液体渗透检查(LPI)

Liquid penetrant inspection (LPI), or dye penetrant inspection, is a reliable, efficient, and cost-effective method for detecting surface flaws of welds, castings, and other components that cannot be destroyed. LPI is a portable surface inspection method, allowing our Engaged Experts to conduct comprehensive onsite penetrant inspection.

Liquid penetrant inspection is a valuable tool for evaluating non-ferromagnetic and非金属材料yabo娱乐vip. In addition to checking for defects and cracks, it can also be used to determine other surface characteristics, such as porosity.

The penetrant inspection process

Parts must go through a pre-cleaning process (etch, alkaline or solvent-cleaning) before the liquid penetrant is applied. After allowing proper dwell time, excess penetrant is removed from the surface (but not from any possible defects), and the part is dried. Then a developing powder is applied; this developer pulls up the dye that has seeped into cracks or pores, resulting in visible marks or indications that identify surface flaws. Based on the results, an inspector then provides a report with the type, number and size of defects on a component.
