Overview to Pressure Vessel Design and Certifications

Pressure vessels are closed containers designed to hold gases or liquids at a pressure substantially different from the ambient pressure. They come in many different shapes and sizes, but they all have one thing in common: the ability to hold pressure.

The design and construction of pressure vessels are regulated by many national and international standards. In Australia, the Workplace Health and Safety Regulations 2008 (PVSR) regulate the design, manufacture and operation of pressure vessels and Competition and Consumer Act 2010 ensure product safety standards to be met when supplying goods to the Australian market.

To ensure your pressure vessel meets all the relevant safety standards, you will need to engage the services of an industrial engineering consultant. We are a team of highly experienced pressure vessel design consultants who can help you with all aspects of certification for your pressure vessel project. From initial concepts and feasibility studies to final pressure vessel certification Australia, we can help you get your project off the ground and ensure it meets all the relevant safety standards.

The Australian pressure vessel regulations are governed under a comprehensively researched set of site-protecting guidelines that ensure the safety of the occupants, equipment and the surrounding area. The standards cover the design, manufacture and operation of pressure vessels, as well as repair and alteration.

Australia's Pressure Vessel Requirements:

According to AS 1210 Standards, it protects life and property against the risks associated with using pressure vessels. The standard covers the design, manufacture and testing of pressure vessels up to 500L volume and 1000 kPa maximum allowable working pressure. Moreover, AS 4343 Standards, it covers pressure vessel design, manufacture and testing for use in the petroleum and natural gas industries. This involves boiler and pressure equipment containers.

Except for Western Australia and Victoria, all the Australian states have the same registration requirements.

A pressure vessel needs to be registered in the following circumstances:

  • If the design of the pressure vessel is not in accordance with an Australian Standard, and
  • If the pressure vessel has a maximum allowable working pressure (MAWP) greater than 500 kPa, or
  • If the volume of the pressure vessel is greater than 500 L.

A Designer is a person who designs pressure vessels in accordance with an Australian Standard. A Verifier is a person who checks and certifies that the pressure vessel has been designed, constructed and pressure-tested in accordance with the standard.

YES, all pressure vessels have to be designed to AS1210. AS 4343 regulations are followed for classifying the pressure vessels. Low risk pressure vessels have lesser requirements and so cost much less for design engineering when compared to a high risk pressure vessel. The risk hence the class of the pressure vessel is to be determined by a suitably competent and qualified engineer. 

Yes, if the vessel is to be used in the petroleum or natural gas industries.

Yes, the registration of a pressure vessel design is recognised by all other states in Australia.

A pressure vessel is a container designed to hold liquids or gases at a pressure different from the atmosphere. Pressure vessels can be found in a variety of settings, including industrial and domestic.

Imported pressure vessels must comply with the Australian Standard in order to be used in the country. The importer and retailer are liable for any accidents that may occur with the pressure vessels.
