RTIS: Rotating Tube Inspection System

The rotating tube inspection system (RTIS) is a turnkey solution that uses phased array probes integrated into a fully automated testing system to meet stringent requirements for volume and surface inspections. Key benefits include:

• Minimize your dependency on operator skill with automatic calibration
• Detect defects at production speed with calibration check
• Familiar to major oil companies
• Detects oblique defects to meet current and pending industry standards
• Get the most out of the system with 2D mapping and end-of-tube inspection capabilities

Designed to be an easy-to-use solution for helping ensure the quality of seamless and electric resistance welded tubes, the system includes:

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

Full Body Tube Inspection

Inspect for longitudinal, transverse, oblique, and lamination defects, and measure wall thickness.

• Novel water wedge enables many degrees of freedom to accommodate pipe movement and provide excellent coupling
• Design leaves only small untested tube ends
• Automatic calibration for repeatable results
• High sensitivity on small reference defects with a signal-to-noise ratio greater than 12 dB
• Can be used to fulfill testing regulations (API-5CT and API-5L)

Maximize Your Productivity

The system is adaptable and can be configured to suit different types of inspections.

• The number of inspection heads or electronics can be adapted to meet the required productivity level
• Up to four apertures per phased array probe can be fired simultaneously
• Large mechanical scan overlap covering up to 120 mm/r

Automatic Calibration

To achieve a thorough inspection, each phased array probe must be calibrated. During calibration, the apertures of each probe pass over a known defect, and the probe’s gain level is automatically adjusted. This feature enables users to easily perform and validate a precise calibration of each focal law, saving time without relying on the user’s skill.

• All probes can be calibrated in a single automatic sequence
• Calibration check performed under normal production conditions
• Each reference defect is validated to help ensure they’re detected above the alarm level
• Results are displayed in an easy-to-interpret strip chart and weld mapping view
