True tube profile measurement system Solution for cleaning inside

LIMAB, Sweden, manufactures laser measurement systems for the steel industry and is a pioneer in non-contact laser measurement, with sensor development, engineering, design and manufacturing all done in-house. It has developed several measurement solutions for the steel industry such as diameter, ovality, length, thickness and width measurement. The company presents two different key systems for diameter and ovality/ shape measurement: HotProfiler and Tubeprofiler. HotProfiler is a non- contact laser measuring system for hot and cold applications in bar and tube rolling mills. The system can be equipped with 18 sensors placed in an oscillating measurement frame. Tubeprofiler is a non- oscillating measurement system, equipped with up to 18 sensors, for hot and cold applications in bar, tube and pipe mills. The system can easily measure on round, square, hexagonal, flat or any other type of tubes. The unique design of measuring using distance sensors mounted around the tube will detect any type of shape error, which means that there are no

blind zones. All measured dimensions are processed and displayed in the operator software. The results are shown as real- time numbers, trend graphs as well as in 2D and 3D graphs for easy viewing. The database provides an excellent source of production data for long-term monitoring and process improvements and will output key dimensions and alarm signals if any of the tolerance or warning limits are exceeded. The Hotprofiler and the TubeProfiler are very easy to install in the existing line and easy to relocate to other parts of the mill, using the built-in lifting hooks and the quick change electrical connectors. The core part of the system is the laser sensor itself, which has no moving parts for zero maintenance. The sensors are completely sealed with digital processor inside and capable of withstanding hot and dirty industrial environments.

of tubes and pipes TUBE Clean GmbH is a Swiss manufacturer and distributor of equipment for hose, tube and pipe cleaning, providing complete and fully integrated solutions. The company states that the Bison 4000 W/D is the first plant available in the industry that allows a combined wet and dry cleaning of tubes and pipes. The machine can clean inside diameters from 1.8 to 32mm, and the company claims it is fast (intervals of two seconds) and environmentally friendly. All necessary parameters are fed into the system via a touch-screen. The modular design allows for customer- specific solutions or integration into existing processing lines.
