The severity of external corrosion, degradation and remaining integrity is evaluated using 3D Laser Scanning and Manual Pit Gauging inspection methods

Shawcor experienced technicians perform 3D Laser Scanning and Manual Pit Gauge evaluations to measure the depth of the pitting created due to external corrosion. Every pit is a physical area of thinning material within the pipe wall. A pit of significant size and depth will increase the likelihood of a failure and require a reduction in the safe operating pressure of the asset. 3D Laser Scanning and Manual Pit Gauge evaluations can be used to collect the information in a timely and comprehensive manner while providing an analysis to report and illustrate the severity of the findings.

MANUAL PIT GAUGE EVALUATIONS

Shawcor expert technicians use various manual pit gauges to measure the depth of all pitts, dents and anomalies that are visible on the contact surface-side of the asset. This data can be used with calculation programs to determine the severity rating per ASME B31G, B31G Modified, and Effective Area (RSTRENG) calculations.

3D LASER SCANNING

Shawcor’s technicians use the highly portable Creaform HandyScan 700 to collect millions of data points measuring the corrosion data of any pitting and deformation of any mechanical damage for pipeline integrity. This HandyScan 700 is associated with the PipeCheck software program to produce instant calculations to determine the severity rating per ASME B31G, B31G Modified, and Effective Area (RSTRENG) calculations. 3D Laser Scanning evaluations allow Shawcor Inspection Services to be highly accurate, consistent, and repeatable with the information collected ensuring that your pipeline integrity program has the most reliable data to pass stringent regulatory compliance standards.
