Considerations for ultrasonic testing of tubes and pipes - TWIDefect sizing techniques must be applied to the inspection of tubes and pipes with extreme care. An accurate geometrical plot of specimen, ultrasonic beam and possible defects should always be constructed prior to, and consulted during, inspection and interpretation. Please contact us for more information. For more information please email:

Why do you need a sensor in a well?

Another important consideration is the condensation of liquid droplets on the inside of the pipe, the sensor will often report the range to these droplets rather than the liquid level. This is because the droplets reflect the sound back to the sensor. Illustration 5 shows this concept. Using a sensor in a still well is common.See all results for this questionWhat is ultrasonic testing?Ultrasonic Testing (UT) is a group of nondestructive examination (NDE) techniques that use short, high-frequency ultrasonic waves to identify flaws in a material. They generally work by emitting waves into a material.See all results for this questionUsing an Ultrasonic Sensor Inside of a Pipe | MaxBotix Inc.Nov 07, 2016 · It is possible to get accurate results in a pipe, however, many factors must be accounted for to achieve success; Many customers have requested the option to mount an ultrasonic sensor in a pipe.

REFERENCES RELATED TO THE ULTRASONIC TESTING OF

The majority of references cover aspects related to ultrasonic testing, however some references only cover the general quality aspects of butt fused joints in polyethylene pipes. Because of the depth and variety of literature found on this subject the references have been grouped under the Process Pipe and Tube Welding | ScienceDirectPipe wall thickness is in the range of 0.6-1.2mm with diameters of 5-40mm. Lengths may be from 50mm to over 1000mm. Pipes may have several bends and they are attached to the engine exterior with bolted or clamped end fittings and if necessary intermediate supporting clips.
