We have many years experience and are qualified to service most common models of equipment on site. Most manufacturers recommend annual servicing which involves a strip, clean and rebuild to ensure safe and reliable performance from your equipment. Servicing can take a few days especially in the lead up to summer holidays so drop your equipment off early to ensure it will be ready on time. As with all servicing the cost varies depending on what parts are required. Our staff can provide estimates prior to the repair starting. It is a legal requirement to have your Scuba Cylinder either hydrostatically pressure tested or visually inspected every year. To check if it is in date find the most recent date stamped on the top of the cylinder. If the date is more than 12 months old, check if there is a plastic tag with a date around the valve.
Of all our equipment, we often overlook our scuba cylinders the most. But when scuba cylinders have problems, there are often disastrous consequences. These aluminum or steel vessels retain our breathing gas at incredibly high pressures. Modern regulators then convert that high-pressure gas to intermediate and then ambient pressure, meaning that, whatever your depth, you should receive a smooth flow of breathing gas.
If the date is more than 24 months old then the cylinder needs a hydrostatic test. This costs $50 including a fill. It is a good idea to make a note of the date in the.
Scuba Cylinders by Conrad H. Air means life, and the container that carries your air therefore means life, which means it has to be absolutely fail-safe. That’s why scuba cylinders–which are also referred to as “tanks” or “bottles”–must not only be of high quality, but they are also subject to periodic inspection and testing. Each tank has a series of codes on it and each has inspection and testing stickers.
If those are out of date, no responsible, reputable dive shop will refill the tank. As you can see, diving certification agencies take no chances. Imagine if gas stations would refuse to let you fill up your tank if the inspection sticker on your car is expired; that’s how strict diving regulations are.
The Scuba Cylinder
Checking scuba tanks for hydro dates is critical in the scuba diving industry. It is important for tanks to be inspected and safe to ensure your safety while diving. Each tank has a series of codes on it and each has inspection and testing stickers. If those are out of date, no responsible, reputable dive shop will refill the tank. Visual inspections are required at least once per year to check for cuts, dents, stress lines, bulges, plating condition, a current hydrostatic test date, and signs of general abuse outside, and pits, corrosion, coating defects, neck cracks, and thread integrity inside.
If all is well, the inspectors puts the tank back together and applies a new sticker.

Five Reasons to Date a Scuba Diver
The cleanliness and physical condition of dive cylinders can directly effect the safety of divers. The recent rapid increase dive tourism activities in esatern Indonesia has caused a sharp increase in the need for supporting services. Recognising this need, PT EON Engineering has recently opened a hydro test station to international standard at our workshop in Sorong.
EON prioritises safety and high quality of service in all aspects of the work carried out. To avoid dangerous the build up of aluminium oxide we use factory reccomended anti corrosion and anti galvanic compounds when reassembling the dive cylinder and valve. External Cleaning Using a system that removes all labels and corrosion to allow full visual inspection.

Although a cylinder may seem like a dumb hunk of metal, it does serious work. Filled to capacity, a typical cylinder carrying 80 standard cubic feet of air — enough to fill a phone booth — compressed to a pressure of 3, psi carries a total energy roughly equivalent to an automobile traveling at jet airliner speeds. More important than that, our scuba cylinder carries our most precious cargo of breathing gas to sustain us for the duration of our dive. Without a doubt, a high-pressure scuba cylinder is something worthy of respect.
To ensure our continuing safety below and above the waves, scuba cylinders demand at least a modicum of attention to selection, use, care and maintenance. While cylinders are marketed under a number of brand names, only a handful of manufacturers produce scuba cylinders in the United States, including Catalina, Faber, Luxfer, and Pressed Steel Tank Co. Creating a scuba cylinder is no minor feat, and it requires a great deal of pressure.
Dive tank permanent expiration?
Whether you call them dive tanks or scuba cylinders or a variation of those terms, the container that holds your air while you dive is a critical part of your equipment. It is also the least understood, most abused and possibly the least used if you purchase one. Many new divers will get their full dive kit and feel it is not complete without their own dive cylinders.
At the time of purchase, you should consider any hydro test date less than 24 months old to be acceptably recent. For popular size tanks with hydro test dates older.
Scuba Cylinders are high pressure vessels and as such should be handled carefully. They should be washed after use and the valves serviced every twelve months the same as your other valuable gear. In Australia all scuba cylinders are required to be hydrostatically tested every twelve months. This is carried out in accordance with Australian Standard The cylinder is then stamped around the neck area indicating the month and year it was tested along with the test station number.
Aluminum cylinders manufactured from aluminum are required to have an ultrasonic or eddy current neck test every two years to inspect for neck cracks that may have developed over time relating to that grade of aluminum. This is indicated with E stamped as part of the test stamp. It is sometimes called a “Visual Plus” test after the instrument used to conduct the test. Aluminium T6 alloy cylinders will not be tested.
Servicing & Cylinder Testing
When the cylinder and valve are discussed as a single unit, SCUBA tank or dive tank is the term used by nearly all divers.

How many years does a scuba tank last? The cylinder holds your air, so it is natural to want to verify its integrity. We will also learn the possible lifespans of scuba cylinders. Want to know how long a scuba tank will last for a dive? I have witnessed aluminum tanks that have successfully passed hydrostatic tests times. This means the tank is 10 to 15 years old.
The manufacturer conducts the initial hydrostatic test. Subsequently, tanks need to pass these tests every 5 years. Certain parts of the world require more frequent hydrostatic testing. While wrong, many dive shops agree that a properly cared for aluminum tank has a service life of about 20 years. In reality, aluminum tanks by engineering can withstand the stress of refills or hydrostatic tests.
For many Florida divers, it is easy to find excuses to postpone the responsibilities of diving. Just like your regulator, BC and computer, your scuba cylinder requires an annual checkup, too. As a full service center, Force-E can make sure that your gear stays in tip-top condition, and receives the care and attention it requires. Each VIP is valid for a year from the date of its last inspection. Before using any scuba tank, check the VIP sticker to ensure it is up to date.

Out of all your scuba diving equipment, your scuba cylinder is the unsung hero of it all. We have a tendency to focus on the quality and maintenance of the wetsuits, BCDs and regulators of wherever we go diving, but not on the most important feature of your scuba equipment, and your lifeline. Scuba cylinders are filled with filtered, compressed air. The air is taken through the air intake of the compressor and passes through a filtration system, where particles and moisture are filtered out of it.
However, even with the proper filtration systems, scuba cylinders still need to be inspected once in a while to ensure that they are in proper working order. The two inspection requirements are the visual inspection and hydrostatic test. Scuba cylinders should be visually inspected once a year by a qualified visual cylinder inspector.

Your tank may have a rubber or plastic boot, which allows the tank to stand where appropriate and creates some protection if it bumps into things. Check underneath the boot periodically for corrosion. To check for internal rust and corrosion, you need to have a professional visually inspect the inside at least once a year. To do this, the inspector drains the tank slowly and removes the valve.
Using a special inspection light, the inspector checks for corrosion, cracks, debris and other possible damage. This service must only be performed by a trained professional at a qualified service center – do not empty the tank yourself. Once the tank passes the visual inspection, the inspector usually puts a sticker with the test date on the cylinder they’re not used in all areas.
