Liquid penetrant inspection (LPI), 或染料渗透检查, 可靠吗?, 非常高效。, and cost-effective method for detecting surface flaws of welds, 铸件, and other components that cannot be destroyed. LPI or dye penetrant is a portable surface inspection method, allowing our 从事专家 to conduct comprehensive onsite evaluation.
What is 液体渗透检查 Utilized For?
Liquid penetrant inspection is a valuable tool for evaluating non-ferromagnetic and 非金属材料. In addition to utilizing dye in checking for defects and cracks, it can also be used to determine other surface characteristics, 比如孔隙度.
The Dye Penetrant 检查 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), 部分干燥. 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. 根据结果, an inspector then provides a report with the type, number and size of defects on a component.
