Helix-XT II IRIS

• The Helix-XT II is an ultrasonic based system for inspecting ferrous and non-ferrous tubes from the inside. It is based on the Internal Rotating Inspection System (IRIS), which can be applied on almost any material.
• With the Helix-XT II, accurate thickness measurements can be taken at any location along the tube, so small changes in thickness are measurable and the exact location of pitting and corrosion can be determined.
• The system uses an immersion pulse echo technique in which a stream of water is used to spin a turbine containing the transducer.
• The turbine rotates a mirror, set at 45 degrees, to reflect the ultrasonic pulses radially into the tube wall.
• Reflections from the inner and outer walls of the tube follow the same path back to the transducer. The time interval between the first echo–the inner wall–and the second echo–the outer tube wall–measures the tube’s wall thickness.
