Abstract

A tube cutter tool is insertable into a tube for cutting a coupon from a damaged site on the exterior of the tube. Prior to using the tool, the damaged site is first located from the interior of the tube using a multi-coil pancake eddy current test probe. The damaged site is then marked. A fiber optic probe is used to monitor the subsequent cutting procedure which is performed using a hole saw mounted on the tube cutter tool. Prior to completion of the cutting procedure, a drill in the center of the hole saw is drilled into the coupon to hold it in place.

Tube cutter tool and method of use for coupon removal

Patent Application Nachbar, H D; Etten, Jr, M P; Kurowski, P A

It is well known in the art that metal tubes used in heat transfer devices are susceptible to wear, erosion and other degradations which may create weaknesses or other potential failure points. One typical prior art method to determine the cause of damage to a tube involves making a circumferential cut on the tube wall and removing the entire section of the tube having a damaged portion thereon. This method is useful where a straight length portion of the tube has been affected. However, access to more constricted areas and removal of relatively large sections of tubing is limited wheremore » « less

System and method for online inspection of turbines using an optical tube with broadspectrum mirrors

Patent Baleine, Erwan

An optical inspection system for nondestructive internal visual inspection and non-contact infra-red (IR) temperature monitoring of an online, operating power generation turbine. The optical inspection system includes an optical tube having a viewing port, at least one reflective mirror or a mirror array having a reflectivity spectral range from 550 nm to 20 .mu.m, and capable of continuous operation at temperatures greater than 932 degrees Fahrenheit (500 degrees Celsius), and a transparent window with high transmission within the same spectral range mounted distal the viewing port. The same optical mirror array may be used to measure selectively surface temperature ofmore » « less
