Nondestructive Testing Services

Conductivity Inspection

Conductivity inspection measures the electrical conductivity of a metal part or component. This is an in process test of chemical processing to verify the integrity and consistency of a chemical processing operation.

Hardness Testing

Hardness testing verifies the hardness of the base material, and can be used to validate that previous processes have been performed correctly. All Valence products are guaranteed to meet specified standards.

FPI (Fluorescent or Liquid Penetrant Inspection)

Fluorescent penetrant inspection is a type of dye penetrant inspection where a non-permanent fluorescent dye is applied to a non-porous part to detect cracks and defects that are invisible on sight inspection. This type of inspection is a highly efficient method to testing parts.

Magnetic Particle Inspection

Magnetic particle inspection detects surface and shallow subsurface discontinuities in ferromagnetic materials. This inspection can give immediate data and reveal errors or defects. It will prevent future leaks and other flaws.

Eddy Current Testing

Eddy current inspection uses electromagnetic induction to find and characterize surface and sub-surface defects in conductive materials. It is a highly sensitive form of testing for small surface defects, providing immediate results.

Copper Sulfate Testing

Copper sulfate testing verifies the effectiveness of, or need for passivation on a stainless steel part. This test is proficient in advanced aerospace applications.

Boroscope Inspection

Boroscope inspection allows the internal surfaces of geometrically complex components to be visually inspected for surface finish integrity. The inspection can prevent small issues in materials that potentially lead to huge losses in the long-term.

Valence performs all of these services to the highest degree of care, with approvals for most prime and military specifications. Our products and services significantly enhance safety, long-term use, and consistency in the aerospace industry. View our specs here.
