Steel sealed containers used for storing liquids or gases are called steel storage tanks. Steel storage tank engineering is an essential and important infrastructure in industries such as petroleum, chemical, grain and oil, food, firefighting, transportation, metallurgy, etc
Carbon steel storage tanks are instruments used to hold non corrosive powder materials, industrial concentrated sulfuric acid, industrial caustic soda, neutral water solutions, oils, and other substances.
Carbon steel storage tanks are used to store concentrated sulfuric acid:
At a certain temperature, the corrosion rate of dilute sulfuric acid on carbon steel increases with the increase of concentration, and after reaching a certain concentration, the corrosion rate sharply decreases with the increase of concentration. For concentrated sulfuric acid with a concentration of over 80% and a temperature below 60 ºC, carbon steel and cast iron have good corrosion resistance, but they are not suitable for flowing sulfuric acid. A flow velocity exceeding 0.67m/s can cause turbulent corrosion, especially at the inlet and outlet positions of pipelines.
Concentrated sulfuric acid with a mass fraction greater than 70% can cause passivation when it encounters iron. Concentrated sulfuric acid will oxidize the surface of the steel, forming an oxide layer. Due to the low water content in concentrated sulfuric acid, there are no free ions. The oxide layer will no longer be corroded by oxidation. So using carbon steel storage tanks is completely acceptable, but a certain corrosion allowance must be left.
Due to the water absorption of concentrated sulfuric acid, it is necessary to pay attention to moisture prevention when storing in carbon steel tanks. Desiccants can be added to the breathing line of the tank, and nitrogen sealing can be added to large carbon steel tanks to isolate water vapor.
Carbon steel storage tanks are used for storing concentrated sulfuric acid and are closely related to other usage conditions.
Xinkaihe carbon steel storage tanks, plastic storage tanks without welds, automobile transport tanks, ship transport tanks and other series of products are formed in a one-time mode by internationally advanced rotational molding technology. The products have the advantages of one-step forming without welding seams, impact resistance, aging resistance, light weight, no leakage, acid and alkali resistance, long service life, and meet health standards
