Failure Analysis and Preventive Measures of Chemical Storage Tanks

Chemical storage tanks are one of the important equipment in the chemical production process, used to store various chemical substances. Due to long-term use and environmental factors, chemical storage tanks may experience various failure problems such as corrosion, leakage, bulging, etc. These failure issues not only affect the normal operation of chemical production, but also cause serious pollution to the environment. Therefore, analyzing the failure of chemical storage tanks and proposing corresponding preventive measures is of great significance for the stability and stability of chemical production.

1、 Failure Analysis of Chemical Storage Tanks

1. Corrosion failure

Corrosion of chemical storage tanks is one of the common failure problems. Due to the acidic, alkaline, and salt properties of the chemicals stored in chemical storage tanks, these substances can corrode the metal surfaces of the tanks during storage. In addition, the environmental conditions in which chemical storage tanks are located can also have corrosive effects, such as temperature, humidity, oxygen, etc. Corrosion can cause thinning of the wall thickness, uneven surface, and even perforation and leakage of chemical storage tanks.

2. Leakage failure

Leakage is another common failure problem of chemical storage tanks. Due to poor sealing performance of chemical storage tanks or loose pipeline connections, chemical substance leakage may occur. Leakage not only directly causes the loss of chemical substances, but also pollutes the environment and affects the normal operation of chemical production.

3. Drum failure

During the use of chemical storage tanks, surface bulges may occur due to poor internal gas emissions or excessive external pressure. Bulging can lead to a decrease in the load-bearing capacity of chemical storage tanks, and in severe cases, may even cause tank rupture.

2、 Preventive measures for chemical storage tanks

1. Choose corrosion-resistant materials

For the problem of corrosion failure, corrosion-resistant materials can be used to manufacture chemical storage tanks. For example, materials such as stainless steel and high-strength alloys have good corrosion resistance, which can reduce the corrosion of chemical substances on storage tanks. In addition, anti-corrosion coatings, cathodic protection and other technologies can be used to enhance the corrosion resistance of chemical storage tanks.

2. Strengthen sealing performance

To address the issue of leakage failure, the sealing performance of chemical storage tanks can be strengthened. (1) Choose high-quality sealing materials and components, such as fluororubber, polytetrafluoroethylene, and other materials with excellent corrosion resistance. (2) Regularly inspect and repair seals, replace damaged seals in a timely manner, and ensure good sealing performance. (3) Online leak detection systems and other technological means can also be used to promptly detect leakage issues.

3. Reasonably design the structure

To address the issue of drum failure, the structure of chemical storage tanks can be designed reasonably. For example, in tank design, the location and quantity of exhaust and drainage ports should be considered to ensure timely discharge in case of poor gas emissions. In addition, reinforcing ribs or support structures can be added outside the storage tank to improve its load-bearing capacity.

4. Regular inspection and maintenance

Regular inspection and maintenance of chemical storage tanks is one of the important measures to prevent failure. The inspection content includes tank wall thickness, surface condition, sealing performance, etc. Any problems found should be dealt with in a timely manner. The maintenance includes cleaning, lubrication, and replacement of seals to ensure the normal operation of the * * * storage tank. At the same time, pressure testing and leak detection tests need to be conducted on the storage tank to ensure stability.

5. Establish and improve management systems

Establishing a sound management system for chemical storage tanks is one of the important measures to prevent failure. The management system includes usage regulations, operating regulations, maintenance regulations, etc. By establishing a sound management system, the use and maintenance behavior of chemical storage tanks can be standardized. At the same time, it is necessary to train and assess operators to improve their operational skills and safety awareness.
