Hydrochloric acid storage tanks often suffer from corrosion from internal and external media during daily use, which will shorten the normal service life of the hydrochloric acid storage tank. At the same time, corrosion will also contaminate the medium and have a negative impact on the quality of the medium. Moreover, corrosion problems will also cause the thinning of the tank and increase safety risks. Correctly analyzing the corrosion mechanism of hydrochloric acid storage tanks, finding out the causes of corrosion, and taking corresponding measures to prevent accidents are of great significance to the smooth operation of hydrochloric acid storage tanks. The hydrochloric acid storage tank of a certain company is mainly used to prepare desalted water, and is made of fiberglass. Due to the poor aging resistance of fiberglass, cracks can easily occur and lead to leakage, which pollutes the environment and seriously corrodes equipment. After the problem occurred, the company used a variety of repair methods, but failed to effectively control the leakage problem. The main equipment parameters are as follows: Fiberglass material, flange: DN50, leakage area: Flange and pipeline leakage, medium: 31% hydrochloric acid, room temperature. The current leading technology for FRP hydrochloric acid storage tanks is to use epoxy resin or vinyl ester to line the surface of FRP. However, both materials are difficult to resist corrosive media with complex compositions for a long time. They will soon directly lead to the anti-corrosion lining falling off, peeling and cracking, and hydrochloric acid will leak and cause pollution. Sole carbon nanopolymer material repair technology online repair: This material is a high-performance two-component polymer reinforced by carbon nanometers. It utilizes the material's unique mechanical properties and targeted repair processes to plug and repair corroded hydrochloric acid storage tanks online. Compared with using repair welding or epoxy resin linings, it has the characteristics of short repair time, low cost and good results. It reduces labor input and labor intensity of workers, while reducing hidden safety hazards at the construction site. The operation is simple and easy for workers to master.
