Authorised Examiners (Pressure Vessel)

The types of pressure vessels that the Authorised Examiners are allowed to inspect are listed in the table below.

Definitions:

• Air Receiver (AR) - a container of air under pressure, which includes blasting pots, compressor air tanks and headers.
• Steam Boiler (BR) - a closed vessel in which steam is generated at a pressure greater than atmospheric pressure which includes autoclaves, steam generating heat exchangers, sterilisers, vulcanisers, economisers and superheaters. (up to 1000 sq.m heating surface)
• Steam Receiver (SR)- any vessel or apparatus which contains steam under pressure which includes autoclaves, blow down tanks, deaerators, headers, heat exchangers, sterilisers and vulcanisers.
• Refrigerant Plant Pressure Receiver (PR) - a container of refrigerant under pressure.

Heating Surface is defined as the total surface of all plate and tubes exposed to heat on one side and in contact with water on the other. It is measured on either the water or fire side, depending on which side has a greater heating surface (excluding the heating surface of any economiser and superheater connected to the boiler).
