predetermined pressure valve, when the pressure value does not reduce to the second set pressure value within a time shorter than a predetermined...
PURPOSE:To enhance checking sensitivity and to make it possible to set time constant for checking arbitrarily by obtaining the partial pressure and the concentration of gas-leak checking gas by subtraction between introduced gas and introduced atmosphere at every specified time, and integrating the resu...
When work was complete and the LOTOs released, plant personnel would restart the unit and hope for the best. Depending on the success of the repairs, this repair evolution could have taken several hours and caused missed dispatch schedules. The best practice described below and the plant’s me...
