What are the different types of blow lamp gas canister? |
||||
| There are five different forms of gas canister available which contain a range of gases. | ||||
Butane gas canister |
||||
 |
Butane is an alkane, which is a type of gas made from hydrogen and carbon. It produces the lowest temperatures of all of the gas canisters, with a maximum of 1350°C (2462°F). These canisters can be used in air temperatures as low as -3°C (26°F).
Butane gas canisters can be used for soft soldering and are available for standard and swivel blow lamps. |

 |
||||
Propane gas canister |
||||
 |
Propane is an alkane, similar to butane. However, it has fewer carbon atoms than butane. It produces a hotter flame, up to 1900°C (3452°F), than butane propane mixed gas canisters (see below), which means it is a better gas source for brazing and soldering large-diameter pipes.
It can be used at temperatures as low as -20°C (-4°F). |
|||
 |
A propane gas canister can be used by all the varieties of blow lamp and comes in either 340g (12oz) or 400g (14.1oz) sizes. | |||
Butane propane mixed gas canister |
||||
 |
Butane propane mixed gas canisters are the most common variety available. They contain a 35% propane and a 65% butane combination which creates more heat than a purely butane canister, with a flame temperature up to 1750°C (3182°F).
Butane propane mixed gas canisters can come in sizes ranging from 170g (6oz) to 350g (12.3oz). |
|||
 |
It can be used by all four varieties of blow lamp at temperatures as low as -15°C (5°F). | |||
Mixed gas canister |
||||
 |
Mixed gas canisters contain a combination of propane, butane, propene and acetone. This combination of gases creates a very hot flame of up to 2100°C (3812°F) which is ideal for brazing.
It can only be used by heavy duty blow lamps and is only available in one size: 210g (7.4oz). |
|||
 |
Mixed gas can be used at temperatures as low as -18°C (-0.4°F). | |||
Propane and methyl acetylene propadiene gas canister |
||||
 |
Propane and methyl acetylene propadiene gas canisters are the hottest commercially available gas canister and produce a flame of up to 2200°C (3992°F).
They can come in sizes ranging from 400g (14oz) to 450g (15.9oz). |
|||
 |
They are used for brazing, welding, and cutting metals. They are only available for use with a heavy duty blow lamp and can be used at temperatures as low as -20°C (-4°F). | |||
