.3.2.6 Moving and Storing of Pipes
1)
Do not break the pipes when they are moved to the construction site.
2)
Use end caps or adhesive tapes to seal pipe ends before the pipes are stored.
3)
The coil must be placed vertically. Otherwise, the coil may become deformed due to its own weight.
4)
Use wooden supports or acceptable substitutes to ensure that the copper pipes are placed at a place
higher than the floor. This can prevent the pipes from being stained by dust or water.
5)
Anti-dust and water-proof measures must be taken on both ends of pipes.
6)
Pipes must be placed on a specified shelve in the construction site, or be placed in a specified area
and looked after by a specified person.
