Anticorrosive Coating Thickness Gauge Tests Anticorrosive Coatings
According to the release of the movie "Heroes of Fire" adapted to the oil tank fire in the oil depot of Dalian Petro China Free Zone in 7.16 in 2010, it attracted the attention of many people in the society. The movie said that the explosive power of the oil depot was equivalent to the power of 20 atomic bombs, and it caused a heated discussion among the masses. The horrible power of oil blasts is alarming. Therefore, it is very important for society to effectively improve the safety index of large oil depots and reduce the probability of accidents. The safety of oil depots is affected by many factors, among which the anticorrosive coating of oil tanks is an important factor that cannot be ignored. However, it is difficult to judge the thickness and working strength of the anticorrosive coating of the oil tank by the naked eye alone, and the anticorrosive coating thickness gauge can easily solve the problem of distinguishing the quality of the anticorrosive coating and the thickness of the coating.
The so-called anti-corrosion coating refers to a coating applied on a metal surface to isolate it from surrounding media to control pipeline corrosion. It should have good electrical insulation and water resistance, strong adhesion to the surface of the pipeline, resistance to chemical damage and mechanical strength. Anti-corrosion coating is very important to protect the safety of oil tanks. Oil tanks have strict requirements on anti-corrosion coatings of oil tanks. Storage tank corrosion protection will be divided into internal corrosion protection and external corrosion protection. The inner wall coating of the storage tank must have good corrosion resistance and good solvent resistance. Secondly, the inner wall coating must be conductive to ensure the safety of the oil tank. And the outer coating of the oil tank should have a long service life. It is better to choose a primer with good rust resistance, a middle paint with good shielding, good gloss and color retention, good weather resistance, and easy to cover and repair.
Before the oil tanks are put on the market, oil tank manufacturers will conduct a comprehensive inspection of the oil tanks according to the provisions of the relevant inspection and evaluation of oil tanks, and use a digital ultrasonic thickness gauge to measure the thickness of the tank bottom plates, wall plates and floating boat roof plates. For the corrosion situation of the oil tank bottom plate, the magnetic flux leakage detector is used for magnetic flux leakage detection, and the corrosion condition on the back of the tank bottom plate is mainly detected. After the test, a detailed oil tank test report is formulated as the basis for determining the contents of the factory and future repairs.
Anticorrosive coating is closely related to the safety of oil tanks. Once the oil tank is corroded, the consequences are unthinkable. If we use an anticorrosive coating thickness gauge, we can both judge the pros and cons of the anticorrosive coating and detect the use of the anticorrosive coating. So as to reduce unnecessary disasters and avoid unnecessary losses. The prerequisite for all of this is to make a little investment, that is, to purchase an anticorrosive coating thickness gauge to regularly test the anticorrosive coating of the oil tank and repair it on time.
