The rule of thumb when determining nitrogen gas bottle sizes is to buy the biggest bottle you can handle to limit the amount of refills you will need. There is now greater availability on the market for customers to choose the nitrogen gas bottle sizes they require, compared to when suppliers only offered the traditional D and G sizes.

However, this increase in variety has made it confusing for some customers who do not know which nitrogen gas bottle sizes they require to ensure they can complete their jobs.

Below we outline some things to consider to help you determine whether our C, D, E or G size nitrogen cylinders are best for you.

How much volume do you require for your nitrogen gas bottle?

The smallest nitrogen cylinder we stock here at Rent Free Gas is C, followed by D, E, and G as the largest. In comparison, a D cylinder has a volume of 1.7m3 and a weight of 20kg, whereas a G cylinder has a volume of 8.7m3 and a weight of 80kg.

So if you can work out your flow mate required, or if you know the volume & pressure required of the tyre you would like to fill, the volumes of each cylinder above should help you.

Shelf-life of nitrogen

Since nitrogen is a non-reactive gas mixture and is usually filled in steel cylinders, your nitrogen gas bottle should, generally, have a shelf life of at least three years. This should be taken into consideration when deciding how much volume you actually require and which nitrogen gas bottle sizes you need.

Do you need to move the cylinders?

This is an important safety consideration as large nitrogen gas bottle sizes are difficult to handle and transport, weighing up to 80kg. If you need to travel from location to location to complete welding works, then it is important you have nitrogen gas bottle sizes that can be easily moved and will fit into each workspace.
