Ultrasonic Thickness Gauge for Stainless Steel Pipes

The ultrasonic thickness gauge for stainless steel pipes emits ultrasonic waves into the pipe wall through a probe, receives the echoes, calculates the propagation time, and converts it into thickness based on the speed of sound. It is used to measure the wall thickness of stainless steel pipes, detect corrosion or wear, and is applied in pipeline maintenance and manufacturing quality inspection.
Selection
When selecting, consider the measurement range covering the wall thickness, accuracy meeting requirements, probe frequency matching the material, environmental temperature effects, device portability, protection level suitable for the site, valid calibration certificates, and a clear, user-friendly operation interface.

Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions. Dual-element probes offer a smaller dead zone compared to single-element probes, and delay-line probes are suitable for thin-wall and high-temperature applications.
Comparison of Rotational Viscometer and Capillary Rheometer in Testing the Flowability of Resin Processing
The rotational viscometer measures torque via rotor rotation, making it suitable for testing the static or low-shear fluidity of resins under low shear rates, with simple and quick operation. The capillary rheometer, on the other hand, forces samples through a capillary to simulate high-shear processing, providing flow data closer to actual production conditions, but it is more complex and time-consuming to operate.
Ultrasonic thickness gauge for detecting thick coatings and composite coatings.
Ultrasonic thickness gauges measure coating thickness using the principle of ultrasonic pulse reflection, calculating the result based on the propagation time of sound waves in the material and the speed of sound. When detecting thick coatings and composite coatings, challenges such as acoustic attenuation of the material, unknown sound speed, and signal recognition at multi-layer interfaces must be addressed.
