How Often Should I Inspect My Dive Cylinder?

2025-07-16

How often should a china diving tank be inspected? This question is of concern to many diving enthusiasts. Generally speaking, diving cylinders should be visually inspected once a year and hydrostatically tested every five years. Visual inspection is to check whether the bottle has any external injuries such as cracks, corrosion, and collision damage, while hydrostatic testing is to test whether the bottle can still safely withstand pressure by filling it with high-pressure water. If your china diving tank is often used for diving, soaked in seawater for a long time, or has been dropped or hit, it is recommended to shorten the inspection cycle of your diving tank depending on the situation, so that it is safe and reliable every time you go into the water.


In fact, many people think that as long as the appearance of the china diving tank is not damaged, it can continue to be used, but "looking fine" does not mean that there are no hidden dangers. Before each dive, it is recommended to conduct a simple self-inspection, such as checking whether the bottle has obvious bumps, scratches or rust, whether the bottle mouth is clean, whether the threads are complete, and whether the air valve rotates smoothly. If there are bulges, deep depressions or corrosion marks on the surface of the bottle, it must be suspended and sent to a professional organization for inspection.
