Pipe ovality repair
Webb6.1 The ovality of a pipe bend shall not exceed the ovality required by the governing code. If there is no governing code, the difference between the maximum and minimum diameters shall not exceed 8% of the average measured outside diameter of the straight portion of the pipe unless by mutual agreement between the purchaser and the fabricator. WebbAfter welding metal pipes in the steel industry, a 360° measurement of the pipe is carried out to ensure quality in order to check the diameter, roundness and degree of ovality. Four 2D/3D profile sensors are mounted for this purpose, which combine point clouds with the VisionApp 360 software and thus measure the pipe completely via laser triangulation.
