Boiler Tube Inspections

Generating Banks and Tubular Air Heaters
  • TesTex, Inc. leads the way in drum-to-drum boiler inspections, employing the highly advanced Triton II RFET Inspection System. This state-of-the-art technology enables comprehensive full-length tube inspections from either the mud drum or steam drum, ensuring thorough evaluations. The Triton II RFET Inspection System features a flexible probe design, allowing for flaw detection and quantification not only in straight sections but also in the bends of generating tubes. Additionally, TesTex extends its expertise to inspect tubular air heaters when present on specific boilers. Experience the unmatched precision and reliability of TesTex’s inspection services, ensuring the optimal performance and safety of drum-to-drum boilers.

Waterwalls, Super Heaters and Reheaters

  • TesTex, Inc. leads the industry in inspecting larger industrial and utility boilers, employing the highly advanced Triton II LFET Tube Scanning System and leveraging the principles of the Low Frequency Electromagnetic Technique (LFET). This powerful combination allows for the detection of both internal diameter (ID) and outer diameter (OD) flaws on the hot side of the tube.

    The Triton II LFET system facilitates a seamless and continuous 120° scan of the tube surface with a single pass of the scanner, ensuring comprehensive coverage. Any non-accessible areas, including bends, viewports, and sootblowers, that cannot be scanned are meticulously spot checked using ultrasonic testing (UT), ensuring a thorough and complete inspection.

    Typically, LFET inspections in gas and oil boilers require no surface preparation, streamlining the inspection process. However, in boilers utilizing coal as a fuel source, a high-pressure water blasting may be necessary to prepare the surface for the LFET inspection.

    Trust TesTex, Inc. to deliver unparalleled inspection services for larger industrial and utility boilers. Our cutting-edge technology and expertise ensure precise and reliable detection of flaws, enhancing the performance, safety, and integrity of these critical systems.
