Wireless Transmission Pipe Ultrasonic Flaw Detector
The system is suitable for the automatic detection of various internal and external defects of steel pipes. The principle of ultrasonic flaw detection is that after the ultrasonic wave is coupled into the steel pipe through water, the incident propagation will cause ultrasonic reflection when there is a defect in the pipe. The ultrasonic instrument will alarm the ultrasonic reflected signal after ...

Ultrasonic Testing of Anchor Bolts: A Guide
Industrial anchor bolts are typically exposed to rough conditions and subject to intense pressure while still needing to maintain performance integrity. Because of this, testing is so important. When testing anchor bolts, many manufacturers rely on non-destructive testing (NDT) solutions. NDT helps detect flaws in an anchor bolt both before and after implementation, allowing manufacturers and ...

Ensuring Flightworthiness with Ultrasonic Testing for Jets and Spacecraft
The speed of modern aircraft—whether passenger, commercial, or military—is far beyond what early aviators invented. The power of modern spacecraft exceeds even the boldest imaginations of early sci-fi writers. But speed and power come with a price: the aircraft has to be able to withstand incredible pressures without a single flaw. If something goes wrong, a catastrophe could follow. ...
