How to prevent rust of seamless steel tube

　　Choosing the right warehouse for seamless steel pipes

　　(1) The warehouses where seamless steel pipes are kept should be selected in a clean and well-drained place away from factories and mines that produce harmful gases or dust. Remove weeds and all debris on the site and keep steel pipes clean.

　　(2) Do not stack in the warehouse with materials that are corrosive to steel pipes such as acids, alkalis, salts, and cement. Different types of steel pipes should be stacked separately to prevent confusion and prevent contact corrosion.

　　(3) Some small steel pipes, thin steel plates, steel strips, silicon steel sheets, small-caliber or thin-walled steel pipes, various cold-rolled, cold-drawn steel pipes, and high-priced and easily corroded metal products can be stored in the warehouse.

　　(4) Treasury should be selected according to geographical conditions. Generally, general closed warehouses are used, that is, warehouses with roofs and walls, tight doors and windows, and ventilation facilities.

　　(5) Treasury requires ventilation in sunny days, and close moisture-proof in rainy days, and often maintain a suitable storage environment.

　　Common methods to prevent rusting of seamless steel pipes are:

　　(1) Composition alloy to change the internal structure of iron. For example, chromium, nickel and other metals are added to ordinary steel to make stainless steel, which greatly increases the rust resistance of steel products.

　　(2) Covering the surface of iron products is a common and important method to prevent iron products from rusting. According to the composition of the protective layer, it can be divided into the following types:

　　a. Apply mineral oil, paint or fired enamel, spray plastic on the surface of iron products. For example: cars and buckets are often painted with paint; machines are often coated with mineral oil.

　　b. On the surface of steel, use a method such as zinc, tin, chromium, nickel, etc. These metal surfaces can form a dense oxide film to prevent iron products from contacting water and air and rust.

　　c. A dense and stable oxide film is formed on the surface of iron products by chemical methods to prevent iron products from rusting.

　　(3) Keeping the surface of iron products clean and dry is also a good way to prevent iron products from rusting.
