How to Store Precision Steel Pipes to Prevent Rust and Extend Service Life

First, choose a suitable storage location that is clean, well-ventilated, and free of debris and harmful gases. Keep the steel surface clean to prevent corrosion. For high-priced metal products, consider storing them in a sealed container, but ensure adequate ventilation. For precision steel pipes, use an opaque cover for protection to prevent rust and aging. The cover must be sturdy and reliable, ensuring ventilation and preventing water vapor buildup on the surface. Provide support during storage, maintaining a certain distance from the ground to ensure ventilation. Pay attention to the number of layers when stacking to avoid localized stress on the pipe ends and damage to the anti-corrosion layer. Simultaneously, we should also pay attention to pickling the precision steel pipes, using both chemical and electrolytic methods. Chemical cleaning can thoroughly clean the surface, but may not remove dirt from crevices.

First, we need to know how to prevent rust. Cleaning the surface of the precision steel pipes is also important; solvents or emulsions can be used to remove oil and dust.

Second, we need to understand the uses of precision steel pipes and what can be done after maintenance. Precision steel pipes are used in the manufacture of machinery, automobiles, aerospace, and other fields. To extend the lifespan of precision steel pipes, we can choose suitable locations and warehouses for storage, keep the pipes clean, avoid storing them with materials that are corrosive to steel, and store different types of steel pipes separately.

Third, proper stacking should be done according to type and specification. Different types of materials should be stacked separately to prevent confusion and cross-corrosion. The bottom of the stack should be raised, firm, and level to prevent the materials from getting damp or deformed. For steel sections stacked in the open air, there must be wooden pads or stone blocks underneath, and the stack surface should be slightly inclined to facilitate drainage. Care should be taken to ensure the materials are placed straight to prevent bending and deformation. At the same time, a certain passage should be left between stacks. Inspection passages are generally 0.5m wide, and access passages depend on the size of the materials and the transport machinery, generally 1.5 to 2.0m wide.

Finally, protective packaging and protective layers are important measures to prevent material corrosion. The anti-corrosion agents or other coatings applied by the steel mill before leaving the factory, as well as the packaging, must be protected during transportation and handling to prevent damage and extend the material's shelf life. Before warehousing, materials should be protected from rain and impurities. Materials that have already been rained on or soiled should be cleaned using different methods depending on their properties; for example, high-hardness materials can be cleaned with a wire brush, while low-hardness materials can be cleaned with a cloth or cotton. After warehousing, materials should be inspected regularly, and any rust should be removed. For high-quality steel, precision steel pipes, alloy thin steel plates, thin-walled pipes, high-frequency welded steel pipes, and alloy steel pipes, both the inner and outer surfaces should be coated with anti-rust oil after rust removal before storage. Severely rusted steel pipes should not be stored for extended periods after rust removal and should be used as soon as possible.
