Prove-up inspection on coated pipe.

A welded SAW pipe with OD/ID coated pipe what would be my distance and v path 1st, 2nd, & 3rd leg in mm? I'm thinking the OD coating is about 18 mm and ID is like paint brush thin.
Epoch unit - 1/2 inch prob 3.5 Mhz. transducer - set up only on a 1/16'' drill hole on.

I would hope there are errors in your initial post. First off, I highly doubt you have almost 3/4" of external coating to contend with. Secondly, code compliant shear wave through any discernible volume of coating (or paint) is not an acceptable inspection technique in my experience. Finally....maybe we'd need refracted angle and nominal WT to complete skip distance equations?? If you are the technician why can't you do the math?

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.
