LaserStream introduced its Bore-Erosion Measurement and Inspection System (BEMIS) laser scanning technology through an exclusive relationship with Laser Techniques Company. The BEMIS laser sensor rotates at high speed as it is driven the length of a tubular, typically generating more than 2,500 data points per revolution. The result is a high-resolution 3D map of the component inner surface. The linear resolution (the tightness of the helix) can be as fine as .010 in. or as loose as 1 in., depending on the application. These data provide information about wall loss (erosion and corrosion), mechanical wear (wireline and coiled tubing), eccentricity, and exact dimensions. Typically, measurements are accurate to ±.002 in. or better. Until recently, this technology has been primarily used by organizations such as the National Aeronautics and Space Administration, the Department of Defense, and nuclear power companies. LaserStream can customize its equipment and software applications to meet specific needs, varying sizes, or different applications (risers, tubing, and casing).
