冷拔高压锅炉钢管由鞍钢无缝钢管厂生产,已有二十二年历史,平均年产量1500吨左右,主要用于制造大中型电站锅炉。该产品自投产以来质量不断提高,具有尺寸公差小,性能稳定等特点,使用性能赶上了西德、日本的同类产品。1.主要技术特点冷拔高压锅炉钢管常用的钢种是20G、15CrMo、12Cr1MoV 等,按 YB529—70技术标准组织生产。为给用户提供满意的产品,生产厂对其化学成份、机械性
Cold-drawn high-pressure boiler pipe produced by the Ansteel seamless steel pipe plant, has 22 years of history, with an average annual output of about 1,500 tons, mainly for the manufacture of large and medium-sized power plant boilers. The quality of the product has been continuously improved since it was put into production, with features such as small size tolerance and stable performance, and its performance has caught up with similar products in West Germany and Japan. 1. The main technical characteristics Cold-drawn high-pressure boiler steel commonly used steel is 20G, 15CrMo, 12Cr1MoV, etc., according to YB529-70 technical standards for production. In order to provide users with satisfactory products, the production plant of its chemical composition, mechanical
