The number one priority in pipeline industry is the public safety. These is because every day, pipelines operate below our feet and many people are not even aware. The priority in ensuring public safety is all aimed at maintaining pipeline integrity. The hydrostatic pipeline testing is one management process that is used to protect such integrity. This process involves 24/7 maintenance and monitoring, and a high-level leak detection and inspection processes.
Hydrostatic testing is the process that requires the pipelines to be filled with a liquid usually water, and then pressurizing it to a higher level that exceeds normal operation pressure. The process enables the pipes to be defect free. This type of test is not limited only to pipelines but it also used in measuring the strength of boilers, gas cylinders, plumbing and fuel tanks.
While performing the test, a measure of pressure tightness is taken through the closing of supply valves, then examining for any loss in pressure. For a simple detection of the leaks, a colored liquid becomes a bit better to use. By taking a measure from the vessel of permanent deformation, one is at a position to measure the containers strength. By this method of testing, vessel durability and safety standards are maintained ultimately. Altogether, fresh vessels are generally originally qualified by means of a hydrostatic test.
For many years, this kind of test has been used to determine and verify pipeline integrity. Through this process, many defects can be detected. Examples of these defects are active corrosion cells, material defects, pipe mechanical properties, localized hard spots and stress corrosion cracking which may lead to failure when hydrogen is present. When correct pressure is used, the test is always important for the non-destructive pipeline evaluation, and judiciously used to attain necessary results.
Generally, pipelines intended for use at a particular maximum pressure necessitate for tests that determine if they are able to withstand internal pressure and for structural soundness before they put to use. For instance, gas pipelines are hydro tested prior to use. A segment of the pipe is filled up with water and then the pressure is propelled into specified value typically above the maximum pressure for operating. This pressure is maintained for a specified duration in-between four to eight hours.
Usually, this testing is normally safe and is an accepted approach for testing pipelines. In case the pipelines fail during the test, there is usually, large water leaks. Although the leakage may cause some flooding, plans are usually put in place together with a repair team.
Before any test is carried out, extensive planning normally takes place in order to minimize any form inconvenience to the locals as well as the customers. However, depending on the weather and gas venting location, you could smell gas. Such a situation is normally safe.
Subsequent to the test, contaminants in the used water is filtered of prior to draining from pipes. The water can be released through a permit to an open field or sewer systems as soon as it is tested and declared clean.
