If you're going diving then chances are that you're going to look into buying or renting a scuba diving tank. The proper name for these heavy pieces of equipment is actually a diving tank or even a diving cylinder, but most people just use the phrase scuba tank since this is what they are usually referred to as even though British divers tend to use 'diving cylinder' more than other cultures throughout the world.
Anyone who wants to use a scuba diving tank should first learn how one works, especially if it is your first time to use one. Each diving tank has something called a diving regulator demand valve. When the diver needs air, he or she operates the valve and receives this gas, or high pressure breathing air. Most full tanks contain enough air to last for a week or so without having to be refilled again until fully empty. Various factors, including capacity, quality and other important things, go into choosing which particular tank to buy. Getting a good tank means better safety over your life.
Aluminum or Steel
The primary thing that must be taken in to your thought is the type of material you would want. There are two variations in these tanks which are steel and aluminum, and each one has their own benefits and flaws. Anyway both aluminum and steel are prone to corrosion by the sea water. If you do not put in special care then corrosion may happen in a very short period of time given the conditions the tanks go through. So you need to be highly careful in protecting your tank to always be sure that the corrosion does not happen within a few months. A carefully handled scuba tank will last for many years for any diver.
Any diver has two choices for a diving tank in steel and aluminum, however, the advantage with steel is that it is stronger, more ductile, has less effective cost of construction. The advantage of aluminum over steel is that it weighs less than a steel tank, resulting in the diver having more buoyancy. Nonetheless, they are beneficial in different scenarios; steel tanks work best in deeper waters to due to its weight and aluminum works best in waters that are not that deep.
Know Your Pressure
You will also need to consider the amount of pressure you need your tank to have before you decide which one is right for you. Both aluminum tanks and steel tanks have low and high pressure tanks which are recommended for diving. Numbers like 2640 psi, 3000 psi and 3442 psi are usually the common amounts of pressure seen throughout the diving industry for scuba diving.
Each have Benefits and Drawbacks
High-pressure and low-pressure tanks have their own advantages and disadvantages. Low-pressure tanks are better for technical divers. They also are less likely to fail. On the other hand, they are larger than high-pressure tanks are. The main advantage of high-pressure scuba tanks is their smaller size, which makes them easier to handle. Their main drawback is the increased stress placed on portions of the tank. High pressure can lead to damages being done to the O-ring or other components, as well as ultimate tank failure. It is best to get advice before choosing a particular kind of scuba tank. Divers who have experience with both types can give useful insight into the decision process. The choice between high-pressure and low-pressure is not the only one you will have to make. There are many different aspects of tanks to consider, and each will come into play when you go diving.
