11) seal the outlet pipe of the cooler with a blind plate, and conduct a hydrostatic test on the cooler from the inlet pipe with an electric pressure test pump. During the test, the pressure shall slowly rise to the test pressure, which is 0.69mpa (the maximum working pressure is 0.55mpa), and the test time is 20min. Mainly observe the pressure maintaining condition and whether the cooler pipe has water leakage, and notify BYC Engineer for confirmation; for the hydrostatic test The water source is demineralized water. After the pressure test, the water shall be drained and dried.<br>
