如何发现绝缘下的腐蚀（CUI）以及什么无损检测（NDT）技术是最好的？这些都是认真负责的系统操作员在试图阻止系统中隐藏的腐蚀这一代价高昂的问题时应该问的问题。CUI是最难防止的腐蚀过程之一，但采取主动措施（如制定旨在检测腐蚀早期迹象和缓解潜在管道故障的检查计划）至关重要。事实上，腐蚀是如此昂贵，以至于美国腐蚀工程师协会（NACE）估计全球腐蚀成本约为2.5美元。。。

In the nondestructive testing (NDT) field, industrial 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...

For decades in the Nondestructive Testing (NDT) industry, film has been the Radiographic imaging method of choice. Its evolution and industry competition has driven film into a high quality-level with many options that cover virtually anything requiring radiography. Slow film is used for fine resolution options while faster speeds cover larger or less critical materials. Today, we have many new competitors attempting to dethrone film as the industry king. Many of these options share a single result: digital imaging. The transition from traditional to digital images has been a gradual one with very small leaps and bounds. We’ve all, likely,...

在我从事无损检测咨询的整个职业生涯中，随着时间的推移，有一个问题被问得越来越频繁：“我们的手术能改成计算机放射成像吗？“这个问题有点像问钢琴是怎么工作的。基本功能很容易理解，但实际操作的动作要复杂得多。像钢琴一样，计算机射线照相术有许多运动部件，即使是熟练的使用者也看不见。键盘前的椅子上那些引起人们兴趣的部分。我不是一个音乐大师，甚至不是一个音乐新手，但是，我可以阐明。。。
