Overview

RNDT, Inc. is an ISO-17025 accredited commercial nondestructive testing laboratory located in Johnstown, Pennsylvania, that specializes in multiple nondestructive testing applications.

We currently service clients throughout the USA and Canada both at their locations and ours.

In 2002, we doubled the size of our Johnstown laboratory and updated our equipment with some of the newest and most advanced technology available.

Our competitive rates, technical expertise and experience have satisfied clients for over 25 years.  We have learned that the closer we work with our customers, the more knowledgeable they become about how we operate and the value that is afforded by allowing experienced professionals to handle their NDT-related needs.

Products & Services
Industrial Radiography

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.

Magnetic Particle Testing

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

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.
