Conventional NDE

Conventional NDE

Conventional NDE (Non-Destructive Evaluation) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used. IIA Laboratory Services offers a wide variety of NDE testing at our numerous facilities nationwide.

Coating Thickness Testing

A coating thickness gauge provides information on the expected life of the substrate, the product's fitness for purpose, its appearance, while also ensuring compliance with a host of international codes and standards.


Conventional Radiography (RT)

Conventional Radiography using gamma sources is a prevalent method of non-destructive testing within numerous industries including Oil & Gas because of its proven accuracy, cost effectiveness, high level of portability, and extreme diversity.


Dye Penetrant (PT)

A widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). PT is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.


Hardness Testing

Hardness testing is performed in the field with a small hand-held device and is used to gauge the strength of the metal. This is useful when determining the correct welding electrode to use during structural repair.


Magnetic Flux Leakage (MFL)

Used to find areas of metal loss due to corrosion or erosion, MFL is most common in inspection of pipelines, tank floors and heat exchanger tubes.


Magnetic Particle (MT)

A non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part to facilitate flaw detection.


Pipeline Crawler (X-Ray)

IIA's X-Ray Pipeline Crawler Systems are designed for flaw detection inspection of circumferential butt welds on everything from gathering lines to cross country pipelines with diameters generally between 6 to 60 inches. The speed and safety of our service ensures timely results and minimal restriction to work areas.


Remote Visual Inspection (RVI)

Observe, identify and document the internal condition of hazardous environment-rated equipment.


Ultrasonic Thickness Testing (UTT)

A volumetric non-destructive testing method that uses sound waves to propagate through an object.


Vacuum Box Testing (VBT)

VBT is used to test the integrity of the seal between two plates, usually on a lap weld joint. Vacuum box testing is commonly used in tank inspections for roof and floor repairs. Special box shapes can be made to test corners and curved surfaces.
