How does the spiral steel pipe be stored?

1. The principle of the spiral steel pipe stacking is that under the precondition of stable stacker and security, the stacking of the varieties and specifications should be made, and the materials of different varieties should be stacked separately to prevent muddy and mutual erosion.

　　2. It is prohibited to store articles that have eroded steel around the stacks of spiral steel pipes.

　　3. ASTM A36 Welded Spiral Steel Pipe stacking bottom should be high, strong and smooth to prevent material from damp or deformation.

　　4. the same materials are stacked separately in storage.

　　5. the spiral steel pipe steel stacked in the open air, the underneath must have wooden pads or stones, the stacking surface is slightly inclined to benefit the drainage, and the material is placed straight to prevent the bending deformation.

　　6. Spiral steel pipe stacking height, manual work of not more than 1.2m, mechanical homework of not more than 1.5m, stacking width not more than 2.5m;

　　7. There should be a certain passage between the stack and the stack. The inspection passage is generally 0.5m, and the passage is generally 1.5-2.0m depending on the size of the material and the transport machinery.

　　8. Angle steel and channel steel should be laid down in the open air, i.e. mouth down, I-beam should be placed upright, I-groove surface of steel can not be up, in order to avoid water rust;

　　9. If the storehouse is high, if the storehouse is a sunny cement floor, it can be 0.1M high. If it is mud, it must be 0.2 to 0.5m high. If it is an open space, the cement floor mat will be 0.3 ~ 0.5m and the sand mat will be 0.5 to 0.7m.
