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 as a process entails filling up a pipeline with some liquid normally water, then pressurizing the liquid to high levels beyond the usual pressure of operation. This process guarantees that the pipes are free of defect. These manner of tests are not just limited for use in pipelines but also applied in testing the strength and for leaks in fuel tanks, gas cylinders, boilers and plumbing lines.
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.
This type of test has been used for many years to verify and determine pipeline integrity. Through this test process, various flaws can be detected. Some of these flaws are such as material defects, active corrosion cells, stress corrosion cracking as well as actual pipe mechanical properties and localized hard spots which could lead to failure if hydrogen is present. The test is usually important for a nondestructive pipeline evaluation when correct test pressure is used and judiciously utilized to get the 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.
Normally, the test is always safe and it is generally accepted for testing pipelines. If the pipelines fail when being tested, usually there are large water leaks. Plans are always put in place as well as a repair team in case of the leakage. This is because such leakage can cause flooding.
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.
