Factors limiting pickling of stainless steel elbows

The factors that limit the pickling of stainless steel elbows are as follows:

1. Liquids in areas such as decks, walls, dead corners, and the back of escalators are prone to leakage.

2. All deep well pumps, valves, tank washing machines, and other liquid cargo systems on the entire ship must be debugged and ready for use.

3. Large containers should be prepared for the discharge of waste acid and wastewater, but they should be neutralized and discharged as soon as possible to avoid corrosion.

4. If the pickling solution stays in the tank for too long, it will react and cause corrosion of stainless steel, so it is necessary to prepare a large amount of clean water at all times.

5. If the interval between acid pickling is too long, the composition of the pickling solution will decrease with the reaction, and the impurities in the solution will increase. Therefore, it is necessary to replenish the solution at any time.
