Detecting, quantifying, and sizing indications characterized as a “crack” in critical equipment have long been the global benchmark of asset integrity programs. Therefore, the increased precision that inspection programs obtain using advanced technologies can dynamically improve the overall assessment.

Nondestructive Testing (NDT) makes up the majority of testing performed in our industry. There many different types of nondestructive testing techniques. Each method has its own advantages and disadvantages; each can detect different types of flaws. Some are simple to perform, others are difficult. Some are used on several different types of equipment, others are more restricted.

This is the second of two articles published in Inspectioneering Journal discussing the value of hydrogen bake-outs. Our first article was published in the May/June 2013 issue and received a great response from the Inspectioneering community. In this piece, we will continue the discussion and touch on some new technologies used to enhance the bake-out process.

Over the past 100 years, Nondestructive testing has made tremendous advances. New NDT methods have been introduced, while old "tried and true" methods continue to be improved. Although some NDT methods have drastically changed or "evolved" over time, the principle behind each method has remained the same; "To ensure the safety and integrity of manufactured items or goods."

Optimal cleaning to an "inspection clean" status ensures operational efficiency and a longer duration between heat exchanger cleaning requirements. Fouling left behind after inadequate cleaning activities will attract additional fouling at a greater pace once put back into service, leading to reduced heat transfer and a negative impact on production.

Exactly two years ago, an interview with John Nyholt appeared in the “IJ”. New ground will be covered in this interchange. We at the IJ thought it might be valuable to spend some time chatting about his background, challenges he has faced recently and what he feels are some of the biggest challenges ahead for the Inspectioneering® community.
