Russell NDE Systems Inc. has created an adaptable “Bracelet Probe” (BP) that can adjust quickly and effortlessly to any size of insulated pipe, starting at 3”. The bracelet probe provides a total end to end solution for all of your insulated and fireproofed pipes.
The BP contains sensitive detectors that cover a 10” wide scan path as it is rolled along the exterior of the insulated or fire-proofed pipe or pressure vessel. The detectors measure fluctuations in the electromagnetic (EM) field from an exciter coil that has energized the pipe.
The pipe acts as a conduit for the AC magnetic fields; however, disparities in its thickness impact the effectiveness of how the pipe conducts the fields. In places where the pipe wall is thinner, it cannot carry as much magnetic energy; therefore, the magnetic field around the BP becomes more robust, enabling the corrosion-under-insulation (CUI) to be sensed and sized.
Data from the BP is then fed to a lap-top computer which both exhibits and instantly records the condition of the pipe under the insulation. Screen snapshots can be saved of the 3D color-maps, strip charts and voltage planes which are used to size the CUI.
- Scan at up to 12 feet per minute.
- Horizontal and vertical pipes.
- Fireproofed sphere legs.
- Fireproofed or insulated vessels and skirts.
- 10” wide scans cover the whole pipe in a few quadrants.
Don’t let corrosion under fireproofing (CUF) deteriorate the legs holding up your gas storage spheres: Inspect for CUF using either the standard Bracelet Probe or the super-large Bracelet Probe used with our patented robotic crawler.
