Like magnetic particle testing, this is a surface-only inspection method that can find imperfections such as cracks, surface porosity, seams, laps, etc. Unlike MT, it can be used on magnetic…
Eddy current testing (ECT) is a procedure commonly used to inspect heat exchanger and boiler tubing. This method uses the principals of electromagnetic induction to detect flaws or wall loss…
Mechanical Integrity (MI) can be defined as the management of critical process equipment to ensure it is designed and installed correctly and that it is operated and maintained properly. MI…
We previously discussed how straight beam ultrasonic testing (UT) can be used for inspection and thickness measurement of plates and other flat objects. Welds cannot usually be inspected with straight…
Ultrasonic Testing (UT) is a volumetric testing method that can detect flaws inside a material without them being open to the surface. Several different forms of UT are commonly used,…
The ASME Section VIII pressure vessel code covers design and fabrication of new equipment. Once a vessel is installed and placed into service, it no longer governs. The American Petroleum…
