Cylindrical stock is exactly what ultrasonic testing was built to catch defects in before it becomes a finished part — wall-thickness variation, internal voids, laminations. SDI's bar and tube systems range from compact lab units up to continuous-production platforms handling the heaviest billets.
Oil & gas pipeline production, aerospace tube stock, and automotive driveline components are the industries that rely on this line most.
Bar System with Data Logging Acquisition
SDI's entry-level bar inspection platform for smaller lab and low-volume production environments, with full defect data logging built in.
| Configuration | Lab/production bar scanner |
| Data logging | Built-in defect location and length logging |
| Typical use | Bars weighing 20–200 lbs |
Automated Ultrasonic Bar Inspection System with C-Scan Acquisition
Adds a full C-scan acquisition sub-system to automated bar inspection — visualizing defect location and severity across the entire length of the bar in a single pass.
| Configuration | Automated, C-scan acquisition |
| Typical use | Production bar and cylinder inspection |
Bar Inspection Test Frame
A precision test frame with real-time signal monitoring, suited to applications where flaw signal characterization matters as much as throughput.
| Configuration | Fixed test frame |
| Monitoring | Real-time signal display |
| Typical use | R&D and QA validation |
Tube Inspection System with Dual Test Heads
Dual test heads and auto-load/offload keep tube stock moving through inspection without manual handling between cycles — built for continuous production runs.
| Configuration | Dual test head, auto-load/offload |
| Typical use | Tube and pipe production inspection |
Ultrasonic Heavy Duty Bar/Cylinder Inspection System
SDI's largest-capacity bar and cylinder platform, engineered for multi-zone inspection of the heaviest round billets in continuous production.
| Configuration | Heavy duty, multi-zone |
| Typical use | Bars and billets up to 16,000 lbs |
