1. Avoid the pipe from bending or deforming during the carriage.
2. Seal the openings of the copper pipe with end cover or adhesive tape during the storage.
3. Place the coil upright to avoid compressing deformation due to self weight.
4. Use wooden support to ensure that the copper pipe is higher than the ground, so as to make the pipe
dust-proof and water-proof.
5. Take dust-proof and water-proof measures at both ends of the pipe.
6. Keep the pipes on special bracket or bench at specified place on the construction site.
