Anqing Laiwu Steel production 29 thick X52 pipeline steel

Knowledge of domestic and international pipeline specification Pipeline There are no pipelines toughness index of steel, only the pipes have specific requirements: (1) Minimum temperature (-5 ℃) DWTT≥85% SA; (2) the lowest temperature (-5 ℃) Charpy impact energy ≥145J. Pipeline technical conditions commonly used American Petroleum Institute standard APISpec5L, but the domestic user's specific project or specific orders and technical conditions are often much more stringent than the API standard. Smelting technology with more stringent requirements, technical difficulties focused on: 1) the impurity element content control; 2) inclusion control; 3) a narrow composition control.
