Basic inspection item
Appearance integrity: check whether the barrel body is sunken, deformed or seriously corroded (focusing on edges and welds).
Sealing test: let it stand for 24 hours after water injection to observe whether it leaks (special attention should be paid to the tightness of the lid and the body of the closed barrel)
Residue detection: illuminate the inner wall with a strong flashlight to confirm that there is no chemical residue or odor (food/medical use needs to be strictly cleaned).
2. Material and process verification
Status of galvanized layer: the zinc layer is even and free from peeling (it can be tested by magnet, and the galvanized barrel should be non-magnetic).
Welding quality: the weld is straight without cracks, and there is no hollow sound when knocking.
Inspection of accessories: valves, handles and other accessories are firm and not loose.
