Pressure vessels - or air receivers - are an integral part of a compressed air system. Most compressed air users will have at least two pressure vessels within their compressed air system; the external air receiver and the internal air receiver - like an oil separator - which can be found within, for example, a screw compressor.
Pressure vessels - or air receivers - are an integral part of a compressed air system.
If improperly installed, used or maintained air receivers can be potentially very dangerous and can lead to catastrophic outcomes such as; fatalities, serious injuries and damage to property. As a result, the governing Australian Standard AS 4343 requires that pressure vessels with a hazard level of A, B, C or D must have their designs registered with the relevant state or territory OHS regulatory body. The design of the pressure vessel must also be verified by an independent design verifying body as part of the registration process, to confirm that the design complies with AS 1210 and/or the original design code.
Australian standards and regulations also requires that pressure vessels with a hazard level of A, B, C & D must be plant registered before it can be used, with the relevant state or territory OHS regulatory body. The responsibility to register the plant design lies with the importer of the pressure vessel into Australia, and the registration of the items of plant lies with the owner or operator of the pressure vessel. Depending on the state or territory, the owner/operator may also be required to periodically renew the registration as well as inform the OHS regulatory body of any changes in ownership, control or relocation of fixed plant.
In accordance with the Australian Standard AS 3788, depending on the size, design pressure and hazard level, an air compressor pressure vessel should be inspected externally every 2 years and internally every 4 years by a competent person.
