About NDT Testing
About NDT Testing
According to the steel pipe production standards, the requirements for testing and nondestructive testing is a very important over the years, Tianjin Xinyue keep the principle of the responsible for customer, strictly control the production quality, today we share with you about the knowledge of NDT testing:
The Principle of Ultrasonic Testing
The principle of ultrasonic testing is to make use of the fact that ultrasonic waves can propagate at a certain speed and direction in materials, and will produce reflection when encountering heterogeneous interfaces with different acoustic impedance
The Principle of X-ray Testing
The most important application of X-ray inspection is to detect macroscopic geometric defects (flaw detection) inside the test piece.
The Principle of Magnetic Particle Testing
Magnetic particle inspection is to magnetize the workpiece to be inspected by applying a magnetic field to form a leakage magnetic field on the surface and near-surface defects of the workpiece.
The Principle of penetration testing
Permeation detection is to use a liquid dye on the surface of the test material.
The principle of Eddy current testing
Eddy current testing is a nondestructive testing method based on electromagnetic induction principle
