Non Destructive Testing


Non-destructive testing (NDT) covers a wide group of techniques used to evaluate the properties of a material, part, product, weld, or system without materially affecting the integrity of the unit being inspected or investigated under the test procedure. The techniques can also be utilized to detect, characterize, or measure the presence of damage mechanisms (e.g. corrosion or cracks). Many NDT techniques are capable of locating defects and determining the features of the defects such as size, shape, and orientation. The purpose of NDT is to inspect a component in a safe, reliable, and cost-effective manner without causing damage to the equipment or shutting down plant operations. This contrasts with destructive testing where the part being tested is damaged or destroyed during the inspection process and cannot be used again. The non-destructive testing services we offer are designed to comply with a wide variety of industry standards, most specifications, as well as unique customer requirements.

NDT can be performed during or after manufacture, or even on equipment that is in service.

In manufacturing, NDT inspections determine if parts are fit for a desired function. In other words, parts are inspected to ensure they will last a certain amount of time or cycles before failure. During operation, NDT inspections can be used to assess the current damage state of equipment, monitor damage mechanisms, and make informed decisions for remaining equipment life evaluations such as risk-based inspection (RBI) and fitness for service inspections (FFS).

NDT Inspection Solutions offer NDT methods such as Ultrasonic Inspection, Magnetic Particle Inspection, Liquid Penetrant Testing, Radiographic Testing, (interpretation only for now), Remote Visual Inspections
