Seamless steel tube industry in China looking for thermal power and nuclear power tube upgrade direction, it is imperative that Chinese steel pipe industry breakthrough a batch of national construction need, lead the future development of key steel tubes and technology;In 2020, established a strong capacity for independent innovation and sustainable healthy development, production, study and research, closely integrated with pipe industry system.Key varieties at the same time, the industry can meet the needs of the national economy and national defense construction, some high-end pipe products reach the world advanced level, steel pipe products upgrading has made significant effect, transformation and upgrading of seamless steel tube enterprises make substantive progress, realize the steel pipe industry from quantity to the varieties, quality and benefit of strategic transformation.At present, steel industry should focus on developing supercritical and ultra supercritical thermal power unit with large diameter heat resistant, resistant to high pressure tube, nuclear power unit with high-performance ferritic and austenitic stainless steel, manganese and chrome molybdenum alloy steel pipe and so on, further optimize and improve technology, stable quality, overcome nuclear power steel pipe specifications, and the difficulty of small batch, more one thousand ways to meet the nuclear power development in our country many varieties, many specifications, high-quality requirements.To improve the technical level of ultra supercritical thermal power units in our country, realize the 600 ℃ ~ 700 ℃ ultra-supercritical coal-fired power generation technology for thermal power unit manufacture, high-end boiler tube products research and development direction of the upgrade should be a higher level of high-end heat pipe.Although domestic seamless steel tube enterprises can produce to meet domestic demand for more than 95% of the varieties of high pressure boiler tube, but as a result of supercritical and ultra supercritical and update the unit puts forward higher requirements for materials and specifications, to fully replace imported, domestic enterprises in the research and development ability and product quality stability, there is still room to improve.At present, our country has been successfully mass production CPR1000 AP1000 / EPR million kilowatt evaporator PWR 690 alloy u-shaped heat transfer tube.In April 2014, a new generation of 2014 alloy u-shaped heat transfer tube of the first batch of products delivery of demonstrative project of national key CAP1400 nuclear power unit, this shows that the nuclear power technology and key equipment manufacturing capacity in China as the international advanced level.For thermal power unit, implements the key of ultra supercritical thermal power unit boiler tube from scratch, from there to the whole, from the whole to advanced historic leap, filled the domestic blank, to break the foreign monopoly;The domestic market share of domestic high pressure boiler tube from less than 30% to 90%, and implemented a large number of exports, completely changed the pattern of boiler tube markets around the world.By the end of 2013, our country has built 600 ℃ steam parameter ultra-supercritical thermal power unit is about 122.4 million kw (141 units), these units are only accounted for 14.2% of existing thermal power unit in China, but have accounted for 80% of the world's similar machine.Although our country has become a coal-fired power generation technology leading countries, but used in the ultra supercritical thermal power unit pipe research and development and manufacturing, there is still a gap with advanced countries in the world.Optimize the energy structure in our country and realize the basic act of national strategy of energy conservation and emissions reduction targets is the key and priority to the development of high parameter high-capacity ultra-supercritical thermal power units and million kilowatt nuclear power units.
