LAP releases new laser measure that captures the contour of the entire cross section LAP laser, a supplier of systems that increase quality and efficiency through laser projection and laser measurement, has announced its new tube end check measuring system for capturing the geometry of tube ends. Using sensors mounted on a robot arm, the in-line laser measurement captures the entire geometry of each tube end in-line and in time with production, making it possible to check each individual tube instead of doing spot checks. According to LAP, depending on the setup, the tube end check measures the inside and outside diameter, wall thickness and ovality, as well as the form of the chamfers and the perpendicularity of the saw cut. LAP developed it for use in adjusting and final checks of seamless or welded tubing with outside diameters up to 1500mm or more. The system is completely integrated into the production process and can accurately measure the ends of each individual tube obviating the need for manual offline random sampling previously used, which could often only be applied to a small percentage of the tubes. The system detects all tubes in-line that do not meet specifications which eliminates the high costs of transporting faulty tubes back and forth if deviations are discovered only by the end user. The results also allow conclusions to be drawn about important production process parameters. For example, when rolling seamless tubes, the rolling stand settings can be optimised. A statement from LAP said: “When building pipelines that will be subjected to high pressures, it is important that the ends of tubes are perfectly aligned for welding. Perfect roundness and precise adherence to the specified diameter and wall thickness are critical here. Tube end check delivers all the necessary measurement values from a single pass of the sensor head.”
