Pressure Testing

Lloyds British International are the no.1 providers of Pressure Testing across the Middle East and Africa

Pressure Testing Services

The Pressure Systems Safety Regulations 2000 (PSSR) require pressure systems to be inspected in accordance with a Written Scheme of Examination. Lloyds British International can provide you with full compliance, by means of thorough examinations together with Written Scheme of Examination documentation.

Pressure vessel regulations apply to owners and users of relevant fluids, including steam, gases under pressure and any fluid kept artificially under pressure and which becomes a gas when released to the atmosphere.

There is a legal requirement for the thorough examination of pressure vessels and receivers that contain steam, compressed air and refrigerants. Any pressure vessel containing compressed gas over 250 bar/litres capacity requires inspection.

Lloyds British International have the most up to date technology and equipment for Pressure testing matched with some of the most qualified personnel in the Pressure System Testing space.

The purpose of the pressure system testing is to investigate the various limits of the pipeline which will test areas such as the reliability, maximum capacity, leaks, joint fittings and pressure. … When pressure testing, the amount of pressure put onto the vessel is always considerably more than the normal operating pressure.

1. The first step of a pressure test is to ensure that all welding is finished properly and has been accepted by the NDT examination  per the project Inspection and test plan.

2. Making sure the inner part of the vessel is clean and free of remaining slag or other elements that may effect the outcome of the pressure test. We would also make sure  that the external surface of the pressure system is dry for the correct execution of the visual inspection during the vessel pressure testing.

3. The next step is our engineer will check the pressure gauges’ calibration tag and certificate and the range of the lower limit and upper limit of the gauges. It needs to be between 1.5 and 4 of the pressure test value for the pressure testing to continue

4. Controlling testing equipment such as the test pump and housing for soundness and tightness.

5. Making sure the test temperature will not violate the following values:

Min. Test temperature= MDMT + 30°F

Max. Test temperature = 120°F

We do this to ensure that the risk of a brittle fracture during the pressure test is minimised.

6. Making sure which reinforcement pads are already soap tested.

7. Controlling the testing water quality and using corrosion inhibitor if it is necessary or when the pressure vessel metal is sensitive material

8. Checking of vents. It is required to be placed at high points of the vessel in a position where it is possible to purge air pockets while the vessel is filling.
