How to choose the gas storage tank correctly

Air storage tank is a kind of industrial equipment commonly used in industry to purify and compress air, and it is also one of the special safety equipment strictly regulated by the state.
The gas storage tank is a pressure vessel, produced by a designated pressure vessel factory, each with a vessel inspection certificate and accessories such as safety valve, drain valve, and pressure gauge.
The air storage tank can be used for multiple units or a single unit; it can reduce the air pulsation discharged from the piston air compressor; improve the continuity and pressure stability of the output air flow; further precipitate and separate the water and oil in the compressed air; ensure continuous Sufficient air volume is supplied.
The relative humidity in the atmosphere is generally as high as 65%. After compression and condensation, it becomes moist and saturated air, entraining a large number of liquid water droplets. It is the root cause of corrosion of equipment, pipelines and valves. In winter, icing can also block the passage of small holes in the pneumatic system. It is worth noting that even when separated from pure, pure saturated air, as the temperature decreases, there will still be condensation. About every 10°C drop, its saturated water content will drop by 50%, that is, half of the water vapor will be converted into liquid water droplets. Therefore, it is necessary to use a multi-stage separation filter device in the compressed air system or pretreat the compressed air into dry air with a certain relative humidity.
There are many brands of gas tanks on the market today. In order to ensure safety, the choice of gas storage tank plays a vital role.
First of all, we must choose products from large enterprises and well-known brands. The products of these enterprises not only strictly implement the "Steel Pressure Vessel" standard, but also have advanced production equipment, strict production process management, and high-quality raw materials. Although the price may be more expensive, it can guarantee that the product can be used with confidence when using it. In addition, products produced by enterprises that have passed various quality system certifications are also given priority.
The second is to look at the appearance. The appearance of a product reflects its class and value. Only regular and powerful manufacturers have advanced equipment guarantee and a good quality assurance system to ensure the grade of product appearance. The trademark of the high-quality gas storage tank is very obvious, and the brand of the gas storage tank can be clearly known 50 meters away from the gas storage tank. Close to the gas storage tank, the tank itself has bright colors, uniform surface treatment, smooth welds, and clear lines. It is recommended to buy new products.
The third is to look at the product nameplate. The nameplate should indicate the name and production date of the manufacturer and the supervisory inspection unit. Whether there is a seal of the supervisory inspection unit on the upper right corner of the nameplate, the product number, weight, volume, and the name of the product must be indicated on the nameplate. The maximum pressure, working pressure and pressure of the hydrostatic test, and the medium of the gas storage tank also need to be marked. There must be a product steel stamp number directly under the nameplate of the entire tank, and the steel stamp number must be consistent with the number on the nameplate. If you find that the two numbers do not match, do not buy.
The fourth is to look at the quality assurance certificate. According to relevant national regulations, each gas storage tank must be equipped with a quality assurance certificate. The quality assurance certificate is an important certificate to prove that the gas storage tank is qualified. Please do not buy without a certificate of quality assurance.
The fifth is to look at the qualifications of manufacturing companies. A powerful enterprise has qualifications and honors that ordinary enterprises cannot match. Although some small enterprises have a pressure vessel manufacturing license, the overall equipment is outdated and the management is not standardized. Avoid unnecessary trouble caused by enterprise qualification.
