In order to classify pipelines with varying diameters and optimize the development of multi-diameter tools, ROSEN has introduced a simple method: the multi-diameter complexity assessment. This methodology ensures that the correct type and size of multi-diameter tools are chosen for specific pipeline conditions. With its growing fleet of multi-diameter tools, ROSEN provides a methodical solution to the complex problem of inspecting aging multi-diameter pipelines.

The on-site operation and handling of the multi-diameter tools is similar to that of conventional in-line inspection tools.

Advantages of Multi-Diameter ILI Tools

• No longer a need for more costly and time-consuming methods
• Results in significant capital savings
• Provides flexibility to operators in new pipeline construction
• Guarantees smooth propulsion through multi-diameter pipelines
• Designed to transverse long Y-pieces or unusual T-pieces
• Functions in both high and low pipeline operating temperatures
• Can utilize valve bypasses for continuous inspection over long distances
