Carbon steel pipe fittings elbow sch40, nominal diameter and wall thickness of elbow pipe fittings.There are two common detection methods: flux leakage method and ultrasonic detection method. Among them, the ultrasonic detection method is to manipulate the pulse reflection principle of the ultrasonic wave to detect the thickness of the tube wall after erosion.

During testing, the probe will emit ultrasonic pulses perpendicular to the inner wall of the elbow. The probe first absorbs the reflected pulse from the inside and outside of the tube wall, and then the probe absorbs the reflected pulse from the outside of the tube. This pulse is between the reflected pulse from the inside and outside of the tube.

The journey distance reflects the thickness of the tube wall. Secondly, the basic principle of flux leakage detection is based on the high permeability of ferromagnetic materials.
