Nondestructive Testing (NDT)

RNDT provides industrial radiographic testing services in both our laboratory and in the field at customer locations. We have traditional film based and digital computed radiographic testing services. Our custom built mobile darkrooms are easily set up in less than 10 minutes. We have several exposure vaults that allow for very large parts to be examined. We have several X-ray cabinets for small parts such as electronic chips. Also, we provide high volume processing of film with state-of-the-art ecologically friendly automatic processors. Our Level II and Level III radiographers are experienced in many different specialty techniques involving geometrically challenged parts.

Industrial radiography involves the use of penetrating X- or gamma radiation to examine parts and products for flaws that could be detrimental to their intended use. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part onto a film or an electronic device (plate). When the film or plate is processed, a negative-like picture is obtained that shows the internal characteristics of a part. Possible imperfections show up as density changes in the film, in much the same way an x-ray can show broken bones.

Ultrasonic testing uses the transmission of high frequency sound waves into a material to detect imperfections within the material or changes in material properties. The most commonly used ultrasonic testing technique is pulse echo wherein sound is introduced into the test object and reflections (echos) are returned to a receiver from internal imperfections or from geometrical surfaces of the part.

Our Level II and Level III certified UT technicians work to many codes in many industries. From thickness readings on ASTs to performing full length ultrasonic examinations on 40′ long seamless pressure vessels.

Liquid Penetrant testing is probably the most widely used NDT method. The test object or material is first cleaned and then coated with a visible or fluorescent dye solution. After a pre-selected time interval (dwell time), the excess dye is removed from the surface, and then a developer is applied. The developer acts like a blotter and draws penetrant out of imperfections which are open to the surface. With visible dyes, the vivid color contrast between the penetrant and the developer makes the “bleedout” easy to see. With fluorescent dyes, an ultraviolet lamp is used to make the “bleedout” fluoresce brightly, thus allowing the imperfection to be seen readily.

With a wide variety of penetrant materials and a custom made fluorescent penetrant inspection system, we can provide both field and lab, high volume processing of many different parts with both fluorescent and visible penetrants.

Magnetic particle testing is done by inducing a magnetic field in a ferro-magnetic material and dusting the surface with iron particles (either dry or suspended in a liquid). Surface imperfections will allow the magnetic field to leak out of the part, distort the magnetic field and concentrate the iron particles near imperfections, thus indicating their presence.

Magnetic Particle Testing, or Magnaflux as it is sometimes called, uses magnetic leakage fields to detect surface and subsurface cracks and discontinuities.

Our Magnaflux 6000 amp bench units with 8′ head stocks, portable power packs, yokes, prods, black lights and all required accessories provide the foundation for RNDT to provide quality MT visible and fluorescent, wet and dry examinations in both the lab and field.

Probably the oldest and most common method of NDT is visual examination, which has numerous industrial and commercial applications. Examiners follow procedures ranging from simple to very complex, some of which involve comparison of workmanship samples with production parts. Visual techniques are used with all other NDT methods.

By use of many different gauges, micrometers, calipers, rulers, magnifying devices, remote video equipment, and surface conditioning equipment, we provide both lab and field visual inspection services.

Positive Material Identification (PMI) is a nondestructive means of determining the chemical composition of metals. In a global sourcing environment, material can inadvertently be mixed up and cause serious issues while in service. Innov-X Alpha Series

We can quickly and accurately determine the chemical composition of many different metals. We have several Innov-X Alpha Series X-ray fluorescence units and experienced technicians that can provide this service anywhere in the USA.

X-ray fluorescence (XRF) is the emission of characteristic “secondary” (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.

RNDT has NDT professionals that are recognized worldwide as leaders in the field of nondestructive testing. We have several professionals that have been active in nondestructive testing for thirty plus years working in all industries. We can develop a nondestructive testing technique for you on your product. Fill out a request form and we will contact you within 24 hours.

Nondestructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. Because NDT does not permanently alter the article being inspected, it is a highly-valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI),eddy-current testing.
