Ulrasonic testing is ideally suited for detection of planar disconitinuities (like cracks) that are perpendicularly oriented to the beam direction. Also, the presence of porosity and piping etc. can also be detected. Presence of foreign material (slag etc. entrapped) may also be detected.

Your question is too general. There are specific codes and standards that deal with the most appropriate NDT methods and techniques for different castings. In addition to UT, you may also need to consider Radiographic Testing for some volumetric discontinuities.

Best wishes.

Re: ut
hi friend,
I will suggest u to use angle beam probe. normally selection of probe is depend upon application&accuracy required. when u will use normal probe,may be the defect parallel to sound beam cann't detected this can be avoided by using angle beam probe.
dear in UT there is not any specific type of probe for specific material being tested. The probe remain same but its frequency will change so that it can enter in more dense material. the effect of change of material , u will find in graph of UT i.e. TOF

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
