Proc. ASME. IPC2012, Volume 1: Upstream Pipelines; Project Management; Design and Construction; Environment; Facilities Integrity Management; Operations and Maintenance; Pipeline Automation and Measurement, 89-95, September 24–28, 2012
Publisher: American Society of Mechanical Engineers
Paper No: IPC2012-90068
... The main purpose of pre-service leak test is to prove the tightness of the pipeline system. It plays an important role to guarantee the safety operating of pipeline. However, the duration of leak test is different in different countries. If the duration of tightness test is longer, the tightness...

Proc. ASME. IPC2008, 2008 7th International Pipeline Conference, Volume 1, 17-23, September 29–October 3, 2008
Publisher: American Society of Mechanical Engineers
Paper No: IPC2008-64034
... of hydrostatic leak test for gas pipeline is developed for the first time in the paper. The influences of temperature variation, elastic deformation of the pipe and a certain amount of residual air filled within the pipe are synthetically considered in the model. The results indicate that the duration is longer...
