Ultrasonic Smart Pigs suit small-diameter pipelines.September 15, 2010 -
Untethered ultrasonic smart pigs, for pipelines and fired heater tubes, inspect straight lines and navigate short radius bends. Operating in several liquid media, units sample 360° of up to 12 miles of tube wall at 2,400 samples/sec, travel velocity of 1-2 fps, and travel measurement resolution of ¼ in. Their transducer offers 3D color-coded representations of wall thickness and units can also provide end-of-life calculations based on nominal thicknesses or previous inspection data.

Advanced inspection for small diameter pipelines and fired heater tubes
NORWELL, MA - Clean Harbors, the leading provider of environmental, energy and industrial services throughout North America, today announced new untethered ultrasonic smart pigs to inspect fired heater tubes and small diameter pipelines. The company has miniaturized and advanced a technology that was previously available only for larger diameter pipelines or had limited data storage capabilities. The new technology supports petroleum, refinery, chemical, paper and other process manufacturing operations.
Detailed Inspections and Reporting
Clean Harbors' smart pig inspects straight lines and navigates short radius one diameter bends in process heaters and plant lines. It inspects up to Schedule 160 pipe in a variety of metallurgies, including but not limited to stainless steel, chromes and standard carbon steel configurations. Vacuum-style fired heaters with multiple pipe diameters can be inspected in addition to hard-to-reach convection sections. The tool operates in several liquid media, but is normally run in water at ambient temperature.
The smart pig samples 360 degrees of up to 12 miles of tube wall (using one battery pack) at a rate of 2,400 samples/second with a travel velocity of one-two feet/second and a travel measurement resolution of ¼ inch. Its custom-designed transducer produces A, B and C scan data, as well as 3-D color-coded representations of wall thickness. It identifies corrosion and erosion for continued monitoring or replacement and takes radial data measurements to prove tube cleanliness. It also records denting, ovality and pipe and tube swelling.
Clean Harbors' smart pig plots wall thicknesses with end-of-life calculations based on either nominal thicknesses or compared to previous inspection data. Powerful software produces preformatted and custom spreadsheet and graphical reports in many formats. All data collected are turned over to the client.
"Clean Harbors' smart pig is a major advance over manual, visual spot checks of a few accessible points," explained Billy Musgraves, Clean Harbors General Manager Inspection Services. "We now offer comprehensive, real-time inspections for previously inaccessible areas and give our clients the ability to inspect the mechanical integrity of every inch of their small diameter pipes and tubes."
