Matters Need Attention When Using Pressure Vessels

The inspection dynamic monitoring is an important means during the operation of the pressure vessel  . The purpose is to timely detect the abnormal state appearing on the operation or on the equipment, and take corresponding measures to adjust or eliminate it to prevent the expansion and continuation of the abnormal situation and ensure The container runs safely.

1.  check safety devices , accessories, auxiliary equipment and control equipment frequently to ensure that these equipment can perform normally.

2. Check all accessories are properly installed and  the leakage of interface  

3. For the quick-opening type pressure vessel,  the interlocking linkage function of the quick opening door can not be opened until the internal pressure released completely  and the safety interlocking device disengaged .

4. To ensure the safe operation, the pressure should not exceed the maximum working pressure 5. Check the safety valve and pressure gauge frequently for failure, and check whether it is sen t to inspected according to the regulations. The safety valve is calibrated at least once a year and the pressure gauge is calibrated every six months. Before the installation, the new safety valve should be installed according to the use of the pressure vessel.

6. When the maximum working pressure is lower than the source pressure, a pressure reducing valve must be installed on the pipeline which leading to the inlet of the pressure vessel.

If the pressure reducing valve cannot guarantee reliable operation due to the medium condition, the regulating valve can be used instead of the pressure reducing valve. Safety valves and pressure gauges must be installed on the low pressure side of the pressure reducing valve or regulating valve.

7. repairs can not be allowed when there is pressure inside the pressure vessel
