Release time：

2025-12-23

Proper storage of seamless steel pipes is crucial for maintaining their material properties and extending their service life. The following table summarizes the core points to note, making it easy for you to quickly grasp the key points：

Storage precautions	Specific points
Site selection	Clean, dry, well-drained, far from corrosive sources, and indoor or outdoor sites should be chosen according to specifications
Stacking principle	Bottom padding and top covering, stack height and aisle width restrictions, classified stacking by variety and specification, first-in, first-out
Routine maintenance	Keep clean, conduct regular inspections, prevent water and moisture, and protect the original anti-corrosion coating
Special handling	Special requirements for removing pipe end protectors, controlling the number of stacking layers, and long-term storage

🏞️ Select the appropriate storage site

Choosing a suitable "home" for the steel pipe is the first and most crucial step.

• Environmental requirements:

The site must be clean and well-drained, and must be kept away from factories, mines and enterprises that produce a large amount of harmful gases or dust.

• Classified storage:

Based on the specifications and value of the steel pipes, determine their storage locations:

Open-air storage: Suitable for thick and heavy materials such as large sections of steel, rails, and large-diameter steel pipes.

Storage in material sheds:Small and medium-sized sections of steel, medium-diameter steel pipes, etc. can be stored in well-ventilated material sheds, but it is necessary to ensure that they are covered on top and padded at the bottom.
Storage in the warehouse: Small-diameter or thin-walled steel pipes, cold-drawn/cold-worked steel pipes, high-priced and easily corroded steel pipes (such as high-pressure boiler pipes) must be stored in the indoor warehouse. The warehouse should have tightly closed doors and Windows and be equipped with ventilation devices to ensure "ventilation on sunny days and moisture-proofing on rainy days".

• Isolation principle:

It is strictly prohibited to mix and stack with corrosive materials such as acids, alkalis, salts, and cement to prevent contact corrosion.

📦 Master the scientific stacking method

The correct stacking method not only ensures safety but also effectively prevents the deformation and rusting of steel pipes.

• Basic setup:

Whether indoors or outdoors, the bottom of the stack must be raised (for example, for cement floors, it should be raised by more than 0.1 meters; for mud floors, it should be raised by more than 0.2 to 0.5 meters). Wooden pads, flagstones, etc. should be used to ensure it is flat and solid, which is conducive to drainage and moisture-proofing.

• Stacking norms:

Safety dimensions: For manual operations, the height of the stack should not exceed 1.2 meters; for mechanical operations, it should not exceed 1.5 meters; and the width of the stack should not exceed 2.5 meters. Inspection channels (about 0.5 meters) and transportation channels (1.5-2.0 meters) should be left between stacks.
Clear classification: Stack the steel pipes separately by type and specification, and follow the principle of "first in, first out" to avoid confusion later or some steel pipes being stored for too long.
Prevent water accumulation: When stored outdoors, the stack surface should be slightly inclined. Section steel (such as channel steel) should be placed "with the opening facing down" (downward), while I-beams should be placed upright to prevent water accumulation and rusting in the grooves facing upwards.

🔧 Carry out meticulous daily maintenance

Daily maintenance is the key to ensuring that steel pipes remain in good condition during storage.

• Cleaning and Inspection:

Keep the warehouse clean and conduct regular inspections. If steel pipes are exposed to rain or soiled, they should be dealt with promptly - those with high hardness can be wiped with a wire brush, while those with low hardness can be wiped with a cloth.

• Protective anti-corrosion coating:

The anti-corrosion coating or packaging applied by the steel plant before leaving the factory is an important defense line for steel pipes. Be extremely careful during loading, unloading, transportation and storage to avoid bumps and damage to these protective layers.

• Special care for long-term storage:

If long-term storage is required (especially for anti-corrosion pipes) :

Use opaque coverings for protection to prevent rusting of the steel pipes and aging of the anti-corrosion coating. At the same time, ensure good air circulation inside the coverings to prevent the accumulation of water vapor.
It should be considered to remove the pipe end protector to prevent moisture from accumulating in the narrow space between the protector and the steel pipe and being difficult to evaporate.
Control the number of stacking layers to prevent the bottom steel pipes from undergoing radial plastic deformation (i.e., flattening) due to excessive pressure.

💎Summary

The core of storing seamless steel pipes is to provide them with a dry, clean and orderly environment, and to manage them meticulously as if they were important materials. Remember the principles of "the ground must be dry, the stacks must be stable, the categories must be clear, and regular inspections must be conducted."
