Oxygen, Nitrogen, Argon Storage TankWhat kind of anti-corrosion coating is used? How is it maintained?

The reason why the oxygen, nitrogen, and argon storage tank has anti-corrosion functions is that both the outer and inner sides of the tank are coated with anti-corrosion paint, selecting different anti-corrosion coatings for different parts. The inner and outer surfaces of the oxygen, nitrogen, and argon storage tank usually use light-colored non-carbon conductive anti-static anti-corrosion paint, which solves the pitting phenomenon caused by the previous use of carbon conductive anti-static paint, which does not last long.

With the development of technology, the emergence of lightweight non-carbon anti-static anti-corrosion paint can handle this corrosion pit phenomenon. Four layers of EP-2000 non-carbon anti-static anti-corrosion paint are applied inside and outside the tank. Four layers of EP-2000 non-carbon anti-static anti-corrosion paint are applied, with two layers of primer and two layers of topcoat.

　　Oxygen, Nitrogen, Argon Storage TankThe exterior uses GR thermal insulation reflective paint, which has weather resistance and stain resistance, and serves to insulate and cool down against high external temperatures, reducing the external temperature by 5-10 degrees.

For the inner and outer bottom plates of the oxygen, nitrogen, and argon storage tank, water-based lithium silicate zinc-rich paint is selected, which has good anti-corrosion effects, does not affect welding construction, is environmentally friendly, and is easy to apply, providing cathodic protection for the tank bottom plate. Two layers, with a thickness greater than 80 m; dry film thickness greater than 160 m of two layers of epoxy coal tar topcoat.

This is the paint selected for the oxygen, nitrogen, and argon storage tank. Anti-corrosion paint is very important for the oxygen, nitrogen, and argon storage tank. If the anti-corrosion is not done well, it will directly affect the application and service life of the tank.

The protection and maintenance of the oxygen, nitrogen, and argon storage tank is a very important aspect. Generally speaking, the maintenance cycle of the oxygen, nitrogen, and argon storage tank is different. The medium repair period is 60 to 120 days, and the major repair period is 12 months, or one year.

During the medium repair period, the appearance, valves, coils, etc. should be inspected and organized, and the anti-corrosion layer and insulation layer should be repaired to ensure normal operation. During the major repair period, in addition to the inspections during the medium repair, the interior of the tank should also be checked. If cracks or corrosion are found, repairs should be made, or the cylinder joints should be replaced. Moreover, after treatment, a test should be conducted to see if the problem has been resolved.

After the oxygen, nitrogen, and argon storage tank is repaired and passes inspection, anti-corrosion and insulation can be carried out.

　　Oxygen, Nitrogen, Argon Storage TankSafety precautions for protection and maintenance include:

(1) If flammable gases or liquids are stored, appropriate fire-fighting equipment should be provided. Smoking and open flames are strictly prohibited inside the tank.

(2) Before repairing the tank, the power supply of related electrical equipment should be cut off, and corresponding procedures should be followed.

(3) After the medium in the tank is emptied, the inlet and outlet valves should be closed, and blind plates may need to be set up, disconnecting the connected pipelines or equipment and adding isolation signs.

(4) A work permit should be obtained when working inside the tank.

(5) When entering the tank to clean toxic or corrosive residues, operators should wear protective gear.

(6) When working inside the tank, someone should supervise and provide contact information for emergencies.

(7) After pressure testing the tank, drainage should be connected to the atmosphere to prevent the tank from being evacuated and the pressure from becoming too high.
