Abstract

In the machining process of sleeve parts by one machine manufacturing shop, it was found that the surface of several steel pipe sleeve parts had linear longitudinally stripe defects and the surface quality was unqualified. After scraping the unqualified sleeve parts, the defects were damaged for analysis. Through metallographic detection, scanning electron microscope(SEM) and energy dispersive spectroscopy(EDS) analysis, the causes of defects were finally found out. There were some small skin warping defects on the surface of the tube billet before drawing. These small defects were lengthened longitudinally along the deformation direction during the drawing process, and finally became the folding defects distributed longitudinally in the extension pipe.

Key words

pipe sleeve / surface analysis / linear trace / folding defect / metalloscope / scanning electron microscope(SEM) / energy dispersive spectroscopy(EDS)
