Inline measurement of tube geometry

Portable outside clamping pipe facing machine THE Protem OHSB-C 6-14 is designed to carry out bevels or compound bevels by copying. A carriage with hydraulic radial movement, mounted on the tool holder plate, enables the machine to perform bevelling works while using a copying cam. The tool holder is equipped with carbide plates. The maximum wall thickness of tube is 60mm on a height of bevel lower than 30mm and a maximum angle of 37°. The clamping range is 6" to 14", and the maximum tool holder plate speed is 170rpm.

Fair visitors also had 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.

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 laser scanners were 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 millimetres through to more than one metre. AT Tube 2010 in Düsseldorf LAP presented laser systems for inline measurement of the diameter, straightness and contour of tubes. LAP for the first time showcased 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.
