Stacking requirements for ductile iron pipe fittings

1. The principle of stacking is to stack according to the variety and specification under the condition of stable stacking and high quality. Different varieties of materials should be stacked separately to prevent confusion and mutual corrosion.

2. It is forbidden to store items that are corrosive to steel near the stacking position.

3. The bottom of the stack should be raised and leveled to prevent the material from being damp or deformed.

4. The same materials are stacked according to the order of storage, and the ductile iron pipe is easy to implement the principle of first move.

5. The profiles stacked in the open air have wooden mats or strips below, and the stacking surface is slightly inclined to facilitate drainage, and pay attention to placing the materials straight to prevent bending and deformation.

6. The stacking height should not exceed 1.2m for manual work, 1.5m for mechanical work, and 2.5m for stack width.

7. There should be a channel between stacks. The inspection channel for ductile iron pipes is generally 0.5m, and the access channel depends on the size of the material and the transportation machinery, generally 1.5-2.0m.

8. The bottom of the stack should be raised. If the warehouse is on a sunny cement floor, the height should be 0.1m; if it is a mud floor, it must be raised by 0.2-0.5m. If it is an open field, the height of the cement floor should be 0.3-0.5m, and the height of the sand-mud surface should be 0.5-0.7m.
