Precautions for the preservation of seamless steel tubes:

1. The site or warehouse for storing steel, whether it is seamless steel pipe or other straight seam steel pipe, should be selected at the midpoint of clean and clean, poor drainage, away from the occurrence of harmless gas or dust. Weeds and all kinds of debris should be cleared on the site, and the steel should be clean;

2. Do not stack materials that are corrosive to steel, such as acid, alkali, salt or cement, in the warehouse. Different types of steel should be identified and stacked to avoid mixing and avoid contact corrosion;

3. Large-scale steel, rail, insult steel plate, large-diameter steel pipe, forgings, etc. can be stacked in the open air;

4. Small and medium-sized steel, wire rod, steel, medium-diameter steel pipe, steel wire and wire rope, etc., can be stored in a well-ventilated shed, but must be placed on the underside;

5. Some small steel, thin steel, steel, silicon steel, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steel products, and high-priced, corrosive metal products can be stored in the warehouse;

6. The warehouse should be selected according to astronomical conditions. Ordinary blockade warehouses are generally used, that is, there are walls with walls, doors and windows close to each other, and a ventilated installation warehouse;

7. The warehouse requires sunny attention to ventilation, rainy days to pay attention to closed moisture, often adhere to a suitable storage environment.


Seamless tube washing is especially important, here are the notes:

1. When the seamless steel pipe is washed, it needs to be carried out in the flowing clear water tank. This can avoid secondary pollution. When washing, the seamless steel pipe needs to be fully immersed in water. At this time, the sling should be relaxed, up and down. It can be four times.

2. When washing, it is necessary to clean the water in the steel pipe to avoid water corrosion and oxidation of the steel pipe. Therefore, it is necessary to process the solvent as soon as possible.

3. It should be noted that it is not possible to cross the pickling tank to avoid accidents, slipping or falling into the acid tank and being corroded by residual hydrochloric acid.

4. The need for iron salt content standards must be controlled within a certain range, can not appear excessive conditions, otherwise it may damage the seamless steel pipe.
