See full version: Things to know about propane tank pressure
Contact your local propane distributor for assistance. Additionally, some people think that pressure can be used to determine how much propane is in a tank. That is incorrect. Pressure readings do not translate into volume readings.
As an example, for any volume of propane inside of a propane tank when at 80 degrees Fahrenheit, the pressure is about 128 psi. If the temperature is lowered to 50 degrees Fahrenheit, the pressure is about 78 psi. If the temperature is lowered further to zero degrees Fahrenheit, then propane pressure will reduce to 24 psi. more
Therefore, using propane appliances and propane tanks in colder climates can present issues that require professional assistance such as selecting the propane tank size. Additionally the wide variation in possible pressure changes is one reason why using a two stage pressure regulator is important.

What is the operating pressure for propane?
Likewise, can a propane tank be used for compressed air? Use propane tank for air compressor. If it's rated for the pressure you will exert with a compressed air system, then I can't see why not, as the tank doesn't care if it's liquid propane or compressed air inside. On the other hand, if you can't identify the pressure range for the tank, don't take a chance. more
LPG gas cylinder-bottle pressure all depends on the temperature. At 100°F, a 100 lb propane tank has 172 PSIG of pressure. Similarly, a 45kg gas bottle has 1183kPa at 38°C.

Disposable non-reusable (non-refillable) cylinders For 20 pound (5 gallons) Liquefied Propane cylinder (type 4BA) the pressure will vary by temperature. At 70 degrees Fahrenheit, the pressure should be 145 PSI. here
A common operating pressure for liquid petroleum or LP gas appliance is 10" - 11" of water column (WC) or re-stating this in equivalent measures, that's 27.4 millibars or 2491 - 2739 Pascals or Pa, or about 0.36 - 0.40 psi or about 5.78 to 6.36 ounces of pressure per square inch. here
Found primarily on older tanks, external relief valves operate in the same manner as an internal relief valve with the spring mechanism being outside the propane tank itself. Relief valves on multvalves are always fitted with external safety relief valves. Older tanks with an external relief valve installed on the container are generally replaced with internal pressure relief valves, provided they are connected to a dedicated tank opening specifically designed for the placement of the relief valve. here
Because the safety relief valve performs such a vital role in the protection of the propane tank, it should be maintained and repaired by licensed propane professionals only. Do not ever look into a relief valve or stand over it. [links]
Relief valves are held in the closed position by the force of a powerful spring. As long as the pressure inside the tank is less than that of the spring, the valve will remain closed. If tank pressure rises to that of the spring, the valve will open resulting in a hissing sound outside the tank. If the pressure in the tank rises significantly higher than that of the spring, the valve will fully open. When the valve fully opens, it initially makes a loud pop followed by a blast of released propane gas. Once the pressure is released and the tank pressure falls below that of the spring, the valve closes. more
The safety relief valve is one of the most important and vital valves on any LP Gas container. All propane tanks and cylinders are required by law to be fitted with pressure relief devices designed to relieve excess pressure. The function of a safety relief valve is to keep a propane tank from rupturing in the unlikely event of excessive pressure buildup. Propane tank relief valves are also known as pop off valves, pressure venting valves or relief valves.
Most propane tanks in residential and commercial service have internal safety relief valves. The reason for an internal valve as opposed to an external pressure relief valve is it presents less of an obstruction when moving the tank. Internal relief valves are generally placed near the end of the propane tank on above ground containers.
The typical high pressure regulator is set around 10 PSI. Low Pressure LP is rated in inches of water column (in WC). The typical rating for low pressure LP is around 10.5 - 11 inches WC. here
Similarly, it is asked, what is the PSI of a low pressure propane regulator? [links]
One may also ask, what is the difference between a high pressure and low pressure propane regulator? Differences Between Low- & High-Pressure Propane Burners. Low-pressure propane burners regulate gas intake to about 6 ounces per square inch, whereas high-pressure burners regulate gas intake to between 1 and 60 pounds per square inch. The intake difference determines the burners' application: outdoor or indoor. more
The propane barbecue can use a high-pressure propane delivery system, which requires a high-pressure regulator. This can vary from between 10 and 60 psi (the pressure measurement). Or, you can have a low-pressure delivery system (for propane barbecues up to 50,000 btu).
Are all gas grill regulators the same?
