Scuba Tanks Inspection / Tests and Service

Dive Right Co LTD offers Inspections, tests and servicing for SCUBA Cylinders. Local law specify the following:

• Scuba Tanks should be Visually Inspected every 12months
• Scuba Tanks should be Hydrostatically Tested every 5 Years
• Scuba Tanks should be Specially Cleaned for o2 uses.

If you own and operate your own Compressors we also assist in compressor maintenance and spare parts for Bauer and Coltri-sub

As tank owners, we get a visual inspection every 12 months (usually when we take the tank in for a fill and a shop employee notices that the tank is out of inspection). It may be something that we rarely think about, but it’s an important part of being a safe diver. We are going to break down the visual inspection process

Technician will remove the valve Smell for anything that may be “off”; the smell of dead sea life could mean water intrusion, the smell of hydrocarbons or a burnt odor could indicate a previous fill from a compressor with failing piston rings or a bad filter. inspector will also check the tank valve, to determine if it needs service or a cleaning Tech will take a closer look at the inside of the tank, with a long, flexible LED light. The tech is looking primarily for iron oxide in steel tanks and aluminum oxide in aluminum tanks pitting or any other inner issues.

Hydrostatic Testing Scuba Tanks is required by law, and for good reason! Scuba Tanks need to be Hydro Tested every 5 years to ensure the integrity of the Scuba Cylinder. Hydro Testing will confirm the expansion of your Scuba Tank is within safe limits to continue use.

The purpose of a hydrostatic test is to locate any flaws that would put the diver in danger, much like the visual inspection. Here the technician is looking for leaks in the tank. The hydrostatic test takes it a step further from the visual inspection and physically tests the limits of the cylinder by use of water and pressurization. The tank is filled with water, and submerged into a sealed chamber. A burette, which is a type of measuring cylinder, is connected to the sealed chamber to record the water displaced during pressurization. The tank is then pressurized to 5/3 of its normal pressure The amount the tank has stretched to after deflation is called permanent expansion. To determine whether the tank is a pass or a fail, the permanent expansion is subtracted from the total expansion, which provides the technician with the elastic expansion. If the value of the elastic expansion exceeds the limits set for your cylinder, it will be condemned, and marked as such or with Xs over the DOT specifications. If the tank passes the hydrostatic testing, it will be stamped with the date and ID number for the shop that carried out the testing. See you in another 5 years!

Why is it necessary to clean scuba tanks?

Oxygen Service To remove contaminants that can become the fuel for an oxygen-fed fire.
Contaminated Cylinder Clean Removes contamination after a tanks leak or bad fill
