Immersion UT can be used for a wide range of wall thickness and material types, making it a suitable testing method for a variety of applications and industries. .
Re: What is the Minimum thickness limit for manual UT In Reply to S.V.Swamy at 08:13 Dec-06-2009. Dear sir. I am as a ut technician, i was since work in qatar, cna you help me, i have on e doubt ,ultrasonic testing for minimum thickness in normal probe 0 degree ,tr probe and angle probe ,how much minimum thickness,The minimum thickness noted in this standard is 8mm. However there are an increasing . Conventional ultrasonic testing (according to BS EN ISO 17640) (1) limits thicknesses that can be examined to less than 8mm. Similarly, the draft phased array standard BS . case where ultrasonic methods have been developed for a thin wall has been given byFigure 1: Typical API QUTE-TM Test Specimen Grid 7.1.4 The ultrasonic thickness examination of each test specimen shall be performed in each grading unit. 7.1.5 Scan each grading unit to determine the area(s) of corrosion. 7.1.6 Determine the minimum remaining wall thickness measurement for each grading unit.
The minimum thickness noted in this standard is 8mm. However there are an increasing number of applications involving smaller thicknesses (e.g containments) and these cannot strictly be inspected by these methods. This paper describes a series of experiments of conventional ultrasonic and phased array testing on thin butt
Efficient Wall Thickness Measurement with Ultrasonic Testing. In order to make the most out of your wall thickness measurement testing, you need the right ultrasonic testing equipment: a full suite of scanners, instrumentation, software, and auxiliary tools that can get the job done right.

This includes inspectors testing critical parts like aircraft turbine blades for wear and maintenance crews checking pipes and tanks for in-service .
Re: minimum thickness for ultrasonic testing as per B31.3 In Reply to ashish at 09:54 Nov-23-2016 (Opening). Hi Ashish. ASME B31.3 does not indicate any minimum weld thickness for ultrasonic examination. Having said that, the minimum thickness will be that which allows the technique to be used (for conventional technique, about 6 mm)ISO 9712 Non-destructive Testing—Qualification and Cer-tification of NDT Personnel 2.4 AIA Standard:6 NAS 410 Certification and Qualification of Nondestructive Testing Personnel 1 This practice is under the jurisdiction of ASTM Committee E07 on Nonde-structive Testing and is the direct responsibility of Subcommittee E07.06 on Ultrasonic .ultrasonic inspection dependent on flaw orientation and weld configuration. Radiography, magnetic particle, and penetrants have been used in weld testing for many years and are still the primary test methods. Fig. 6. Weld configuration must be considered prior to inspection.
