The thickness of Closed Galvanized Barrel is crucial to ensure its corrosion resistance.1. Basic characteristics of galvanized steel barrelsGalvanized steel barrels are coated with a layer of zinc on the surface of the steel barrel to provide additional corrosion protection. The zinc layer can prevent the steel barrel from direct contact with corrosive substances such as oxygen and moisture from the outside, thereby extending the service life of the steel barrel.2. Selection of the thickness of galvanized steel barrelsThe thickness of the galvanized steel barrel directly affects its corrosion resistance. Generally speaking, the thickness of galvanized steel barrels is between 0.5mm and 1.5mm, which is the most common specification range. However, the specific selection of the thickness of the galvanized steel barrel needs to consider the following factors:Use environment:If the steel barrel will be used in a highly corrosive environment (such as chemical, pharmaceutical, food and other industries), a thicker galvanized layer needs to be selected to enhance its corrosion resistance.In extreme environments such as strong acids and alkalis, the galvanized layer may need to reach 7 to 10 mm to ensure that the steel barrel can be used for more than 15 years without rusting.Galvanizing process:The thickness of galvanized steel barrels from different manufacturers and processes may vary. Therefore, when choosing a galvanized steel barrel, you need to understand its galvanizing process and quality control standards.Material thickness:The material thickness of the steel barrel itself will also affect the thickness of the galvanized layer. Generally speaking, the thicker the material, the thicker the zinc layer required.3. Evaluation of anti-corrosion performanceIn order to ensure that the Closed Galvanized Barrel has sufficient anti-corrosion performance, the following measures can be taken for evaluation:Galvanized layer uniformity: Check whether the galvanized layer is evenly covered on the surface of the steel barrel to avoid leakage or thin plating.Galvanized layer thickness detection: Use professional measuring tools to detect the thickness of the galvanized layer to ensure that it meets the design requirements.Corrosion resistance test: Corrosion resistance tests are performed by simulating the actual use environment, such as salt spray test, acid spray test, etc., to evaluate the corrosion resistance of galvanized steel barrels.In order to ensure that the Closed Galvanized Barrel has sufficient anti-corrosion performance, it is necessary to select a suitable galvanized layer thickness according to the specific use environment and requirements. Generally speaking, in a highly corrosive environment, a thicker galvanized layer is required to enhance its anti-corrosion performance. At the same time, by checking the uniformity of the galvanized layer, detecting the thickness of the galvanized layer, and conducting corrosion resistance tests, it is possible to evaluate whether the anti-corrosion performance of the galvanized steel drum meets the requirements.
