Pressure testing a compressed air system

Preparing for the test

Before carrying out a pressure test a risk assessment must be carried out. This is often submitted to the client alongside a method statement. The risk assessment should consider the hazards involved in over-pressurising the system. At this time permit-to-work documents, any training, and health and safety criteria should be discussed and met with the client. The pipework system will be mapped out and components specified. In some cases certain parts of a system may require inspection before a test is carried out.

Pressure test

The system or part of the system will be isolated and a stab in point identified. Pressure relief valves will be changed for higher pressure models and a high pressure mobile compressor and regulator will be installed at the stab in point. The system will be checked and we will start to increase the system pressure by 0.5 bar increments. Once the pressure is at 1.5 times standard operating pressure we will valve off the compressor and take readings from our testing gauge system. Readings will be taken at 10 minutes intervals. Once the test is complete we will exhaust excess pressure in the system through a safe diffuser, replace safety valves and recommision system. Results will be analysed and a test certificate issued.
