Pipelines are the vital lifelines of the industrial economy, transporting vital energy, water and other essentials needed by households and industry. The integrity of pipeline networks is threatened by cracks and other defects generated during manufacturing, installation and operation of the system. If these defects are not detected in time, then catastrophic failures leading to loss of life and environmental and economic damage can occur.

The objective of this quiz is to evaluate the readers’ understanding of pipeline nondestructive testing (NDT) and ultrasonic testing (UT) methods.
