It’s been nine years since a heat exchanger burst at an oil refinery in Anacortes, WA, fatally injuring seven workers and bringing renewed attention to the risks of high-temperature hydrogen attack (HTHA).

Over the last 10 to 15 years, NDT methods have grown smarter and smarter. New methods have been developed and old methods have been improved. Some of today’s NDT is leaps and bounds ahead of where it used to be. 

Nondestructive testing (NDT) is the most important industry you’ve never heard of. That’s how I typically start a STEM (science, technology, engineering, and math) demonstration.

Titan Tool Supply, Inc. announced the introduction of its new TVS-35 Series Videoscope to provide remote visual inspection for aviation maintenance, casting and cavity inspection, diesel and gasoline engine repair, or locomotive and ship maintenance. 

Building on the previous model, the U41 brings 14 times the data resolution, performs data ac-quisition 10 times faster and the ability to inspect coating twice as thick as before. These benefits promise to deliver increased revenues and a quick return on investment for our customers.

What is Industry 4.0? This buzzword seems to have been thrown around for quite some time now. How is it affecting today’s NDT manufacturing processes compared to the past? What new technologies have risen from Industry 4.0 in the past few years to benefit NDT? To answer all these questions, it is important to look back and understand how it came to be.

According to ASTM E1316-17a and NET.net, a flaw is defined as ‘‘an imperfection or discontinuity that may be detectable by nondestructive testing and is not necessarily rejectable.” 

This article will list and explain why each magnetic particle inspection accessory is needed to validate the system performance of an inspection.

The dye penetrant method of inspection is a nondestructive test for defects open to the surface. It may be used on such materials as aluminum, magnesium, brass, copper, cast iron, steel, stainless steel, carbides, stellite, certain plastics and ceramics. 

First, a little history. The alternating current field measurement (ACFM) nondestructive testing technique was developed in the ‘80s to detect and estimate penetration depth of fatigue cracks in underwater welded tubular intersections of offshore oil platforms.
