Rotating Billet Inspection System (RBIS)

The rotating billet inspection system (RBIS) is a turnkey solution that uses phased array (PA) and eddy current array (ECA) technology integrated into a fully automated testing system to meet stringent requirements for volume and surface inspections. Key benefits include:

• Both volume and surface inspection in a single system
• High throughput that saves you time compared to conventional approaches
• Minimize your dependency on operator skill with automatic calibration
• Get the most out of the system with 2D mapping
• Flexibility to inspect round billets made from carbon steel, stainless steel, aluminum, and titanium as well as black and bright bars
• Fast changeover limits your downtime

Designed to be an easy-to-use solution that provides repeatable results, the system includes:

• Dedicated project management
• Instruments, probes, and mechanical equipment
• Software
• Commissioning, training, and after-sales support

Complete Billet Inspection

Full Body Inspection with Phased Array

While the billet is rotated, the inspection head travels on a gantry along its length. Air cylinders move the wedges down at the beginning of the inspection sequence and up at the end.

The probes are mounted in Olympus water wedges that have many degrees of freedom and pneumatic suspension, helping ensure optimal coupling.

Specific wedges are used for longitudinal and shear waves to inspect both the billet’s volume and subsurface.

Surface Inspection with Eddy Current Array

Surface-breaking defects are inspected using eddy current array. A special probe holder is used to enable in-contact inspection with optimized lift-off for any billet diameter. The probes feature a ceramic face, making them resistant to damage.

High-Quality Results

The system meets the productivity requirements of the metal manufacturing industry while adhering to the highest international quality standards.

Water Wedge

The water wedge’s degrees of freedom and pneumatic suspension enable it to follow the pipe’s movement. The wedge uses an Aqualene membrane that maintains a thin film of water for excellent coupling. The water path inside the wedge remains undisturbed for high repeatability on small reference defects. Wear plates are available to fit the diameter of your billet.
