6物理性能合金管的分类情况(1)无缝钢管因其制造工艺不同,又分为热轧(挤压)无缝钢管和冷拔(轧)无缝钢管两种。冷拔(轧)管又分为圆形管和异形管两种。其中进口管占国内总消费量的27.69%,石油管进口量约占无缝钢管总进口量的大约70%。从日本进口的石油管占总进口量一半以上。中国大的石油套管生产基地——天津钢管公司2000年的钢管产品出来为52.20万吨,其中石油套管产量为36.41万吨。套管占全国石油产量的一半以上。在产量和销售量上都占中国套管市场的位。舟山定海区2.种类20锅炉管按所承受的高温性能分为一般锅炉管和高压锅炉管。无论一般锅炉管或高压锅炉管按其用途要求不同又可分为各种钢管。T91合金管T91合金管,T91钢是美国国立像树岭实验室和美国燃烧工程公司冶金材料实验室合作研制的新型马氏体耐热钢。它是在9Cr1MoV钢的基础上降低含碳量,严格限制硫、磷的含量,添加少量的钒、铌元素进行合金化。根据ASTM213/A213M-85C,T91钢的化学成份见表1。黔南。2.种类锅炉管按所承受的高温性能分为一般锅炉管和高压锅炉管。无论一般锅炉管或高压锅炉管按其用途要求不同又可分为各种钢管。级,是不做冲击;Q345B级,是20度常温冲击;Q345C级,是0度冲击;Q345D级,是-20度冲击;Q345E级,是-40度冲击。在不同的冲击温度,冲击的数值也有所不同。合金管有大口径合金管,厚壁合金管,高压合金管,合金法兰,合金弯头,P91合金管和无缝钢管,另外化肥专用管也非常常见。
