Question: How long do steel scuba tanks last?

How long do scuba tanks last years?

What is a scuba tank’s lifespan? Both aluminum and steel scuba tanks can last for 10-15 years (steel tanks for even longer), assuming they are properly maintained. If not, then corrosion, rust, or physical damage can compromise a tank and force you to replace it much sooner than expected.

What is the life expectancy of all steel and aluminum cylinders?

Cylinders constructed from aluminum or steel must be tested every 5 years. All composite SCBA cylinders have a maximum service life of 15 years, provided they are hydrostatically re-tested on a regular basis in accordance with DOT regulations.

Are old scuba tanks good for anything?

Old tanks are not necessarily unusable as scuba equipment. If the tank’s hydrostatic test date is passed, send the tank in for testing. Steel tanks have a very long life and steel tanks from the 1950s can still be found in perfect working condition.

Do scuba tanks go bad?

We often take for granted that our cylinders are safe, and that dive staff has tested and properly cared for them. But if a cylinder “goes bad,” it can have life-changing (or even life-ending) consequences for the diver or whomever is filling it. Scuba cylinders leave the factory tested to strict engineering standards.

How much does it cost to certify a scuba tank?

Federal Law requires a new hydrostatic test every five years for most SCUBA tanks. AHS will provide this service for $55 per tank and it includes the test, a visual inspection, and an air fill. Hydro with a Nitrox fill is $62. Please note that additional charges may apply if the valve requires cleaning or rebuild.

How do I know if my scuba tank is aluminum or steel?

Aluminum is softer than steel. Aluminum tanks must have thicker walls than steel tanks to hold air at a comparable pressure. Because aluminum is softer than steel, it scratches and dents more easily. Steel tanks may rust in the presence of moisture.

What do you do with old scuba tanks?

Diving tanks should be returned to the manufacturer, via dive centres or re-fillers. If you are unsure if a cylinder can be returned, it is advisable to contact the manufacture.

How do I dispose of old scuba tanks?

You can bypass your local dive shop and go straight to the scrap metal dealer. It’s important that they are empty and the valves removed so that it’s obvious the cylinders pose no danger. Scrap metal dealers typically pay by the pound. A garage full of unwanted or unusable tanks could be turned into cash swiftly.

What can you do with old scuba gear?

If your gear doesn’t sell, however, it will, depending on the individual store’s policy, either go to a recycler or the trash can. Consider donating your gear to an organization that uses divers, like your local aquarium.
