Storage tanks should pay attention to the problem of anti-corrosion
- May 23, 2018 -

With the rapid economic development, the tank industry has also ushered in a period of rapid development. In particular, the use of various large-scale crude oil tanks has become more widespread today. At the same time, in practical applications, how to take effective protective measures to ensure its safe use, the most important of which is to control its corrosion problems.

 

In the process of carrying out antiseptic treatment, different methods can be adopted. For example, anti-corrosion coating can be used. This is mainly to isolate the metal part of the tank and the corrosive medium, effectively preventing it from being eroded, which is also anti-corrosion thereof. The first line of defense. Therefore, the construction quality of the coating becomes very important and directly related to the control effect of the corrosive medium.

 

In order to meet this control effect, many details need to be noticed during the actual construction process. The first is to do a good job of protection. Normally, the anticorrosion work of crude oil storage tanks is basically open-air construction. Considering that wind and sand will be relatively large, it is necessary to set up a fence around it, and the location of the coating operation should be set on the upwind outlet, and the downwind outlet should be located. Sandblasting operations can reduce the impact of wind and sand. It is important to remember that the paint coating area and sandblasting operations also need to be staggered with each other to avoid sandblasting affecting the quality of the brushing.

 

The second is to pay attention to the problem of ventilation, and if necessary, take forced ventilation measures. In addition, control the temperature conditions. The temperature of the surface of the crude oil tank during brushing operations should be 3°C above the dew point temperature, and must not exceed 50°C. If the temperature of the steel surface is too high, bubbles will appear on the paint film, which will cause the adhesion to decrease. If the temperature is too low, the conventional paint can easily be frozen and hard to cure.

 

In addition to the need to consider the size of the environment's humidity. When the air humidity exceeds 85%, or when weather such as rain, snow, or heavy fog is encountered, surface corrosion protection of crude oil tanks may not be performed. Do not have dew on the surface of the crude oil tank when brushing.
