What are Pacific Scientific’s x-ray capabilities? What quality level can we achieve? Do we use film or digital radiography? Get the answers in this new x-ray FAQ.
Frequently Asked Questions
Pacific Scientific Energetic Materials Company (PacSci EMC) has state-of-the-art radiographic and non-destructive test capabilities, including x-ray cabinets, x-ray walk-in bays and a highly qualified staff. We are able to achieve a quality level of 2-2T minimum for all radiographic images, providing a high level of clarity on even the smallest detail. This allows us to check internal components for proper assembly and alignment, and we can even see detailed images of pyrotechnic powders after they’ve been pressed and consolidated.
Both. We use conventional film x-ray, digital x-ray and neutron radiography to get an inside view of our assemblies both during and after manufacturing. We are, however, in the process of making a full transition to digital x-ray. Compared to film, digital x-ray delivers a 300 percent increase in throughput, allows us to see more detail in fewer shots and enables better failure investigations.
Our x-ray capabilities and procedures are compliant with the leading industry standards for aerospace, including ASTM, NADCAP and NAS 410. In fact, many of our x-ray practices exceed conventional requirements, and we are helping advance the industry’s use of and best practices for digital radiography.
We can x-ray parts that are very small or very large. Our x-ray cabinets and walk-in bays have the ability to see through 1.5 inches of steel, which far exceeds the thickness of most assemblies we build. And a special interlock system in one of our bays allows for configurations up to 7 feet in length. The smallest defect detectable varies from unit to unit, but typically can be measured as small as 0.003 inches for film, and 0.005 inches for digital. Our digital systems have a resolution of 200 microns, and can resolve up to 8 line pairs per millimeter (lp/mm).
We have three Level 3 radiographers, three Level 2 radiographers and four Level 1 radiographers on staff with more than a half century of combined experience. Our Level 3 radiographers have an in-depth knowledge of castings, weldments, composites and pyrotechnics. Our staff has also been trained by the author of the ASTM standard for N-Ray and can interpret neutron radiographs.
No. We conduct all radiographic testing and analysis in-house. This allows us to minimize the cost for our customers while conducting the most rigorous and advanced testing possible. We meet or exceed all industry standards, and our transition to all-digital radiography is helping push those standards forward.
In addition to certified x-ray and metrology labs, our facilities include an engineering lab, model and machine shop, clean rooms and a full range of test equipment. We bring a scientific approach to every project, calculating system reliability through trade studies, mathematical modeling, in-depth analyses and rigorous testing. Many of our materials, devices and solutions deliver 99.999 percent reliability or better.
PacSci EMC is an integral contributor to countless space, defense, aircraft and oil and gas programs. Our long history of success is largely built on the reliability and safety of the solutions we create, customize and deliver. Many of the world’s leading companies and institutions—including the U.S. Federal Government, NASA, Lockheed Martin, Boeing, Halliburton, Raytheon, Northrop Grumman, Airbus and Schlumberger—have trusted PscSci EMC for their mission-critical needs.
