What You Should Know About Scuba Tanks

Picture
A scuba tank is an essential piece of equipment for anyone who plans to on a dive. This tank can either be rented or purchased, depending on whatever suits you best at the time. In truth, the more appropriate name for a scuba tank is the "diving tank" or "diving cylinder," the latter of which is the popular usage with British divers. However, the most common phrase worldwide is known as the "scuba tank".

Anyone who wants to use a scuba tank should first learn how one works, especially if it is your first time to use one. Each scuba 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.

Two Choices

Firstly, you might want to consider the type of material that is necessary for your diving needs or wants. Scuba diving tanks are available in either aluminum or steel, and each has their own unique benefits as well as their own faults. The drawback to both, unfortunately, is that salt water will definitely cause these materials to corrode over time. However, this does not have to happen and can be avoided if proper upkeep and maintenance is performed regularly on your scuba tank. If completely taken care of, the tank will endure the corrosive effects of the salt water and will last sufficiently long enough for a number of years instead of just a few useless months.

Any diver has two choices for diver 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.

Pressure Plays an Important Role

You should think about what pressure you want your diving tank to contain because that is a major factor to take into account before getting a scuba tank. Both aluminum and steel tanks come in either low- or high-pressure options. The most common scuba diving tank pressures used are 2640 pounds per square inch, 3000 pounds per square inch, and 3442 pounds per square inch.

High and Low Pressure Tanks

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 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 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 scuba tanks to consider, and each will come into play when you go diving.
