Propane pressure should generally be between 100 and 200 psi to guarantee that liquid propane gas remains liquid. Normally, the pressure within a propane tank varies significantly depending on the temperature outside.
What is a propane tank’s maximum psi?
A provincial safety manager is issuing this instruction under section 30 of the Safety Standards Act.
This regulation specifies the conditions that must be satisfied in order for propane storage tanks with a maximum allowed operating pressure (MAWP) of 200 psig to continue to operate (1380 kPa).
Tanks that were produced with an MAWP of 200 psig in compliance with CSA B51 Boiler, Pressure Vessel, and Pressure Piping Code (B51) and / or one of the following codes are included in the scope of this directive:
- Section VIII Division 1 of the ASME Boiler and Pressure Vessel Code, paragraphs U60 or U69 from the 1949 (or earlier) edition; or
- Section VIII Division 1 of the ASME Boiler and Pressure Vessel Code, paragraphs U200 or U201, 1949 (or later) edition
Propane storage tanks with an MAWP of 200 psig are allowed to continue to operate as long as the following conditions are met:
- The following requirements apply to tanks produced in accordance with paragraphs U60 or U69 of the 1949 (or earlier) edition of American Society of Mechanical Engineers (ASME) Code section VIII-1:
- Within the five (5) year period immediately preceding November 1, 2017, the tank must have been inspected by a certified and competent person and verified to be safe for continuing operation.
- According to National Fire Protection Association – 58 – Liquefied Petroleum Gas Code, the tank must be equipped with a pressure relief valve with a maximum set pressure of 250 psig and a minimum relieving capacity (NFPA-58).
- After the date of issuing of this order, the tank may only continue in operation at its existing position and may not be transferred and placed into operation at a new location.
- The following requirements apply to tanks produced in accordance with paragraphs U200 or U201 of ASME Code Section VIII-1, 1949 (or later) edition:
- To increase the MAWP from 200 to 250 psig, the tank must be re-rated in compliance with the NB-23 National Board Inspection Code. Before November 1, 2017, the tank re-rating documentation, including revised calculations, inspection records, and any other needed documents, must be submitted to BCSA for design registration.
- According to NFPA-58, the tank must be equipped with a pressure relief valve with a maximum set pressure of 250 psig and a minimum relieving capacity.
Propane tank owners must comply with the directive’s criteria by November 1, 2017.
Propane tanks that do not meet the directive’s requirements by November 1, 2017 are not allowed for continued operation and must be removed no later than May 1, 2018.
BCSA will begin enforcing regulations in accordance with the directive’s compliance dates. BCSA maintains the right to take urgent action in order to prevent, avoid, or minimize the risk of personal injury or property damage.
Propane Storage Tank – A “Tank” is a type of container designed and built in accordance with CSA B51 for the storage of compressed natural gas or propane.
A propane tank pressurized above 103 kPa (15 psig) and with relief valves set at a pressure greater than 103 kPa is said to be in operation (15 psig)

Is it possible for a 1 pound propane tank to explode?
Propane tanks do not burst into flames. They don’t implode, rupture, or disintegrate on their own. In truth, raising a propane tank to the point of “explosion” is a much more complex and time-consuming procedure than most people believe. Many people believe that a propane tank “explosion” can happen at any moment. This is not the case, and people should be aware that under normal circumstances, a propane tank will not explode or rupture. Explosions, accidents, and propanetank ruptures or breaches are all prevented by safety measures and processes. Human mistake, like any other hazardous material or activity, is a major role in preventing or contributing to any form of mishap, no matter how serious.
Is it safe to replenish propane tanks that hold one pound?
The US Department of Transportation advises the public not to refill DOT 39 cylinders, such as the 1 pound camping cylinders. These containers were not made to resist the stress of being emptied and refilled.
Never refill DOT 39 cylinders, which are 1 pound cylinders used for camping, according to the public. DOT 39 cylinders, regardless of size, are not refillable. There have been Hazmat incidents involving refilled DOT 39 cylinders, including one fatality.
What is the best way to increase the pressure in my propane tank?
