Precautions for storage and transportation of large diameter spiral welded pipe

What are the precautions for storage and transportation of large-diameter spiral welded pipes? The following editor will introduce it to you.

1. Pipe packaging should be able to avoid loosening and damage during normal loading, unloading, transportation and storage.
2. If the buyer has special requirements for the packaging material and packaging method of the spiral steel pipe, it should be indicated in the contract; if not indicated, the packaging material and packaging method shall be selected by the supplier.

3. Packaging materials should meet relevant regulations. If no packaging material is required, it should meet the intended use and avoid waste and environmental pollution.

4. If the customer requires that the large-diameter spiral pipe should not have damage such as bumps on the surface, it can be considered to use a protective device between the pipes. The protective device can use rubber, hemp rope, fiber cloth, plastic, pipe cap and so on.
5. Thin-walled products can use tube support or tube outer frame protection measures. The material of the bracket and the outer frame is selected from the same steel material as the pipe material.

6. It is generally stipulated that large-diameter spiral pipes should be packed in bulk. If the customer requires bundling, it can be considered as appropriate, but the caliber must be between 159MM and 500MM. The bundled materials should be packed and clamped with steel belts, and each strand should be twisted into at least two strands, and should be appropriately increased according to the outer diameter and weight of the pipe to avoid loosening.

7. Products of fixed length may not be bundled.
8. If there are threaded buckles at both ends of the pipe, it should be protected by a thread protector. Brush lubricating oil or anti-rust agent on the thread. The two ends of the pipe are opened, and the nozzle protectors can be added at both ends according to the requirements.
9. If the large-diameter spiral pipe is put into the container, the container should be covered with soft moisture-proof devices such as textile cloth and straw mat. In order to prevent the pipe from being scattered in the container, it can be bundled or welded with a protective bracket outside it.
