Guide Scrap SCUBA Tanks

Long-time divers frequently end outdoor adventures white water rafting up with old SCUBA cylinders that can no longer be used for various reasons. Perhaps diving is a long-forgotten hobby or the tanks may have failed inspection. Often, these tanks end up gathering dust in a garage because there are no clear instructions on how to dispose of them.


Visual Inspection

Most local dive shops offer annual visual inspections to their customers. These inspections, called Visual Inspection Program (VIP) ensure that each SCUBA cylinder is in proper condition to be filled. During a VIP, a qualified technician checks for rust inside the tank or for the telltale signs of a crack that's beginning to form.

Tanks that show evidence of internal rust are sent out to be "tumbled." The tank is filled about halfway with a cleaning solution and tumbling media. Tumbling media consists of small, rough particles that slough rust off of the inside of the tank. Most tanks can be salvaged through this process, unless the damage has become too severe.

Hydrostatic Testing

Hydrostatic testing is a more complex test that must be performed every five years on SCUBA cylinders. During the test, the tank is filled with water and submerged in a pressurized, water-filled chamber. That way, if the tank ruptures, it will be less dangerous because it is filled with water instead of highly compressed gas.

A tank that fails this inspection seldom will be salvaged. Once it has ruptured, the tank is no longer useful. At this point, it's time to seek out an area to scrap the tank.