Is it possible to increase the gas pressure? No, you won’t be able to raise the pressure. The low pressure regulator is set to 6 ounces, or 10.5 Water Column Inches.
Is it possible for a propane tank to explode in the sun?
Yes, they are capable. Temperatures can quickly soar on a hot summer day. The pressure within the propane tank will rise as the tank heats up. Despite the fact that portable propane tanks include safety relief valves to release pressure, the best place to store a tank is out of direct sunlight. Outdoors, in the shade, and in cool temps is the safest place to store a propane tank.
Is it permissible to keep a propane tank in the garage?
Do you use cylinder-style propane tanks for your grill? If that’s the case, you’re well aware of the many benefits of grilling with propane, including its ease, convenience, and excellent outcomes.
These propane tanks can be used for a variety of purposes around your home in the Seacoast region. Outdoor fireplaces and firepits, pool and spa heaters, patio and deck warmers, insect traps, and portable generators can all be powered by them.
However, there are a few things you should know about storing them safely. We’ve compiled a simple, user-friendly dos and don’ts list.
Dos and Don’ts of propane tank storage
DO NOT expose propane tanks to temperatures over 120 degrees Fahrenheit. It could result in a leak or, even worse, combustion.
DO NOT keep propane tanks in a garage, basement, carport, shed, sunporch, or carport.
DO NOT put propane tanks on their sides, since this might cause liquid and vapor leakage.
DO NOT put propane tanks on wet ground or any other wet surface, since this can cause the tank to rust and pit, rendering it ineffective if not lethal.
When taking propane tanks to be refilled or exchanged, keep them upright and secure.
DO NOT STORE PROPANE TANKS IN CLOSED AUTOMOBILES. That implies you can’t conduct any other errands while getting your propane tank exchanged or refilled.
Make sure you have your gas tank professionally refilled by a licensed propane distributor.
REFILLING OUTDATED TANKS WITH EXPIRED CERTIFICATION IS NOT A GOOD IDEA. It’s against the law to do so. Propane cylinders must be recertified 12 years after their manufacture date, and then every five years thereafter.
How many times can a 1 pound propane cylinder be refilled?
Certification for Propane Containers Disposable 1 pound cylinders, on the other hand, are solely intended for one-time use and cannot be recertified for refilling. If you opt to refill a disposable tank, you are violating the tank’s official certification.
Is it possible to refuel little Coleman propane tanks?
Camping with Coleman propane gas canisters is a great idea. They’re used to power portable propane camping lamps and outdoor cooktops. While these canisters are typically thrown away once they’ve been emptied, they can be refilled with a 20-pound propane tank.
Does the pressure in propane tanks decrease over time?
If you’ve ever lived in the Hudson Valley, you know how frigid the winters can be. In January, the average low temperature in Newburgh is 20 degrees Fahrenheit. It gets a lot colder if we get an Arctic blast from Canada or the Midwest.
When the weather drops below freezing, you may question if the propane inside your aboveground propane tank will freeze or be damaged.
Propane has a freezing point of -44 degrees Fahrenheit. Newburgh has had temperatures as low as -20 degrees Fahrenheit. As a result, there’s no need to worry about your propane freezing.
While it’s rare that your propane will freeze in this climate, it can still be damaged by extreme cold. When it gets chilly, propane contracts. When it’s really cold outside, the volume of propane in your aboveground propane tank shrinks, resulting in a pressure reduction. The issue is that if the pressure in your tank drops too low, the propane within will not be able to reach your gas burner. That means you may be unable to use your propane appliances, such as your furnace or boiler, which can be extremely inconvenient in extreme cold.
That’s why, when Old Man Winter comes knocking, you should be prepared.
Avoid low propane pressure problems
- Keep your propane tank at least 30% full since the more propane you have, the more positive pressure you will have. Check your propane tank gauge and call Depew Energy to plan a propane delivery if extremely cold weather is expected.
- Allowing snow to accumulate on your gas tank is not a good idea. It should be clear so that sunshine can reach your tank and warm it up.
- Reduce the temperature in your home. Your furnace or boiler will run less frequently, allowing your propane tank’s pressure a time to replenish.
