What is UT Couplant?
A couplant is a material (usually liquid) that facilitates the transmission of ultrasonic energy from the transducer into the test specimen. In contact ultrasonic testing a thin film of oil, glycerin or water is generally used between the transducer and the test surface.
What is UT X?
UT-X® Powder is a cost-effective couplant powder for flaw detection and thickness gaging applications where ferrous corrosion inhibition is required. UT-X Powder retains viscosity on salt caked boiler tubes, corroded pipe, structural steel, steel billets, welds and ship plate.
What is the use of Couplant gel?
Ultrasonic couplants are used in virtually all contact testing applications to facilitate the transmission of sound energy between the transducer and the test piece. Couplants will typically be moderately viscous, nontoxic liquids, gels, or pastes.
What are the disadvantages of ultrasonic testing?
Disadvantages of Ultrasonic Testing Techniques:
- Training is more extensive than other methods.
- More expensive than other methods.
- Difficult to use on thin materials.
- Part Geometry can cause complications.
- Needs relatively smooth surface to couple transducer.

What is the advantage of UT?
There are several advantages of UT that include but are not limited to: High accuracy in ascertaining reflector position and thus estimating size and shape of possible defects. Minor part preparation is needed. The UT flaw detection unit provides instantaneous results.
What are three types of ultrasonic inspection methods?
There are three basic ultrasonic inspection methods: pulse echo, through transmission, and resonance.
