Measuring Stainless overlay 309L, 347L, 317L,316 etc.

Hello from South Carolina!!! well, once a year I go out to you all for you opinons on the above subject. Is there a system out there that can measure the thickness of Austentic overlay(ferrite)0.8 to 7.8 and it will vary. The welding application can vary also, but it is mostly automated. The backing is SA 285C or 516-70 mild steel (pressure vessels)or SA210 boiler tubes.For UT, the Z's factor is only 2. For magnetic induction or eddy current, the ferrite is the problem. We still measure befor overlay and after. The thickness will range from 1mm to 12mm.

M.C. Macke.

In response to Mike Macke's question a few weeks ago Dinsley Devices and Inspection Software have recently installed an automated system to measure Inconel cladding in the bore of 125mm - 300mm carbon steel pipe. Cladding thickness 0mm - 10mm, +/- 0.1mm. Should be suitable for other similar materials.

AIS229 - Multipurpose Real Time System

Latest standard & automatic real time system developed by Balteau. The AIS229 has been designed to
do series inspection in a wide variety of industry. Composed of a shielded cabinet, 5 axis manipulator, x-ray generator and tubehead from 160kV to 225kV, a fl at panel & much more, the AIS229 is most certainly one of the most multipurpose RTR system available on the market.


Very Powerful Superior Performance Extremely Portable Smart Phased Array Ultrasonic Flaw Detector an
d Recorder with 2 Conventional UT and TOFD Channels uniquely combines PA, single- and multi-channel conventional UT, and TOFD modalities providing 100% raw data recording and imaging. Suitable for all kinds of every-day ultrasonic inspections

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.


The FlexoFORM™ solution integrates flexible phased array probe technology in a scanner to solv
e the challenges that come with inspecting pipe elbows. When combined with a water column, this solution can be used to collect easy-to-interpret data on elbows with diameters ranging from 4.5 in. OD up to flat and offers many benefits.
