Scuba Tanks

SCUBA (Self-Contained Underwater Breathing Apparatus) tanks are designed for dependability as an underwater life support apparatus and engineered for reliability. Dive gear must be maintained routinely to ensure that your diving experiences are without incident.

Routine testing of your SCUBA tank is required to ensure that the tank is qualified as "compliant" with the Department of Transportation and able to be filled with compressed breathing air in accordance with the Code of Federal Regulations.  Hydrostatic Testing of your tank is mandatory every 5 years by a licensed DOT Hydrostatic Testing Facility.

Cylinder Testing Services, LLC has been hydrostatically testing scuba tanks for over three decades. As a leader in the testing industry, we test scuba diving cylinders to verify that the tank can hold the air pressure it was designed for.

A visual inspection of the tank is performed in our facility to check for thread imperfections including metal loss, galling, corrosion, cracking and abuse in accordance with the Compressed Gas Association. A mandatory Eddy Current Test is conducted on all aluminum cylinders manufactured with 6351-T6 aluminum alloy to check for sustained load cracking of the neck and shoulder of the cylinder.  A hydrostatic test of the tank is then performed by our personnel to  "qualify" the cylinder as "able to ensure the integrity of the manufacturer's pressurization requirements".

Once this testing is completed, our RIN (Re-qualifier's Identification Number) is stamped into the cylinder and this "qualification" is generally good for five years from the test date.
