This manual is a comprehensive reference tool in the field of hydrostatic testing of pipelines, primarily those transporting liquid and gas hydrocarbons, but also the general principles applying to water and other types of pipelines.
Hydrostatic testing of pipelines: Zen and the art of the squeeze is intended to comprise a comprehensive reference in the field of hydrostatic testing of pipelines, primarily those transporting liquid and gas hydrocarbons, but also the general principles applying to water and other types of pipelines.
Pressure testing, where hydrostatic is a subset (and testing with air is another), is used to determine that a pipe or pipeline or pressure containing structure is fit for the purpose intended (strength test), and is usually followed by a leak test.
Pressure testing is required by standards internationally but is all-to-often, lightly considered in both the design and construction phases. This book is offered in an attempt to urge a more detailed consideration of the subject
It is generally written around the requirements Australian Standard AS2885.5, whose requirements are typically more stringent than the requirements of other comparable standards.
About the author
Lynndon Harnell graduated from University of Queensland in 1978 with a Degree of Mechanical Engineering. His first experience with hydrostatic testing was in 1980 when employed with The Pipeline Authority on the Young to Wagga Pipeline under the direction of Mr Ken Bilston, himself a figure of authority in the industry and a member of the Standards Committee.
Since then Mr Harnell has worked on a continual basis in the pipeline industry in design, construction, operations, testing and commissioning of pipelines. He has performed numerous hydrostatic tests as a NATA signatory for four NATA laboratories, and is currently a member of the ME 38.5 Standards Sub-Committee for hydrostatic testing of pipelines.
