Liquid Penetrant Inspection

Nondestructive Testing: Liquid (Dye) Penetrant Inspection

An industry standard for decades, liquid penetrant remains one of the most reliable, efficient, and cost-effective methods for detecting surface flaws in non-porous metals. Stork nondestructive testing and liquid penetrant laboratories feature processing lines, which enable our technicians to conduct liquid penetrant testing on everything from small electronic components to large parts up to 15 feet in diameter—and our portable penetrant systems allow us to conduct comprehensive onsite testing.

Types of liquid penetrant inspection services

Stork provides Type II non-fluorescent nondestructive testing services to all of the various commercial and nuclear codes, as well as Type I fluorescent inspection to aerospace, government, nuclear, and after-market applications.
