Information on Pipe Pressure Testing

by:Wingoil     2020-07-03
Pressure testing is a test that is carried out at any under construction site after the installation of the pipes before we put them into the use. This is done to evaluate the certain limits of pipelines in terms of reliability, maximum capacity, leaks, joint fittings and pressure. Without testing the installed pipelines one cannot ensure if pipes meet the standard installation requirements. While non-technically basic purpose of developing the system for pipelines is to ensure the safety of labor working on the construction site and outline the safety practices that must be carried out while testing pipes. The main responsibility of pressure testing lies on two personal, plumbing foreman and project engineer. They perform the hydrostatic test to find out leakages or damages in the pipelines. The information received from the test helps construction personnel to maintain the safety standards and keep the pipelines in good working condition. This information is documented and signed by the assigned personal. The system use two methods: hydrostatic pressure testing and pneumatic pressure. These test methods use the quick couplings and air compressors as the testing equipments. Hydrostatic: This method uses clean, fresh city water and after testing done on the compressed gas pipes water is removed and dry the pipes with blowing dry, oil free air or nitrogen through pipes. Pneumatic: This type of testing is done with dry oil free air or nitrogen on the piping system. Once you have finished testing the pipelines, a report will be given to the owner of the site that pipes have passed all pressure tests before covering them by walls or ceilings. Repair leaks during the tests and keep testing the failed pipes until you get the perfect result. Keep a graphical set of testing. Also stamp the information of tester on the piles including serial number, manufacturer and manufacturing date, REE (Rejection Elastic Expansion) and maximum expansion specified by the manufacturer for safety. While testing the pipelines, the physical security of the testers is also a big concern; all workers involved with the test should wear eye and hearing personal protection equipment (PPE) and mark off the area as dangerous. Extra care should be taken when the tests are being done in a city or high traffic area. Want more information on Pressure testing equipment?
