1.Spiral steel pipes of fixed length may not be bundled.
2.If the two ends of the spiral steel pipe are threaded, they should be protected by thread protectors. Apply lubricating oil or rust inhibitor to the screw. The openings at both ends of the spiral steel pipe can be equipped with nozzle protectors according to requirements.
3.Spiral steel tube packaging should be able to avoid loosening and damage during normal loading, unloading, transportation and storage.
4.If the customer requires that the spiral steel pipe cannot be bumped on the surface and other damages, consider using protective devices between the spiral steel pipes. The protective device can use rubber skin, straw rope, fiber cloth, plastic, pipe cap and so on.
5.Thin-walled spiral steel pipes can be protected by pipe inner support or pipe outer frame due to the thin wall. The material of the bracket and the outer frame must be consistent with the material of the spiral steel pipe.
6.If the purchaser has special requirements on the packaging materials and packaging methods of spiral steel pipes, they should specify them in the contract; if not specified, the packaging materials and packaging methods are selected by the supplier
7.The packaging materials should meet the relevant regulations. If packaging materials are not required, they should meet the intended use to avoid waste and environmental pollution.
8.The state stipulates that spiral steel pipes should be used in bulk. If the customer requires bundling, it can be considered as appropriate, but the caliber must be between 159MM and 500MM. The supplier uses steel belt to pack and festenz each track should be twisted into at least two strands, and increase appropriately according to the outer diameter and weight of the spiral steel pipe to prevent loosening.
9.When the spiral steel tube is loaded into the container; the container should be covered with soft moisture-proof devices such as v/oven doth and straw mat. In order to prevent the spiral steel pipe from scattering in the container; a protective bracket can be welded on the outside of the spiral steel pipe.
