| Abstract: | The reasons leading to outside bend fault on the surface of steel pipes containing V and N are analyzed through studying the surface fault on partial number strength microalloying seamless steel pipes produced in Angang and the materials of seamless steel pipes, continuous casting slabs and continuous rolling pipe slabs. The methods to improve surface quality of steel pipes are provided.The waste products quantities are greatly reduced by the developed technique. |
