This test method covers procedures for detecting or locating leaks, where quantitative measure is not practical. The technique is applicable to any test specimen on which a pressure differential can be created across the area to be examined. An example of this technique is the application of leak-test solutions to pressurized gas-line joints. It is most useful on piping systems, pressure vessels, storage tanks. Three types of boxes (test frames) are applied by CORROCONT Ltd. that can be fitted to the proper type of weld: butt weld, overlap weld, corner fillet weld.
This testing method covers procedures for detecting or locating leaks, where quantitative measurement is not practical. Where it is necessary, permanent records can be obtained by photography or digital imaging and storage. The main drawback of visual inspection is that the surface to be inspected must be relatively clean and accessible to either the naked eye or to an optical aid. Typically, visual inspection lacks the sensitivity of other surface NDT methods. CORROCONT Ltd. has corrosion engineers and specialized NDT professionals who perform visual inspection according to the most important international standards like API 653 and EEMUA 159.
