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 often does a scuba tank need to be hydro tested?
When to Schedule Hydro-Testing for SCUBA Tanks
The DOT requires hydrostatic tests for SCUBA tanks every five years. If you’re not sure when the last test was performed, check the outside of the cylinder. There, you’ll find the year of manufacture, which is your first hint.
How much does it cost to certify a scuba tank?
Hydrostatic Test Scuba Certification for $25 per tank. Hydro Test your Scuba Tank in 1-2 days so you can get back in the water.
How much are used scuba tanks worth?
Scrap metal value of scuba tanks:
A standard aluminum 80 cu/ft tank weighs about 31 lbs empty. At current rates, scrap aluminum is worth about $0.75 per lb. So the current minimum value of an aluminum scuba tank (without the tank valve) is around $23. A standard steel 80 cu/ft tank weighs about 35 lbs empty.
How long does a hydrostatic test last?
DOT-3AA gas cylinders must be tested every 5 years and have an unlimited life. (Unless stamped with a star (*) in which case the cylinder meets certain specifications and can have a 10-year hydrostatic test life).
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.
How long do scuba tanks last?
But how long a scuba tank lasts also directly depends on the depth at which it’s used. Based on personal experience, an average open water certified diver using a standard aluminum 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 minutes before surfacing with a safe reserve of air.
What is better steel or aluminum scuba tanks?
Because steel is stronger and more ductile than aluminum, construction of a tank requires less steel than aluminum. This usually means that for an equal gas capacity, a steel tank will have a total weight less than an aluminum tank yet have better buoyancy characteristics.
How do I know if my scuba tank is good?
The permanent markings usually indicate the manufacturer, material used in the construction of the cylinder, the service pressure, cylinder serial number, size and the date of the cylinder’s most recent hydrostatic test. The hydro date determines if the tank is safe to fill and use.
What size scuba tank should I buy?
Most recreational divers find a common aluminum 80 to 100-cubic-foot tank is sufficient for their needs. An aluminum 63 cft may be a better fit for a younger and shorter diver while still providing enough gas for their needs. Larger divers tend to have greater gas consumption rates in direct proportion to their size.
Are old scuba tanks good for anything?
Be Certain That the Tank Is Unusable
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.
How do I dispose of old scuba tanks?
Turn old diving tanks into cash
Even if your tank isn’t usable for diving, you may be able to remove and sell the valves, or sell the entire tank for scrap metal. When in doubt, bring it to a local dive shop, where the staff may know how to reuse it.
How often do you have to inspect scuba tanks?
A. NORMAL SERVICE. The visual inspection of every Luxfer scuba cylinder should take place at least once every twelve months, or at any opportune time under twelve months15. Some scuba cylinders need more frequent visual inspection, as indicated below.
Can a hydrostatic test cause damage?
However, hydrostatic testing has been used by the underslab plumbing industry since the 1970s. So how, if the tests themselves cause damage, are they still being used to test anyone’s sewer pipes? The short answer. Because these tests do not cause damage.
What is the difference between Hydrotest and hydrostatic test?
A hydrostatic test is performed by using water as the test medium, whereas a pneumatic test uses air, nitrogen, or any non-flammable and non- toxic gas. At SLAC pressure tests must be hydrostatic unless pneumatic tests can be justified. … Hydrostatic is the preferred method of pressure test at SLAC.
Is a hydrostatic test mandatory?
NO. A hydrostatic test is not mandatory in the inspection of a property. Can a licensed inspector perform a hydrostatic test?
