Join Dye Penetrant Testing Course in Houston to the Learn the Best NDT Procedure
Posted by James Blake on January 19th, 2017
Non-destructive testing (NDT) is a descriptive term used for the examination of materials and components in such a way that allows materials to be examined without changing or destroying their usefulness. NDT or NDE can be used to find and locate surface and subsurface flaws and defects.
NDT is particularly effective because materials are tested in ways that do not alter the integrity or usefulness of the substance being examined. This makes the technique incredibly useful for determining the safety and reliability of products that are currently in use as well as those intended for future use. NDT methods can detect internal and external irregularities and imperfections, determine the structure or composition of materials, and make accurate measurements of the products being tested - without destroying them. NDT plays a crucial role in everyday life and is necessary to assure safety and reliability. Typical examples are found in aircraft, motor vehicles, pipelines, bridges, trains, power stations, refineries, buildings, and oil platforms which are all inspected using NDT.
NDT can be done using one of the various procedures and one such procedure is dye penetrant testing. Due to its ease and flexibility, not only many organizations are adopting it, but more and more people are joining dye penetrant testing course in Houston, TX and other places. Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied low-cost inspection method used to locate surface-breaking defects in all non-porous materials. DPI is a non-destructive method for finding discontinuities that are open to the surface of solid and essentially non-porous materials. Indications of flaws can be found regardless of the size, configuration, internal structure, or chemical composition of the work piece being tested and regardless of the flaw orientation. Liquid penetrant can seep into various types of minute surface openings by capillary action. Because of this, the process is well suited for the detection of all types of surface cracks, laps, porosity, shrinkage areas, lamination, and similar discontinuities in castings, forgings, welds and other product forms. Dye penetrant inspection is used extensively for the testing of wrought and cast products of ferrous and non-ferrous metals, powder metallurgy parts, and ceramics and glass objects.
In practice, the liquid penetrant inspection process is relatively simple. Equipment generally is simpler and less costly than that for the most other NDT methods. When used on ferromagnetic steels, in some instances, the sensitivity of liquid penetrant is better than that of magnetic particle testing.
