Liquid Nitrogen Tank Need Do Annual Inspections

Liquid nitrogen is a liquid form of nitrogen formed at a low temperature. Nitrogen is usually a colorless, odorless gas. The storage containers used are different. The former is a liquid nitrogen tank and a dewar tank, and the latter is a nitrogen tank.

Liquid nitrogen tank generally refer to small static storage vessels that do not require pressurization. Therefore, annual inspections are not required. However, the differential pressure level gauge on the liquid nitrogen tank is required to be tested every year because if it is not inspected, it may affect the normal use of the liquid nitrogen tank.
