Spiral steel pipe is a spiral seam steel pipe, which is made of strip coil plate as raw material, often formed by warm extrusion, and welded by automatic double-wire and double-side submerged arc welding process. 

Helical steel pipe stacking principle requirements：

1. spiral steel pipe stacking principle requirements are stable, ensure the safety of the palletizing premise, according to the variety, specifications of the palletizing, different varieties of materials to be palletizing, prevent muddy and mutual erosion;

2. It is forbidden to store items with a corrosive effect on steel around the stacking position of spiral steel pipe;

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

4. Stack the same material according to storage successively;

5. open stacked spiral steel pipe steel, the following must-have wood mat or stone, stack surface slightly inclined, to facilitate drainage, and pay attention to the material placed straight, to prevent bending deformation;

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

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

8. open stacked Angle steel and channel steel should be placed, that is, the mouth down, I-beam should be placed vertically, the steel I groove surface can not face up, so as not to rust water;

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