The DdL-DW2 geometry inspection tool is a pipeline caliper inspection tool designed to detect dents, ovality, wrinkles, buckles, and bore restrictions within pipelines. Geometry inspection tools play an important role in pipeline integrity programs by identifying deformation that may impact pipeline performance or the success of future inline inspections (ILI). Running a geometry inspection tool prior to inline inspection helps verify pipeline conditions and identify restrictions before running more advanced inspection technologies.

Pipeline Cleaning and Inspection Preparation

Proper pipeline cleaning is often performed before running inline inspection tools. Removing debris, wax, and buildup helps inspection tools maintain proper contact with the pipe wall and improves inspection data quality.

Frequently Asked Questions


  • What does a geometry inspection tool detect?

    A geometry inspection tool detects and measures deformation features such as dents, ovality (out-of-round), wrinkles, buckles, bore restrictions, and other geometry changes that can impact integrity and inspection results.

  • Why run a geometry tool before an inline inspection (ILI) run?

    Running a geometry tool before ILI helps identify deformations or restrictions that could affect tool passage, data quality, or inspection planning. It’s commonly used for pre-ILI assessment and verification.

  • Which DdL-DW2 spec sheet should I download?

    Download the spec sheet that matches your pipeline’s nominal pipe size (NPS). If your line has unusual geometry, restrictions, or operating conditions, contact Enduro for confirmation.

  • What pipeline conditions affect geometry tool performance?

    Geometry tool performance depends on line conditions and operations, including pipeline cleanliness, flow stability, speed control, and the presence of debris, restrictions, or complex fittings.

  • Do you provide help selecting the correct tool for our pipeline?

    Yes. Enduro can review your pipeline details (diameter, features, operating conditions, launch/receive setup) and help select the best configuration. Call 800-752-1628 or use the Quick Quote page.
