How do you find corrosion under insulation (CUI) and what nondestructive testing (NDT) techniques are best? These are questions conscientious system operators should ask when trying to hold off the costly problem of hidden corrosion in their systems. CUI is one of the most difficult corrosion processes to prevent but adoption of proactive measures, such as the development of an inspection program intended to detect early signs of corrosion and mitigate potential piping failures, is critical. In fact, corrosion is so costly that the National Association of Corrosion Engineers (NACE) estimates that the global cost of corrosion is approximately $2.5...

在无损检测(NDT)领域,从事工业ial radiography is, arguably, one of the most expensive methods to perform. With regard to safety, however, it stands alone due to the risk of exposure to ionizing radiation. Many NDT methods share an inherent safety risk due to environmental hazards, but radiography is the only major method with high-dose radiation concerns. Due to the introduction of digital radiography techniques, those concerns are growing smaller with every innovation. Modern equipment reduces the required overall radiation exposure to fractions of the original dose. This reduction in total dose allows the operation to take place in...

几十年来在非破坏性测试（NDT）行业中，电影一直是选择的射线照相成像方法。它的演化和行业竞争使电影融入了高质量的水平，许多选择几乎需要放射线照相。慢膜用于精细分辨率选项，同时更快的速度涵盖更大或更少的关键材料。今天，我们有许多新的竞争对手试图将替代电影作为行业王。其中许多选项共享一个结果：数字成像。传统到数字图像的过渡是渐进的跳跃和界限。我们都是，可能是......

Throughout my career in NDT consulting, there’s one question that gets asked more frequently as the years go by: “Can our operation change to Computed Radiography?” This question is a bit like asking how a piano works. The basic functions are easily understood, but the actual motions of operation are much more complicated. Like a piano, Computed Radiography has lots of moving parts that are unseen by even a skilled user. Parts that spark little interest from the chair in front of the keyboard. I am no musical master or even a musical novice, however, I can shed light on...
