Radiographic Testing (RT) and Inspection Services

Radiographic inspection methods

Our industry-leading radiographic testing and inspection capabilities include a range of traditional and more advanced digital methods of radiographic inspection:

Conventional Radiography

Element’s radiographic inspection staff are certified by the ASNT Central Certification Program (ACCP), PCN (ISO 9712 compliant), EN 4179, and NAS 410. Our Level II and Level III technicians can perform conventional film radiography, a portable method that is capable of revealing the most microscopic cracks in metallic materials through metallurgical testing.

Close Proximity Radiography (CPR)

In addition to conventional and digital radiography, Element offers Close Proximity Radiography (CPR). The CPR system, also known as “Small Controlled Area Radiography” (SCAR), has been developed as a unique industrial radiography process that does not require evacuations of personnel. Proximity radiography can produce both film and digital imaging. 

Computed Radiography (CR)

Our NDT laboratories also perform Computed Radiography, a method that produces an image in a digital format that can be viewed on any laptop or computer, eliminating the need for chemical processing and costly film storage.

Digital Radiography (DR)

We also have the latest digital radiographic equipment using Digital Detector Arrays (DDA) where images are displayed directly onto a computer screen and can quickly and easily be shared. Understand the difference between Computed Radiography (CR) and Digital Radiography (DR).

Linear accelerator testing (LINAC)

Linear accelerators are used for testing thick and dense materials such as steel. Due to their high performance, they require significantly less time to penetrate the material.

Computed Tomography (CT)

Computed Tomography is the most advanced radiographic testing method that uses an automated detector motion to gather thousands of images at various angles to create a 3D image. The image can be viewed on the screen and further processed with a CAD program or analysis software.

Advantages of radiographic testing:

The advantages of using radiography inspection as your chosen non-destructive testing method.

  • Ability to inspect assembled components
  • Requires minimum surface preparation
  • Detects both subsurface and surface defects
  • Provides a permanent film record of testing
  • Verifies internal flaws in complex structures
  • Conducted by highly trained, certified experts

The Element Advantage

Whether you require on-site field services or in-lab RT laboratory analysis, our global platform of experts and resources delivers the certainty your radiographic inspection projects require. 

Eddy Current Inspection

Eddy current inspection is an efficient and precise nondestructive test method. This type of inspection is particularly helpful in evaluating heat exchangers and aircraft parts and components.

Eddy Current Inspection

The flow of periodic electrical currents in conductors, or probes, creates varying electromagnetic fields. These probes are placed near the surface of the test material and can detect the effects of processing and shaping operations during production, as well as corrosion damage or cracking for most nonmagnetic metals and alloys.

Eddy current testing is a valuable tool for the nondestructive testing and condition monitoring of a large variety of metallic structures, including heat exchanger tubes, aircraft fuselage, and aircraft structural components.

NDT at Element - Eddy Current

Element operates full-service non-destructive testing laboratories that utilize advanced equipment capable of performing quality inspections. Our experts are ready to assist you with your toughest material challenges. 

Liquid Penetrant Inspection (LPI)

Liquid penetrant inspection (LPI), or dye penetrant inspection, is a reliable, efficient, and cost-effective method for detecting surface flaws in welds, castings, and other components that cannot be destroyed. LPI or dye penetrant is a portable surface inspection method, allowing our Engaged Experts to conduct a comprehensive onsite evaluation.

What is Liquid Penetrant Inspection Utilized For?

Liquid penetrant inspection is a valuable tool for evaluating non-ferromagnetic and non-metallic materials. In addition to utilizing dye in checking for defects and cracks, it can also be used to determine other surface characteristics, such as porosity. 

The Dye Penetrant Inspection process

Parts must go through a pre-cleaning process (etch, alkaline, or solvent-cleaning) before the liquid penetrant is applied. After allowing proper dwell time, the excess penetrant is removed from the surface (but not from any possible defects), and the part is dried. Then a developing powder is applied; this developer pulls up the dye that has seeped into cracks or pores, resulting in visible marks or indications that identify surface flaws. Based on the results, an inspector then provides a report with the type, number, and size of defects on a component.

Element’s Liquid Penetrant Inspection (LPI) qualifications 

Our non-destructive testing (NDT) experts are well-trained in liquid penetrant inspection and hold Level II and III certifications from ASNT, among other qualifications. Element provides Type II non-fluorescent NDT services to all of the various commercial and nuclear codes, as well as Type I fluorescent inspection to aerospace, government, nuclear, and after-market applications.
