Abstract: There presently exists a high level of industry knowledge, corporate standards and supporting documentation regarding the testing and commissioning of pipelines. A welded pipeline, incorporating flanges at each end, and at any valve pits, offers little scope for leakage other than through failure of a weld (or through corrosion/wear on older lines).

Thus, integrity of such lines can be proved by a hydrostatic strength test with such tests being verified by suitable calibrated instruments such as dead weight testers.

At each end of the pipeline is perhaps an AGI, gas terminal or power station, each a complex network of pipes, vessels, flanges, instruments and threaded connections.

On such installations each pipe spool, valve, instrument etc will have undergone a hydrostatic test at source, however upon installation, a large number of field connections/joints are made, each with the potential for atmospheric leakage.

Part 1 of the following paper describes various techniques for testing such field connections as found on natural gas plants and AGIs, discusses the various merits of each technique, and offers conclusions as to the most applicable method.

Part 2 of the paper goes into greater depth regarding nitrogen/helium leak detection and the benefits it offers.
