LPG stands for Liquefied Petroleum Gas. The term is widely used to describe both Propane and Butane.

The term “liquefied gas” may seem a contradiction in terms yet liquidity is the unique character of LPG that makes it such a popular and widely used fuel. At normal temperature and pressure, LPG is gaseous. It changes to a liquid when subjected to modest pressure or cooling which means it can be easily stored in bulk tanks or portable cylinders so providing energy wherever it is needed. In liquid form, the tank pressure is about twice the pressure in a normal truck tyre, which means it is very safe when properly handled.

LPG is a by-product of two large energy industries: the processing of natural gas liquids and the refining of crude oil. It used to be burned off and wasted but after its value as a versatile low carbon fuel was recognised it quickly became established globally as a widely available exceptional energy source that is perfect for a wide range of applications from providing heat in homes and industry to powering the Olympic flame.

Propane and Butane are chemically quite similar but Propane turns to a gas at a lower temperature suiting outdoor storage and is primarily used for central heating, cooking, as a transport fuel and for numerous commercial applications.

Butane is used mainly in cylinders for portable applications in mobile heaters in the home, and for leisure activities such as boats, caravans and barbecues. On its own, it can also be used as a propellant, refrigerant or to fuel torches.

Often, Propane and Butane will be mixed to deliver the best energy yields and properties.

Regulators do not have an unlimited life. Failure may result in a fire or explosion if the gas accumulates and an ignition source is present. All regulators should have their date of manufacture stamped on or marked on them and should be replaced in accordance with the manufacturers instructions. If the instructions have been lost or do not give such information the regulator should be replaced not more than 10 years after manufacture. If in doubt please fell free to contact us.

If you have a cylinder you no longer need, the simplest route is to return it the company whose name is on the cylinder. You should also have a paper contract with the details of who owns the cylinder. The gas cylinder can be returned directly to them or to one of their approved stockists or agents.

Tanks needs to be tested by a ‘competent person’ to meet obligations under the Pressure Systems Safety Regulations. Often they are inspected on each fill and tested at 10 and 20 years but the duty is that they are checked in accordance with the owner’s (usually the LPG supplier) ‘Written Scheme’. Such schemes have to meet legal duties but can vary widely. If you are concerned please feel free to contact us.
