Liquid Penetrant Inspection for Near-surface Flaws

Liquid penetrant inspection is a reliable, harmless method of finding near-surface flaws in products and parts. Lab Testing performs the inspections with either fluorescent dye or visible penetrants. We offer water-washable and post-emulsifiable fluorescent penetrants in sensitivity levels 2, 3 and 4 to meet your specification or application and use high-quality Magnaflux inspection materials. Since the test pieces are covered in penetrant during the inspection process, it is important that the products have a non-porous surface.

Our liquid penetrant inspection department is equipped to inspect products up to 25 ft. long such as pipe, tubing and barstock. We're equipped with three large penetrant dip tanks, a 25 ft. dwell tank and a large inspection room with three high-intensity black lights.
