我国钢管行业70年发展历程

将我国钢管行业70年(1949-2019年)的发展历程分为5个阶段,回顾我国钢管行业在每个阶段的发展情况,包括机组建设、钢管产量和进出口量及品种等情况。我国钢管产量从新中国成立之初的0.4万t/年,增长到2018年的7 320万t/年;2000-2015年我国钢管行业发展快速,在此期间钢管产量达到9 801.8万t的峰值,在世界钢管总产量中占比达到65%;2008年,钢管出口量达到989.5万t的峰值;目前我国钢管品种、规格、质量取得了显著进步,绝大多数钢管品种的自给率已达到100%。

70 Years History of Domestic Steel Tube-making Industry

The 70 years history of the domestic steel tube-making industry(1949—2019)is divided into five stages.The development situation of each stage is reviewed,including mill constructions,steel tube outputs,import and export volumes and product types,etc. The annual output has been increased from 4 000 tons in the time of founding of P.R.China to 73.20 million tons in 2018. During the 2000 —2015 period,the industry had been developed very fast,and the steel tube annual output had reached the peak,i.e.,98.018 million tons,accounting for 65% of world total output. And the yearly steel tube export volume had also reached the peak of 9.895 million tons in 2008. Up to now,the domestic steel tube-making industry has made great progresses in terms of product types,sizes and quality,and the self-sufficient rates of most of the steel tbe types have been up to 100%.
