Abrasive Blasting of the Large Workpieces
Keywords:
abrasive blasting, large workpiece, internal surface finishAbstract
Abrasive blasting of the large workpieces, particularly internal or shaped surfaces, hasa number of technological difficulties. Primarily, this is due to the inaccessibility of the treatment area and not ensure high performance. Scientific substantiation a new method for abrasive blasting, characterized in that the formation of the abrasive mixture occurs directly in the processing zone. This solution allows you to create a sealed area, thereby reducing the abrasive consumption and improves performance. The effective area of application of the developed method is the machining for large diameter of internal surfaces of pipe billets. This technology has been applied to clean the inside surfaces of the pipeline for later diagnosis of defects.
