What Does Pressure Systems Equipment Include?
There is a legal requirement for thorough examination of pressure vessels and receivers that contain steam, compressed air, and refrigerants. Any pressure vessel containing relevant fluid over 250 bar/litres capacity requires inspection.
Examples of pressure systems and equipment are:
-
Boilers and steam heating systems
-
Pressurised process plant and piping
-
Compressed air systems (fixed and portable)
-
Pressure cookers, autoclaves, and retorts
-
Heat exchangers and refrigeration plant
-
Valves, steam traps, and filters
-
Pipework and hoses
-
Pressure gauges and level indicators
-
Air conditioning plant
You can find a full list of items requiring PSSR thorough examination/inspection on our Equipment Safety Checklist page.
When Are Pressure Vessel Inspections Required?
To establish whether you need a pressure vessel inspection, multiply the vessel operating pressure (in bar units) by the vessel capacity (in Litres) i.e. 10 bar x 50 Litres = 500 bar/litre capacity and therefore is above the 250 bar/litre threshold and requires an inspection with a written scheme of examination.
Owners and users of refrigeration plant containing pressure vessels, with compressor power over 25 kilowatts, also require a written scheme of examination and inspection.
