Carbon steel storage tanks are relative to stainless steel storage tanks, and the difference from stainless steel storage tanks lies in the material. Generally, carbon steel storage tanks are made of carbon steel materials, such as Q235B and Q345R. For carbon steel storage tanks, the inner surface is usually pickled and passivated, and the outer surface is first painted with anti – rust paint and then with finish paint. The finish paint can be selected according to the corporate culture. Most carbon steel storage tanks are pressure storage tanks. Generally, due to relatively high pressure, the wall thickness is relatively thick, but the price differs greatly from that of stainless steel storage tanks with the same wall thickness, and it is generally cheaper than stainless steel storage tanks. For non – clean occasions and occasions where there is no corrosion to materials, such as petroleum, chemical industry, sewage treatment, etc., choosing carbon steel storage tanks is economical and practical.
The volume of carbon steel storage tanks ranges from 0.1m³ to 500m³, and they are designed and manufactured according to user requirements. Carbon steel storage tanks are made of carbon steel materials, with vertical or horizontal structures, upper and lower elliptical heads or flat bottoms, and are equipped with manholes, exhaust ports, liquid inlet and outlet nozzles, pressure gauges, safety valves, etc.
Designed and manufactured according to the actual needs of customers, carbon steel storage tanks are generally large – scale storage tanks, mostly used in the petrochemical industry. The interfaces adopt standard flange connections, which are safe and reliable. Anti – corrosion treatment can be done inside the tank, and anti – corrosion and paint treatment can be done outside the tank.
Carbon steel storage tanks have thick walls and heavy weights, suitable for use in non – sanitary occasions. They can also be lined with pe, pp, or tetrafluoroethylene for anti – corrosion treatment and can store some corrosive materials, such as hydrochloric acid, sulfuric acid, etc. Carbon steel storage tanks generally belong to pressure vessels, and the pressure can be designed according to customer requirements, including all safety reports and flaw detection reports.
