1. Material Selection
Choosing the right steel: Steel pails are primarily made of low-carbon thin steel plates. Low-carbon thin steel plates have good plasticity and ductility, allowing them to adapt to deformation caused by temperature fluctuations to a certain extent.
Using surface treatment processes: Steel pails are typically treated with coatings and paints, such as galvanizing, galvanizing, and color coating. These surface treatments not only improve the corrosion resistance of the steel pail but also reduce the effects of thermal expansion and contraction.
2. Processing Optimization
Controlling the welding process: During the steel drum manufacturing process, the welding process has a significant impact on thermal expansion and contraction. Using appropriate welding processes, such as carbon dioxide welding and brazing, and controlling the welding temperature and time can reduce the thermal stress generated during welding, thereby minimizing the risk of thermal expansion and contraction.
Adding Ribs: During the steel pail body processing, ribs are added through processes such as rolling and expanding. Ribs increase the strength and rigidity of the steel drum, making it less susceptible to deformation during temperature fluctuations. 3. Environmental Control
Avoid Extreme Temperatures: Steel drums should be used and stored in environments with high or low temperatures, or those with large temperature differences. If such use is unavoidable, minimize exposure to extreme temperatures.
Indoor Storage: After filling, Steel Pails should be stored indoors whenever possible. The relatively stable indoor environment with minimal temperature fluctuations effectively minimizes the effects of thermal expansion and contraction on the drums.
4. Filling and Sealing
Control the Filling Temperature: When filling at high temperatures, wait until the contents have cooled to room temperature before tightening the large and small caps. This minimizes thermal expansion and contraction caused by temperature differences.
Ensure a Good Seal: The large and small caps on the steel drums must be properly tightened. A loose cap can easily cause leakage, while an overtight cap can damage the gasket and the cap itself, compromising the seal. A good seal prevents the effects of external temperature fluctuations on the drum interior.
5. Storage and Transportation
Scientific Stacking: Steel drums should be stacked upright, with a pallet at the bottom and a cushioning layer such as corrugated cardboard between each layer. This prevents the steel pail from being squeezed and deformed due to improper stacking.
Avoid open-air storage: Open-air storage exposes steel drums to natural factors such as wind, rain, and sunlight, accelerating aging and discoloration of the paint on the drum surface, exacerbating thermal expansion and contraction, and even causing leakage.
