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 carrying out the test, pressure tightness is normally measured by shutting the supply valve and then checking if there is a pressure loss. For easier detection of the leaks, it would be better if the liquid is colored. By measuring the permanent deformation of the vessel, you are able to measure the strength of the container. Through this test method, safety standards and vessel durability over time can be maintained. At the same time, new vessels are usually initially qualified through the 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.
The contaminated water that is used is usually filtered of after the testing is done, before being released from the pipes. Clean and tested water can be released into an open field or a sewer system once permitted by the relevant authority before it is released.
