Preparation Phase Welding inspection & Pressure testing All the new pipe work, including the service pipe work was manufactured and tested at Fairwood Fabrications Ltd workshop. Before leaving the workshop every weld was 100% MPI tested and each pipe section pressure tested with compressed air to one and a half times the maximum working pressure. A quality assurance (QA) file complied throughout the manufacturing process was produced and formed part of the Health and Safety file. 16
Preparation Phase Expansion Joint The only design change from the original crossover design was the inclusion of an expansion bellows. This was to allow for any thermal expansion likely to have taken place when the new crossover at ambient temperature is connected to the working gas system with temperatures around 80° C. 17
