Stacking principle of spiral steel pipe.

1. The principle requirements of spiral steel pipe stacking are to stack according to varieties and specifications on the premise of stable palletizing and ensuring safety. Different kinds of materials should be stacked separately to prevent confusion and mutual erosion;

2. It is prohibited to store items with corrosive effect on steel around the spiral steel pipe stack;

3. The bottom of spiral steel pipe stack should be high, strong and smooth to prevent the material from moisture or deformation;

4. Stacking the same materials according to the warehousing sequence;

5. The spiral steel pipe section stacked in the open air must have wood pad or strip stone below, the crib surface is slightly inclined to facilitate drainage, and pay attention to the material placed flat and straight to prevent bending and deformation;

6, spiral steel pipe stacking height, manual work is not more than 1.2m, mechanical work is not more than 1.5m, stack width is not more than 2.5m;

7. There should be a certain channel between the stack and the stack. The inspection channel is generally 0.5m, and the access channel depends on the size of the material and the transportation machinery, which is generally 1.5-2.0m;

8, the open-air stacking of Angle steel and channel steel should be placed, that is, the mouth down, I-steel should be placed vertically, the surface of the steel I slot can not face up, so as to avoid water rust;

9, pile bottom pad high, if the warehouse is sunny cement floor, pad height is 0.1m; If the ground is mud, it must be 0.2 ~ 0.5m high. If it is an open field, the cement floor cushion height is 0.3 ~ 0.5m, and the sand and mud surface cushion height is 0.5 ~ 0.7m.
