Question! Fuel oil storage tank
Thread Content
Do the fuel oil tank heating coils need to be pressurized regularly? Is it dangerous to use oil for pressure testing? Hydraulic pressure or air pressure? Urgent need, thank you! ! !
Generally, the steam coils for fuel do not require regular pressure testing; instead, such tests should be carried out during downtime, in line with the operation cycle of the installation. Since steam is usually used for heating, it is preferable to use steam for the pressure testing process as well!
Are there still any that use fuel oil?
It took a long time; there was no pressure buildup at any point. Heating is done via steam coils, and in the event of a leak, the oil’s properties will see a sudden increase in moisture content. When heated with heat transfer oil, the properties of the oil can also change suddenly. This situation doesn’t occur very often. During the completion inspection, pressure is applied to the coil; if pressure testing is to be carried out again, it is recommended to suspend work and wait until all materials have been cleared before performing the test.
It has never been depressurized since it was used. During the annual maintenance, it is possible to enter the tank to inspect the coils and perform steam leak testing.
