Pay attention to corrosion in the dead corners of metals
Thread Content
Dead corners are areas where liquids do not flow well. Through improved design, the hazards of dead corners can generally be eliminated or reduced. The outlet of the container should be located at the lowest point of the liquid, and the part where the liquid can be stored should have an open drain hole. The hazard of dead corners is that, after the container is emptied, the solution accumulated in these areas continues to corrode the container, and corrosive impurities may also deposit there. During normal operation, a concentration cell can be generated because the solution remains stationary in the dead zones. Equipment exposed to the atmosphere must not have pits where rainwater and dust can accumulate. After the container is emptied, check for any water accumulation or impurities; if present, they should be removed.
The risk of corrosion in dead corners within metal containers should be eliminated or reduced through improved design. Ensure that the container outlet is at the lowest point, and provide an openable drain hole for cleaning. After use, check and clean away any accumulated water and debris to prevent long-term corrosion and deposit buildup. At the same time, ensure that equipment exposed to the atmosphere has no water accumulation or dust pockets. .
