1. Choose a suitable site and warehouse

1) The venue or warehouse where seamless steel pipes are kept should be selected in a clean and well-drained place, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed from the site to keep the seamless steel pipe clean.

2) They must not be stacked together with acid, alkali, salt, cement and other materials that are corrosive to steel in the warehouse. Different types of seamless steel pipes should be stacked separately to prevent confusion and contact corrosion.

3) Large-diameter seamless steel pipes can be stacked in the open air.

4) Medium-diameter seamless steel pipes can be stored in a well-ventilated material shed, but they must be covered with a tarpaulin.

5) Small-diameter or thin-walled seamless steel pipes, various cold-rolled, cold-drawn and high-priced, easily corroded seamless pipes can be stored in the warehouse.

6) The warehouse should be selected based on geographical conditions. Generally, ordinary closed warehouses are used, that is, warehouses with walls on the roof, tight doors and windows, and ventilation devices.

7) The warehouse is required to be ventilated on sunny days, closed to prevent moisture on rainy days, and a suitable storage environment must be maintained at all times.

2. Reasonable stacking and first-in-first-out

1) The principle requirement for stacking seamless steel pipes is to stack them according to materials and specifications under the conditions of stable stacking and ensuring safety. Seamless steel pipes of different materials should be stacked separately to prevent confusion and mutual corrosion.

2) It is prohibited to store items that are corrosive to seamless pipes near the stacking position.

3) The bottom of the stack should be elevated, solid, and flat to prevent the pipes from getting damp or deformed.

4) Materials of the same kind are stacked separately according to the order in which they are put into storage, so as to facilitate the implementation of the first-come-first-served principle.

5) Large-diameter seamless steel pipes stacked in the open air must have wooden pads or strips of stone underneath, and the stacking surface should be slightly tilted to facilitate drainage. Pay attention to placing them straight to prevent bending and deformation.

6) The stacking height shall not exceed 1.2m for manual operation, 1.5m for mechanical operation, and the stack width shall not exceed 2.5m.

7) There should be a certain channel between stacks, and the inspection channel is generally O. 5m. The access channel depends on the size of the seamless pipe and the transportation equipment, 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, the height must be 0.2~0.5m. If it is an open-air venue, the cement floor should be padded with a height of 0.3 to 0.5m, and the sand and mud surface should be padded with a height of 0.5 to 0.7m.
