RNDT, Inc.

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 speciality techniques involving geometrically challenged parts.

Industrial radiography involves the use of penetrating X-ray 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 of 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.

RNDT’s Magnetic Particle Testing equipment consists of Magnaflux 6000 amp bench units with 8′ headstocks, portable power packs, yokes, prods, black lights and all required accessories to provide the foundation for RNDT to provide quality MT visible and fluorescent, wet and dry examinations in both the lab and field.

Magnetic particle testing is done by inducing a magnetic field in a ferromagnetic 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.

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.

Using Positive Material Identification, RNDT Inc. can quickly and accurately determine the chemical composition of many different metals. RNDT has the newest technology when it comes to X-ray fluorescence units.

RNDT technicians are highly trained and certified. We are prepared to provide Positive Material Identification services anywhere in the United States.

Ultrasonic Testing uses the transmission of high-frequency sound waves into a material to detect imperfections within the material or changes in material properties. RNDT’s 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.

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 geometrical surfaces of the part.

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, micrometres, callipers, rulers, magnifying devices, remote video equipment, and surface conditioning equipment, we provide both lab and field visual inspection services.
