True it may detect it quickly and accurately but I think you would be better sizing with Pulse Echon I suggest you consult the NACE Document of assessment of pressure equipment damaged by HIC. Mikes comment that once the flaws are accurately sized you can employ an engineer experienced in FFS principles such as API RP 579 is very accurate. Be careful HIC and SOHIC was not dealt with in the first edition of RP 579 in a clear manner. You will have to consider whether you are looking at a blister or through wall cracking hence the emphasis on an 'experienced engineer'.    Reply  Translate  Close   Mike Trinidad Consultant, LMATS Pty Ltd , Australia, Joined Jan 2003, 138 Mike Trinidad Consultant, LMATS Pty Ltd , Australia, Joined Jan 2003 138 05:04 Aug-26-2004 Re: HIC G'Day John Could you tell me the NACE reference, I might get it for a bit of light reading. ToFD gets asked for a lot for this application in the middle east I thought it was based upon a DNV specification but now looking back through information it appears to be a BS standard.

Product Spotlight ISAFE3 Intrinsically Safe Sensor System StandVallen-Systeme GmbH 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. > 2 Showcases Ultrasonic Testing Immersion Tanks with Unmatched Scanning Features StandTecScan Systems TecScan’s non-destructive testing Ultrasonic Immersion Tanks & scanners are designed for high pe ... rformance and demanding NDT testing applications.
