In-Line Caliper Flaw Detector (CLD): A Precise Solution for Pipeline Inspection

The In-Line Caliper Flaw Detector (CLD) is a sophisticated device designed for accurate and efficient inspection of pipelines. It utilizes advanced technology to measure the internal diameter of pipes, enabling the detection dents, ripples, ovality and other defects in pipeline geometry.

Key Applications:

  • Construction: Guarantees proper and secure pipeline installation.
  • Manufacturing: Ensures the quality of pipes during production.
  • Transportation: Verifies pipeline safety before transportation.
  • Maintenance: Identifies dents, ripples, ovality and other defects in pipeline geometry. Identifies all structural elements of the pipeline: valves, tees, bends and allows you to compile a complete pipe log of the pipeline.
  • Contains an Inertial Measurement Unit, which allows you to build a 3D model of the pipeline in a geographic coordinate system

Benefits of Using the CLD:

  • Unmatched Precision: Delivers highly accurate internal diameter measurements, allowing for the detection of even the most minute flaws.
  • User-Friendly Operation: Features a straightforward interface for efficient and user-friendly operation.
  • Enhanced Efficiency: Streamlines the pipeline inspection process, saving time and resources.
  • Improved Safety: Promotes pipeline safety by facilitating the identification and rectification of potential problems.

  • The recommended barrel dimensions serve as a guideline and may vary based on the specific application.
  • For detailed information on compatible launcher and receiver barrel sizes, please consult the manufacturer's instructions.

Additional Considerations:

  • While the 159 mm diameter is provided as an example for pipe diameter compatibility, the CLD may be suitable for a wider range of pipe sizes depending on the launcher and receiver barrel limitations.
  • It's crucial to strictly adhere to the manufacturer's instructions to ensure safe and effective CLD operation.
  • Regularly scheduled maintenance of the CLD is essential to maintain its accuracy and durability.

By incorporating the CLD into your pipeline inspection procedures, you can gain valuable insights into the condition of your pipelines, enabling proactive maintenance and ensuring their continued safe and reliable operation.
