| Abstract: | The Production process of heavy calibre thick-wall seamless steel pipes is simply introduced.The steel pipes cold-bending fractures are especially analysed with scanning electron microscope and energy spectrum instrument.The result shows that the inclusions containing Al、Si、S、Ca、Mg and iron oxide are the main reasons leading to inside cold-bending fractures of SA299 heavy calibre thick-wall seamless steel pipes. |
