liquefied petroleum gas

Liquefied Petroleum Gas is composed predominantly of propane, butane or propylene or a mixture of these gases.
When compressed moderately at normal temperature it becomes a liquid. When gas is withdrawn from a cylinder the pressure drops and the liquid reverts to gas.

The expansion ratio of gas from liquid is 270 : 1 which means that you will get 270 liters of gas for every liter of liquid LPG. Therefore it is a significant advantage to transport it in liquid form.

LPG vapor is 1.5 times as heavy as air and when released with little velocity it drops to the ground.

Because LPG has no natural odour, a distinctive odorant is added so that it will be noticeable should a leak occur.

Liquefied Petroleum Gas Safety

Some people are concerned about their safety when they put a LPG cylinder in their car.

As can be seen in the graph, at IIGL Industries the factory test pressure is at least three (3) times higher than the normal operating pressure.

On top of that is a big safety margin, nearly three (3) times the factory test pressure.

Our cylinders are manufactured from high-strength BHP steels designed specifically for the purpose. This guarantees a cylinder of maximum strength, safety and durability.
