Pipeline Mechanical Damage Assessment ASME B31G Compliant

What the industry needs

Pipelines in service need to be inspected on-site to assess the level of denting that they have suffered from, as well as their remaining service life.

While pipeline network’s integrity must be insured, costs also need to be kept as low as possible. Considering these factors, pipelines operators are looking for portability, measurement speed, data storage, and repeatability when choosing an inspection device.

Creaform’s answer

Pipecheck software module for mechanical damage assessment

Creaform’s solution includes a HandySCAN 3D laser scanner and the Pipecheck data acquisition/analysis software for mechanical damage assessment. Pipecheck is an innovative, intuitive and highly-effective alternative to traditional NDT methods most widely-used in this field.

This is the first solution to perform two types of inspection for mechanical damage; a depth-based approach and a strain-based approach are available. The strain-based approach is fully compatible with the ASME B31.8 standard.

Benefits of the solution

TRUaccuracy: Accurate measurements in real life operating conditions

  • Metrology-grade measurements: A dynamic link between the pipe and scanner preserves accuracy and resolution in any field conditions, including vibrating environment.
  • High quality results: within a ± 50 micron accuracy.
  • TRUaccuracy on the pipe: Enhanced virtual pit gauge capabilities. Pit gauge configuration automatically adapted near welds to ensure the most accurate measurement.
  • In-line Correlation: Assess ILI performances by comparing pig data against Pipecheck data to help determine with more precision the sites that actually need to be dug.
  • Corrosion depth inside a mechanical damage: Unique and sophisticated tools to extract corrosion depth inside a mechanical damage.

TRUportability: 3D scanning wherever you need to go

  • On-the-go scanning: Take it from place to place or use it in-house or on-site.
  • Lightweight and small: weighs 0.85 kg; can reach confined areas. Fits into a carry-on.

Speed: Fastest path from physical objects to your design or inspection workflow

  • Scanning speed: 80 times faster than pit gauge technique.
  • Self-positioning device: No need for encoders or bulky mechanical scanners to reference the data.
  • On-site reporting: Results generated within a few minutes.

TRUsimplicity: Very simple 3D scanning process

  • User-friendly: Both the scanning process and the analysis are intuitive, regardless of the inspector’s skills.
  • Follows code regulation (ASME B31.8)
  • Real-time visualization: Thanks to VXremote, the Creaform optimized remote desktop application, data acquisition can be viewed in real time.
  • Flexible: Makes it possible to reach confined areas
  • Simple: Easy and quick to learn.

Depth-based assessment :

  • Maximum depth measurement using straight edge technique in both directions
  • Automatic maximum depth detection
  • Automatic creation of 2D cross-sections
  • 3D and 2D color mapping
  • Depth-over-diameter ratio
  • Maximum diameter at 90 degrees of the dent
  • Length and width measurements for each dent
  • Multiple dent analysis

Strain-based assessment:

  • Automatic maximum strain detection
  • 3D and 2D color mapping
  • Circumferential bending stress
  • Longitudinal bending strain
  • Longitudinal extensional strain
  • Total strain on the pipe interior surface
  • Total strain on the pipe exterior surface
  • Maximum effective strain
