Inline measurement of tube geometry

At Tube LAP will present laser systems for inline measurement of the diameter, straightness and contour of tubes. LAP is for the first time showcasing its new “ProfileCheck” system, a light-section based profile measuring solution for cold and hot applications. It is the ideal solution for rolling mill operators looking for a way to measure with utmost accuracy the entire profile around the complete circumference of the rolling stock. Another novelty is the “StraightCheck” system, an inline straightness gauge that derives the straightness values from measurements of the tube diameter. LAP will also have on display the complete array of systems for the measurement of tube and wire diameters. The LAP systems are designed for a wide range of different measuring tasks and individual line-specific factors. For example, the Antaris Scan SCAN laser scanners will be on display as well as camera systems with a backlight unit and the laser scan micrometers of the new Metis series, developed for a wide span of diameters from just a few millimeters through to more than one meter. Fair visitors will also have the opportunity to see a presentation of the new tube end gauge which checks the tube ends for API-compliance. While being mounted on the arm of a robot, a laser triangulation sensor measures the inner and outer contours and the wall thickness of tube ends during a 360-degree turn of the robot arm.
