TRADITIONAL NDE SERVICES
While NDE Methods have evolved, and we specialize in offering more advanced forms of inspection, we also understand there may be a need for conventional methods. Our team has over 50 years experience with Traditional NDE methods.
Ultrasonic testing is the most common form of NDT. UT uses high frequency sound waves that travel through material. If the sound wave encounters a subsurface volumetric discontinuity, a reflected signal is produced and can be measured to characterize the indication. UT is useful for both metallic and composite parts, making it a very important disciplines to find cracks, voids, de-lamination, and other indications. The simplest form of UT is thickness measurement where the thickness of material can be measured.
MAGNETIC PARTICLE INSPECTION
Magnetic particle Inspection (MPI) is a non-destructive testing process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials. The process puts a magnetic field into the part through direct magnetization. When the electric current is passed through the test object and a magnetic field is formed in the material. The magnetic lines of force are perpendicular to the direction of the electric current, which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).
LIQUID PENETRANT INSPECTION
Liquid penetrant inspection (LPI) is a non-destructive test method process for detecting open to surface discontinuities in Ferrous and Non-Ferrous Materials. The process does not harm the samples or parts being inspected. Liquid Penetrant testing is very effective in detecting porosity, cracks, fractures, and other flaws that are open to the surface of the test piece. As a result, it is often used on machined parts, welds, castings, and forgings.
Visual Inspection (VT) is used to identify surface imperfections utilizing the human eye. These inspections can be performed utilizing direct site of the component or remote visual aids such as mirror, magnifying glass or video probe. Common tools such as measuring tapes/rulers, digital vernier’s and weld profile gauges are used to verify weld profile tolerances and discontinuity size.
EDDY CURRENT (TUBULAR)
Eddy current testing uses electromagnetic induction to identify defects in tubing. A probe is inserted into the tube and pushed through the entire length of the tube. Eddy currents are generated by the electromagnetic coils in the probe and monitored simultaneously by measuring probe electrical impedance. The information revealed by the probe will detail the tube defects. The scanning data will be recorded by the software and kept us as a backup for future reference.
Radiography (RT) is a method of inspecting materials for seeing hidden flaws by using the ability of short X-rays, gamma rays, and neutrons to penetrate various materials. It's a major element of non-destructive testing. Radiography is used to inspect castings, concrete, and a wide variety of welds, such as those in gas and water pipelines, storage tanks and structural elements. It is a full volumetric inspection that can identify flaws that may not be otherwise visible through visual inspection or other non-destructive testing methods.
