1·Thus Ductile iron valves can easily replace cast iron or steel valves.
因此球墨铸铁阀门能够方便的替换铸铁或钢阀门。
2·NIBCO Ductile iron valves come standard ANSI B16.42 Class 150 flanges and the same end-to-end dimensions as Class 125 iron or Class 150 steel valves.
美国尼必可球墨铸铁阀门符合ANSI B 16.42标准150磅级法兰和相同端对端尺寸的125磅级铸铁或150磅级钢阀门。
3·In next phases, a ductile iron pipes factory with the production capacity of 2 hundred-thousand tons and a steel factory with the production capacity of 2.5 million tones per annum will be added.
在下一阶段，将继续建成一个年产20万吨的球磨铸管厂和年产250万吨的钢厂。
4·Pump cover material with steel ZG230-450 more, can also be used ductile iron, the latter two materials contrast of wear resistance and hardness and heat resistance to be because the former.
泵体、泵盖的材质采用铸钢ZG230-450的较多，也可以采用球墨铸铁材质，两种材质对比后者的耐磨性和硬度以及耐温性要因为前者。
5·That is, the ductility of the connections ought to improve and the ductile design on steel frame should be realized.
因此，工程界普遍认为梁柱刚性连接有必要改善其节点的延性和对钢框架采用延性设计。
6·Ductile iron, also known as nodular iron, was developed in 1949 as a substitute for steel.
作为钢的替代品，1949年人类开发了球墨铸铁。
7·It was found that the fracture of TWIP steel was typical ductile fracture pattern and its deformation and fracture processes were the formation, growth and coalescence of microvoids.
结果发现，TWIP钢具有典型的延性断裂断口特征，其变形和断裂过程为微孔洞的形核、长大和聚合。
8·By using measurement of mechanical parameters and microscopic observation, the effect of initial damage on the ductile fracture initiation toughness of steel was investigated experimentally.
通过力学参数测量和微观观察研究了初始损伤对钢的延性起裂韧性影响。
9·It is found that the ductile strengthen member (concrete fill steel tube) play an important role to prevent the structure from collapse after the shear walls partially yield.
结果表明，混凝土芯筒的剪力墙屈服后，其内置的延性加强构件(钢管柱)对结构的防倒塌有显著的作用。
10·I was founded in 1994, is a specialized in cast iron, cast steel, alloy cast iron, ductile iron casting processing units.
我公司成立于1994年，是一家专门从事铸铁、铸钢、合金铸铁、球墨铸铁的铸造加工单位。
