In industrial production, carbon dioxide small cylinder is an important pressure vessel. Its pressure resistance and corrosion resistance are directly related to the safety and stability during storage, transportation and use. In order to ensure these key performances, the industrial-grade carbon dioxide small cylinder has been carefully considered and optimized in design and material selection.
From the design point of view, the industrial-grade carbon dioxide small cylinder adopts advanced pressure vessel design concepts. Its structure is compact and reasonable, and can withstand the pressure of the internal high-pressure gas to the maximum extent. In the design of the bottle body, seamless steel pipes or high-strength steel plates are used, and the overall strength and sealing of the bottle body are ensured through precise welding technology. In addition, the design of the bottle mouth is also crucial. It must not only ensure a close fit with the connecting parts such as valves, but also be able to withstand the instantaneous high pressure and impact caused by gas filling and discharge.
In terms of material selection, the industrial-grade carbon dioxide small cylinder mainly uses high-strength and corrosion-resistant alloy steel. These steels usually contain specific alloy elements, such as chromium, molybdenum, nickel, etc., which can significantly improve the strength and corrosion resistance of the steel. For example, 34CrMo4 steel and 37Mn steel are two commonly used industrial-grade carbon dioxide small cylinder materials, which not only have high strength, but also maintain good corrosion resistance in harsh environments. In addition, with the continuous advancement of materials science, some new high-performance alloy steels are gradually being used in the manufacture of carbon dioxide small cylinders to further improve their comprehensive performance.
In addition to the selection of steel materials, the corrosion resistance of industrial-grade carbon dioxide small cylinders is also closely related to its surface treatment process. During the manufacturing process, the surface of the cylinder usually undergoes a series of treatments such as sandblasting, pickling, and passivation to remove impurities such as oxide scale and oil stains on the surface and improve the corrosion resistance of the steel. At the same time, some special coating materials, such as epoxy resin and polytetrafluoroethylene, are also applied to the surface of the cylinder to further enhance its corrosion resistance and wear resistance.
In practical applications, the pressure resistance and corrosion resistance of industrial-grade carbon dioxide small cylinders have been fully verified. They can withstand internal pressures of up to tens of MPa and maintain good working conditions in various harsh environments. This not only ensures safety during storage and transportation, but also improves production efficiency and service life.
In summary, the pressure resistance and corrosion resistance of industrial grade carbon dioxide small cylinder are achieved through its advanced design concept and high-quality material selection. These measures not only ensure the safety and stability of the product, but also provide reliable guarantee for industrial production.
