Topographic laser mapping for OD Pipe corrosion


I'm looking for information on a system that provides an x y manipulator that has a laser
attached for topographic mapping. This system will be utilized on 24" to
42" pipe that is under severe SCC attack and will be used in remote
areas in a temperature range of -40 C to +20 C. Minimum umbilical
length would be around 25".

Re: Topographic laser mapping for OD Pipe corrosion
Mr. Hermanutz,

QUEST Integrated, Inc. in Kent, Washington, USA builds several types of laser based NDT equipment. Two models (400N & 200K) of the Laser-Optic Tube Inspection System (LOTIS) apply Laser Profilometry to map the interior surface of tubes covering ID ranges between 0.50" to 5.5". When the LOTIS is finished mapping the tubes interior surface the software allows the inspection technician to view the data in several high resolution views, such as Plan View, 3D Isometric, Axial & Circumferential Cross Sectional.

At one time QUEST considered building a external pipe laser mapping system for Alyeska Pipeline to use on the Alaskan Transatlantic pipeline but that never materialized.

If you want additional information with regards to QUEST’s various laser mapping equipment you can visit http://www.qi2.com or call (253) 872-1275.

Dear Mr. Hermanutz,
I'm involved in the design and development of laser-based NDT systems. I would ask the following question: Are you trying to obtain a 3-D profile? Or are you trying to locate the surface-breaking cracks? We have developed a laser-scanning method (patent pending) that might solve your problem. Please check our web site at nwra.com or contact me directly at doyle@nwra.com

I look forward to discussing your application and perhaps assisting you in a solution.

Best regards,

James Doyle
Manager, NDT Systems
