The use propane gas tanks

Propane tanks are used for storing propane which in turn can be used for things such as home heating, hot water, dryers, fireplaces, generators, and pool heaters. The more common uses of propane includes.

1. Residential Application: Since propane is not heavy and it burns clean and leaves little residue, it is a good choice of heat production. Hot water heaters, cold weather water heater, space heaters, pool heating, backyard grills, 

2. Refrigeration: This one seems ironic to the first, but one of the industrial uses of propane is as a refrigerant. A cooling element in several equipment.

3. Metal Melting: Now we jump again to the other side of the spectrum. Propane burns at 1980°C and therefore is hot enough to fuel fires that melt several metallic elements. This property is also the primary reason why propane is the first go to fuel in soldering.

4. Equipment powering: Have you ever heard of a filling station being referred to as a gas station ? The “gas” being sold is always propane. Propane is heavy enough to contain enough biochemical energy, yet light enough to easily transport large volumes. This make propane an alternative fuel for light machinery. Lawnmowers, forklifts, backup generators, mobile industrial smelters, tumble dryers, and countless machinery uses propane as essential fuel.

5. Commercial Application: These tanks can be up to a foot in diameter. Dry cleaning, crop drying, pilot lights, and many more commercial propane applications exist.

How To Choose The Right Size Propane Tank

Propane is usually stored in reinforced canisters, the dimensions of the canisters make them adequately a tank. 

Small, portable propane cylinders are called DOT propane cylinders, are used for grills, water heaters, and propane fireplaces. They can be 20-pound propane tank (9 kilograms) to 100-pound propane tank (45 kilograms) and they comfortably contain 5 gallons to 25 gallons of propane respectively. The 20lbs tank is the most popular tank size and it’s better know by its nickname “patio” because of its use for patio heaters. As a general rule, a medium-sized grill on high heat will use approximately two pounds of fuel per meal. Going by this rule, a 20lb propane tank will provide 18-20 hours of cooking time on a medium grill.

Large propane tanks are called ASME tanks. They are not portable and their installment is typically hands-on. They are aboveground propane tanks. Larger tanks can be used to heat home and power home appliances such as stoves and water heaters. Popular sizes among large tanks include the 420lbs tank and the 500-pound gallon tank. These tanks can respectively hold 100 gallons and 400 gallons of propane with comfort. Large stationary propane tanks like those used to heat homes are slightly more difficult to choose. A smaller home requires less propane than a larger home, however, if your home is heavily propane based; then the highest average propane consumption are always around 3.75 gallons per hour.

Larger propane tanks above the ASME are underground tanks. The underground tanks include the 500-gallon propane tank and the 1,000-gallon propane tank.

In order to understand things properly, we must know that 1 liter of propane weighs 0.51 kilograms. Meanwhile, 1 gallon of propane weighs 4.11 pounds (2.21 kilograms). The quantity of propane that you need will decide the tank size that you choose. The dimensions of propane tanks are always measured in centimeters and they are always a measure of height by diameter. If you see any tank that you desire to know its dimensions, just follow the steps below.

How To Measure A Propane Tank

You will need a long flexible measuring tape.

1. Stretch the tape from the base of the tank to the top of the tank. Ignore the handles and measure only the part of the tank that actually contains Propane. This is the height of the tank.

2. Wrap the measuring tape around the tank and note down the two numbers where the tape overlaps.

3. Subtract the lower number from the higher number. Eg. If the two numbers are 34 and 49, then 49 – 34 = 15. This is the circumference of tank.

4. Divide the circumference by 3.142 and you will now have a number known as the diameter. Eg. If the circumference is 15, then 15 ÷ 3.142 = 4.77 . This is the diameter of the tank.

The dimensions of the tank is height by diameter (Eg. 12 × 4.77). Sometimes you might have to round the numbers to whole numbers. Also, if the tank is long sideways and is on its side, then just replace the “height” by “length”.
