co2 Pitting 13 Chrome

I am trying to find out if anyone has had much experience with find CO2 pitting on 13 chrome material in full lengths of pipe and the method used to detect that pitting. I have about 16000 feet of pipe to look at with minor pitting .017" to .060" and I am having trouble with my signal to noise ratio just wondering if anyone out there knows or can help with this situation?

Re: co2 Pitting 13 Chrome
Ed,

Have you considered using LASER NDT to inspect the piping? The Laser-Optic Tube Inspection (LOTIS) process can reliably detect and quantify pitting with depths as shallow as +/-0.002" and pit diameters as small as 0.005". Currently there are laser probes built which can inspect piping up to 5.4" ID. Not sure what size your piping is?

For more information you might want to take a look at our web-site which can be found at http://www.qi2.com/field/fsddef.htm

If you have any further questions please contact me at the numbers listed below.

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

This set of two blocks has been specially designed for situations where ultrasonic examination tak
...
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
