Methods to Prevent Wear and Tear on Spiral Steel Pipes in Industrial Projects

1. Spiral steel pipe packaging should prevent loosening and damage during normal loading, unloading, transportation, and storage.

2. If the buyer has special requirements for the packaging materials and methods of the spiral steel pipes, these should be specified in the contract; otherwise, the supplier has the option to choose the packaging materials and methods.

3. Packaging materials should comply with relevant regulations. If no packaging materials are specified, they should be suitable for the intended use, avoiding waste and environmental pollution.

4. If the customer requires that the spiral steel pipes not be subject to bumps or other damage on the surface, protective devices can be considered between the spiral steel pipes. Protective devices can use rubber, straw rope, fiber cloth, plastic, pipe caps, etc.

5. Thin-walled spiral steel pipes, due to their thin walls, can be protected with internal steel pipe supports or external frames. The materials of the supports and outer frames should be the same as the material of the spiral steel pipes.

6. National regulations stipulate that spiral steel pipes should be packaged in bulk. Bundling is optional if requested by the customer, but the diameter must be between 159mm and 500mm. Bundled materials should be secured with steel straps, each strap twisted into at least two strands, with the number of strands increased appropriately based on the outer diameter and weight of the spiral steel pipe to prevent loosening.

7. Fixed-length spiral steel pipes do not need to be bundled.

8. If the spiral steel pipe ends have threads, thread protectors should be used. Apply lubricant or rust inhibitor to the threads. For pipes with slits at both ends, end protectors can be added upon request.

9. When loading spiral steel pipes into containers, line the inside with soft, moisture-proof materials such as woven fabric or straw mats. To prevent the spiral steel pipes from scattering inside the container, they can be bundled or have protective supports welded to the outside.
