An Overview of Dye Penetrant Inspection
Non-destructive testing methods are cost-effective and will enable you to save a lot of time, money, and effort in getting the results you need to make informed decisions about your project. One of these is the dye penetrant inspection (DPI) or dye penetrant test, which is specifically used to identify surface breaking flaws. Sometimes referred to as, ‘liquid penetrant inspection’ (LPI), this method can assist in detecting cracks, seams, laps, porosity, and other kinds of surface breaking voids. This inspection method can be used on non-porous materials both ferrous and non-ferrous, which includes materials such as ceramics, metals, and plastics. Dye Penetrant inspection is often used to find defects in welded joints, forgings, and castings. It is applicable to multiple industries, including aerospace, petrochemical, and power generation. Provided you have the correct equipment, and follow approved and consistent procedures, inspections can be conducted on-site or in remote areas
