Anti-corrosion spiral steel pipes require careful handling not only during manufacturing but also during storage. This approach not only extends the service life of the pipes but also ensures that, even after long-term storage, they remain in as good condition as when they left the factory, making them easier to sell.

　　Anti-corrosion spiral steel pipes should not only be handled with care during production… Anti-corrosion steel pipe Damage can be prevented, and proper storage practices should also be observed. This not only extends the service life of the coated steel pipe but also ensures that, even after long-term storage, it remains in as good condition as when it left the factory, making it easier to sell.

　　1. Steel pipes of different grades must be stacked separately to prevent confusion and mutual corrosion. For high-pressure boiler tubes stored outdoors, wooden pallets or stone blocks must be placed beneath the stack, and the top surface should be slightly inclined to facilitate drainage. Additionally, ensure that the materials are laid out evenly and straight to avoid bending or deformation. The anti-corrosion coatings, platings, or packaging applied by the steel mill prior to shipment are critical measures for preventing surface rust on the steel pipes.

　　2. During transportation and handling, care must be taken to protect the pipes from damage, which helps extend their storage life. The protective coating on the steel pipe effectively safeguards its surface. Before storage, ensure that the pipes are kept dry and free from contaminants. For pipes that have been exposed to rain or become soiled, clean them using appropriate methods based on their material properties: use a wire brush for harder grades, and soft cloths or cotton for softer grades.

　　3. Before storage, anti-corrosion steel pipes must be protected from rain and contamination. Pipes that have been exposed to rain or soiled should be cleaned using appropriate methods based on their material properties: use a wire brush for harder grades, and a cloth or cotton rag for softer grades.

　　Anti-corrosion steel pipes have become widely recognized with their increasing use in numerous large-scale construction projects. During the anti-corrosion process, factors that influence the performance of the pipe’s protective coating include the layout of each processing step, equipment selection, surface quality, heating method, coating temperature, cooling approach, transmission accuracy, material properties, and inspection procedures. Poor control can result in defects such as inadequate adhesion, excessive thinness, cracking, or the formation of bubbles.
