Precautions for Steel Storage and Basic Maintenance Of Materials

Oil Black Seamless Steel Pipe supplier introduces you to the steel storage precautions:

1. Material warehouse requirements

1. Keep the material warehouse clean and drained away from harmful gases or dust. Weeds and all debris should be removed on the site to keep the steel clean.

2. In the warehouse, it should not be stacked with materials that are corrosive to steel, such as acids, alkalis, salts, and cement. Different types of steel should be stacked separately to prevent confusion and contact corrosion.

3. Large sections of steel, rails, steel plates, large-diameter steel pipes, forgings, etc. can be stacked in the open air.

4. Small and medium-sized steel, wire rod, steel bar, medium-caliber steel pipe, steel wire, and wire rope, etc., can be stored in a well-ventilated shed but must be placed on the toe pad.

5. Some small steels, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steels, and high-priced and easily corroded metal products must be put in the warehouse.

6. Please pay attention to the ventilation on sunny days, and close the moisture-proof on rainy days, and often maintain a suitable storage environment.

Second, reasonable stacking, advanced first release

1. The principle of stacking is that under the conditions of stable palletizing and ensuring safety, palletizing according to varieties and specifications, different types of materials should be palletized separately to prevent confusion and mutual corrosion.

2. It is forbidden to store items that have a corrosive effect on steel near the pallet.

3. The bottom of the stack should be high, firm, and flat to prevent the material from being damp or deformed.

4. The same kind of materials is stacked separately according to the order of storage, which is convenient to implement the principle of advanced first.

5. The steel bars stacked in the open air must have wooden pads or strips below, the stacking surface is slightly inclined to facilitate drainage, and pay attention to the placement of the materials straight to prevent bending and deformation.

6. Stacking height, the manual operation does not exceed 1.2m, the mechanical operation does not exceed 1.5m, stack width does not exceed 2.5m.

7. There should be a certain channel between the stack and the stack, the inspection path is generally O. 5m, the access passage depends on the material size and transportation machinery, generally 1.5 ~ 2. Om.

8. The bottom of the stack is high. If the warehouse is the concrete floor of Chaoyang, the height is O. 1m is enough; if it is muddy ground, it needs to be high. 2 ～ 0.5m. If it is an open field, the height of the cement floor is O · 3 ～ O · 5m, and the height of the sand surface is 0.5 ～ O. 7m.

9. Angle steel and channel steel should be stacked in the open air, that is, with the mouth facing down, the I-beam should be placed upright, and the I-groove surface of the steel should not face up to avoid rusting.

Carbon Steel Seamless Line Pipe

3. Keep the warehouse clean and strengthen material maintenance

1. Carbon Steel Seamless Line pipe should pay attention to prevent rain or mixing impurities before entering the warehouse. The materials that have been rained or stained should be cleaned by different methods according to their properties, such as high hardness Available wire brushes, low hardness cloth, cotton, etc.

2. The materials should be checked frequently after entering the warehouse. If there is rust, the rust layer should be removed.

3. After the surface of the Casing Seamless Steel Pipe is cleared, there is no need to apply oil, but for high-quality steel, alloy thin steel plate, thin-walled pipe, alloy steel pipe, etc., both the inner and outer surfaces are required after rust removal. Store with anti-rust oil.

4. The steel with serious corrosion is not suitable for long-term storage after derusting, and should be used as soon as possible.
