First, let’s discuss the storage methods and precautions for precision steel pipes.
Select 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 more expensive metal products, consider storing them in sealed storage, but ensure proper ventilation. Precision steel pipes should be protected with opaque coverings during storage to prevent rust and aging. The covering should be sturdy and reliable, ensuring ventilation and preventing water vapor from collecting on the surface. When storing, support them and keep them at a certain distance from the ground to ensure proper ventilation. When stacking, pay attention to the number of layers to avoid localized stress on the pipe ends and damage to the anti-corrosion coating. Precision steel pipes should also be pickled, using both chemical and electrolytic methods. Chemical cleaning can thoroughly clean the surface, but may not remove dirt in fine cracks.
Next, let’s explore methods to extend the life of precision steel pipes.
1. We need to know how to prevent rust. Cleaning the surface of precision steel pipes is also important, using solvents or emulsions to remove oil and dust. 2. We need to understand the uses of precision steel pipes and what to do after maintenance. Precision steel pipes are used in the manufacturing of machinery and equipment, automobiles, aerospace, and other fields. To extend the life of precision steel pipes, we can choose suitable storage sites and warehouses, keep the pipes clean, avoid stacking them with corrosive materials, and stack different types of steel pipes separately.
3. Proper stacking: Stack materials by type and specification, and stack different types separately to prevent mixing and cross-corrosion. The bottom of the stack should be elevated, solid, and flat to prevent moisture and deformation. Steel sections stacked outdoors must be placed on wooden pads or stone blocks, with a slight slope to facilitate drainage. Ensure that the materials are placed straight to prevent bending and deformation. A clear passage should be left between stacks. Inspection paths are generally 0.5 meters long, and access paths are generally 1.5 to 2.0 meters wide, depending on the size of the materials and the transportation machinery.
4. Protective packaging and protective layers are important measures to prevent rust. The preservatives or other coatings and packaging applied to steel mills before leaving the factory must be protected during transportation and loading and unloading to prevent damage, which can extend the storage period of the materials. Before storage, materials must be protected from rain and impurities. Materials that have been exposed to rain or soiled should be cleaned using different methods depending on their properties. For example, a wire brush can be used for materials with high hardness, while cloth, cotton, etc. can be used for materials with low hardness. After storage, materials should be inspected regularly. If rust is found, the rust layer should be removed. For high-quality steel pipes, precision steel pipes, alloy steel sheets, thin-walled pipes, high-frequency welded steel pipes, alloy steel pipes, etc., after rust removal, both the inner and outer surfaces must be coated with rust-proof oil before storage. Steel pipes with severe rust should not be stored for long periods of time after rust removal and should be used as soon as possible.
