1.
Spiral steel pipes with fixed lengths can not be bundled.
2. If the two ends of the
spiral steel pipe have threaded buckles, they should be protected by thread protectors. Apply lubricating oil or rust inhibitor to the thread. Both ends of the
spiral steel pipe are broken, and pipe protectors can be added at both ends according to the requirements.
3.
Spiral steel pipe packaging should avoid loosening and damage during normal handling, transportation, and storage.
4. If the customer requires that the
spiral steel pipe should not have bumps and other damages on the surface, it can be considered to use a protective device between the
spiral steel pipes. The protective device can use rubber, grass rope, fiber cloth, plastic, pipe cap, etc.
5. The thin-walled
spiral steel pipe can be supported by the inner tube or protected by the outer frame of the tube due to its thick wall and thin wall. The material of the bracket and the outer frame adopts the same steel material as the
spiral steel pipe.
6. If the buyer has special requirements for the packaging material and packaging method of the
spiral steel pipe, it should be specified in the contract; if not specified, the packaging material and packaging method can be selected by the supplier.
7. Packaging materials should comply with relevant regulations. If no packaging material is required, it should meet the intended purpose and avoid waste and environmental pollution.
8. The state stipulates that the
spiral steel pipe shall be in bulk. If the customer requires bundling, it can be considered as appropriate, but the caliber must be between 159MM and 500MM. The baled materials are packed and fastened with steel belts, each of which should be twisted into at least two strands, and should be appropriately increased according to the outer diameter and weight of the
spiral steel pipe to prevent loosening.
9. If the
spiral steel pipe is put into the container, the container should be covered with soft moisture-proof devices such as textile cloth and straw mat. To scatter the
spiral steel pipe in the container, it can be bundled or welded with protective brackets on the outside of the
spiral steel pipe.
