      2019年我国nd钢管的具体产品和产能情况

      2019-05-13 19:49:14 看图中一肖 阅读

      在工业生产环节会大量用到钢管这种管材来进行相应的部件安装以及对应的基础建设安装。对于锅炉行业和相关行业来说,nd钢管是应用在其中一个十分重要的钢管,这种nd钢管的好坏,影响着整个锅炉的工作效率和产能。那究竟nd钢管的外形以及一些要求有哪些呢?下面我们从nd钢管的外形和一些化学成分中进行综合分析:尺寸精度和外nd钢管的几何尺寸主要包括钢管的外径、壁厚、长度、弯曲度、管端面切斜度、坡口角度和钝边,异性钢管的横截面尺寸等。表面质标准中规定了nd钢管的“表面光洁”的要求。
      Steel pipe is widely used in industrial production to install corresponding parts and infrastructure. For the boiler industry and related industries, ND steel pipe is one of the most important steel pipes. The quality of ND steel pipe affects the efficiency and productivity of the whole boiler. What are the shapes and requirements of ND steel pipe? Next, we make a comprehensive analysis from the shape and some chemical components of ND steel pipe: dimensional accuracy and geometric dimensions of ND steel pipe mainly include the outer diameter, wall thickness, length, bending degree, end-face shear slope, groove angle and blunt edge of ND steel pipe, cross-sectional dimension of heterosexual steel pipe, etc. The requirement of "smooth surface" of ND steel pipe is stipulated in the surface quality standard. 因此厂家积极推进措施进行改革。nd钢管行业已开工项目510个,在建项目总投资2699亿元。
      Therefore, manufacturers actively promote measures for reform. The ND steel pipe industry has started 510 projects, with a total investment of 269.9 billion yuan.

      其中,炼铁在建产能3000万吨,正在设计2800万吨,规划建设1700万吨;炼钢在建产能2200万吨,正在设计1000万吨,规划建设1700万吨。
      Among them, 30 million tons of iron-making capacity are under construction, 28 million tons are under design and 17 million tons are planned for construction; 22 million tons of steel-making capacity are under construction, 10 million tons are under design and 17 million tons are planned for construction.

      如果这些项目全部投产,国内炼铁和炼钢总产能将分别达到9.15亿吨和10.2亿吨,折合nd钢管产能达到10亿吨。目前,中国nd钢管产能利用率已经达到国际公认的过剩或者饱和的边缘。
      If all these projects are put into operation, the domestic total capacity of ironmaking and steelmaking will reach 915 million tons and 1.02 billion tons respectively, and the capacity of converted ND steel pipe will reach 1 billion tons. At present, the productivity utilization rate of ND steel pipe in China has reached the internationally recognized edge of surplus or saturation.
