The XR Spider is an automated ultrasonic corrosion-mapping scanner engineered for high-resolution C-scan imaging on pipelines, vessels, and large-diameter tanks.
Built for rugged field deployment, it delivers consistent coupling, repeatable data, and faster coverage — now supported by a built-in scan-time and pass-count estimator for planning inspection efficiency.
Real-World Inspection Challenges
Inspecting large-diameter piping and storage tanks is labor-intensive.
Manual scanning introduces uneven coverage, variable coupling, and operator fatigue that lead to inconsistent wall-thickness data.
When schedules tighten, every re-scan adds cost, delays, and uncertainty.
For Level II technicians, setup time and scanner reliability directly affect turnaround success.
For Level III managers, data density and repeatability determine inspection credibility and code compliance.
For inspection-service owners, fewer re-scans and reduced rental dependence translate into better ROI and uptime.
How the XR Spider Solves It
Designed and manufactured in Texas, the XR Spider is a fully automated raster scanner purpose-built for corrosion-mapping applications.
Its drive system and probe carriage maintain constant coupling pressure and orientation across curved surfaces without manual adjustment.
The scanner performs circumferential and longitudinal passes on assets ranging from 2 in pipe OD to vessels over 10 m in diameter, maintaining accurate position encoding throughout the scan.
Key Features
-
Automated Raster Motion – Provides uniform, encoded motion for C-scan corrosion mapping.
-
Self-Aligning Probe Assembly – Maintains perpendicular coupling on curved geometries for consistent amplitude.
-
Touchscreen Control Interface – Integrated display enables precise control and live monitoring during automated passes.
-
Rugged Construction – Machined 6061-T6 aluminum and 303 stainless steel with sealed encoders for field durability.
-
Constant-Force Spring Mechanism – Applies uniform probe pressure across all radii without adjustment.
-
System Integration – Compatible with ScanTech’s Analyst XR C-Scan Software and Batt Pack Pro controller.
These design elements eliminate slippage, uneven pressure, and data drift common in belt- or chain-driven scanners.
Plan Your Inspection Time
Use the interactive tool below to estimate total scan time and pass count for your tank or pipeline based on length, pass width, and resolution settings.
This helps inspection teams plan coverage and crew allocation before mobilizing to the field.
Scan Time & Pass-Count Estimator
Enter asset length and pass width in inches, feet, or meters. The other fields auto-convert.

Field-Ready Design for Every Role
For Technicians
Fast setup, no tool changes, and reliable coupling — even on vertical or overhead surfaces. Joystick control provides responsive motion for both automated and manual scans.
For Maintenance Managers / Level III Inspectors
Delivers high-resolution, repeatable C-scan data with full compliance confidence for API 653 and ASME B31G requirements.
For Service Company Owners
Minimizes project downtime and equipment rental cycles, reducing cost per inspection and maximizing uptime across crews and sites.
