Probability of Detection for Magnetic Particle NDT

Probability of Detection for Magnetic Particle in NDT In the damage-tolerance approach to airworthiness, fatigue-critical aircraft structure is subject to regular nondestructive inspection (NDI) to prevent catastrophic structural failure. Periodic inspection intervals are determined using knowledge of the minimum crack size that can be reliably detected, together with information on Keep Reading

Pipeline Inspection

In the United States, millions of miles of pipeline carrying everything from water to crude oil. The pipe is vulnerable to attack by internal and external corrosion, cracking, third party damage and manufacturing flaws. If a pipeline carrying water springs a leak bursts, it can be a problem but it Keep Reading

MPI – Basic Principles

MPI  – Basic Principles In theory, magnetic particle inspection (MPI) is a relatively simple concept. It can be considered as a combination of two nondestructive testing methods: magnetic flux leakage testing and visual testing. Consider the case of a bar magnet. It has a magnetic field in and around the Keep Reading

Ultrasonic Testing

Introduction to Ultrasonic: The word ultrasonic combines the Latin roots ultra, meaning ‘beyond’ and sonic, or sound. The sound waves having frequencies above the audible range i.e. above 20000Hz are called ultrasonic waves. Generally these waves are called as high frequency waves. The field of ultrasonics have applications for imaging, Keep Reading
