Outline of the different gas bottle sizes in Australia

Dec 27, 2018 Posted by Walter Ingles

In Australia compressed gases are stored in three different cylinders types, each with their own standard sizes denoted by a letter code. In this blog we outline the different gas bottle types and sizes (capacity/dimensions) as specified by Australian Standard AS4332-2004 -  The storage and handling of gases in cylinders.

REMEMBER: compressed gases are classified as Dangerous Goods as well as Hazardous Chemicals. If you are getting confused trying to manage your safety obligations why not download our free eBook Gas Cylinder Storage: Compliance and Safety Requirements.

REMEMBER: All measurements are approximates only as sizes and weights will vary depending on the gas type, volume, and fill pressure.

 

LPG Cylinders

LPG Cylinders come in a range of sizes with their own letter codes. From fuelling gas BBQs to powering forklifts, you are probably familiar already with many of these cylinder sizes. Here are a few examples:

  • Sizes N and P — used for home BBQs and camping equipment
  • Sizes Q/T and R  — used to power forklift trucks;
  • Size S — commonly used for heating domestic homes and small business plus premises operating commercial gas appliances; and
  • 90kg tanks — permanently installed and filled onsite at residential homes or businesses operating commercial gas appliances.
