How Does A Hydrostatic Tester Work?

Hydrostatic testers are used for pipeline testing to assess the strength and quality of pressure vessels. Hydrostatic testers are used for pipes, pipelines and vessels to expose any defects (such as leaks) that might impair the performance of the pressure vessel. 

Energy content (high pressure water and/or air) of the vessels has the potential to do great damage. Safety standards in Australia require the integrity of a pipeline must be determined by a hydrotest before use to prevent any complications and hazards as well as to ensure underground piping is free of leaks.

Depending on the vessel you’re testing, you’ll need to follow certain procedure codes. For example, leak testing codes will differ from field pressure testing. Read more on the guidelines of hydrotesting at The Australian Pipelines and Gas Association.
