Hydrostatic Pipeline Testing
Hydrostatic testing evaluates the performance of fluid pressure vessels such as cylinders, tubes or pipelines. Detecting leaks, manufacturing flaws and device safety are other important reasons for conducting pipeline hydrostatic testing.

Pipeline operators conduct pressure tests in order to determine the reliability of a pipeline construction. Testing on pipelines occur before they are placed into service and during their period of operation. Hydrostatic tests are carried out after pressure tests have been conducted.
Hydrostatic Testing
-
After pressure tests are performed, operators initiate hydrostatic testing on pipelines. Unlike pressure tests, which circulate a medium (gas or water) throughout the pipes to detect problems, hydrostatic testing focuses on a certain area of the pipeline in order to test the pressure within the pipes. Pressure that is used in hydrostatic testing is carried out at a higher rate than normal operating conditions.

Hydrostatic tests take place at high pressure ranges in order to evaluate the amount of pressure that a pipe can handle before it expands and cracks. This is important for when operations require a higher than normal volume of liquid to pass through the pipeline. Visual and physical examinations of the pipeline occur after testing in order to see if the pipeline was damaged during testing.
