New challenges in the steel pipe industry

“Double carbon” is now and in the future for a long time the steel industry must answer the question of The Times. Among 31 Chinese manufacturing categories, iron and steel industry has the largest carbon emission, accounting for about 15% of the country. The task of emission reduction of welded steel pipe is arduous, and we face great challenges. How to reduce carbon scientifically tests the wisdom of the industry.

Carbon reduction is a new proposition and a new challenge in front of the industry. In order to achieve the goal of “double carbon”, it is necessary to reduce the output and improve the proportion of short-process electric furnace steel. In 2060, China’s output should be controlled to 600 million tons, and the proportion of electric furnace steel should be increased to 40%, which can reduce carbon emissions by 1.3 billion tons annually. Only by reengineering process and energy structure can we reach the goal of carbon neutrality.

Under the background of double carbon, the traditional development mode of iron and steel industry can no longer meet the needs of low carbon development, and must be deeply reformed. At present, there are many researches on the future development path of the steel industry, but the steel industry of cold rolled steel pipe must realize carbon neutrality through the innovation of energy structure, process structure and material technology. The innovation of energy structure can solve the carbon emission problem from the source, the innovation of process structure can reduce the coal consumption from the source, and the innovation of material technology can reduce the carbon dioxide emission intensity from the whole life cycle.

It is widely believed in the industry that the application of hydrogen energy is an important path for the iron and steel industry to achieve the goal of “double carbon”. Whether from the perspective of energy structure innovation or process structure innovation, the application of hydrogen metallurgy technology will bring revolutionary changes to the traditional iron and steel metallurgy technology. Therefore, there is a huge demand for hydrogen to achieve the emission reduction target of pre galvanized steel pipe. But the new generation of hydrogen metallurgy technology is just starting, and there is a long way to go in the future.

As an important force in the world iron and steel industry, China has made substantial steps in reducing carbon emission. The understanding of carbon peak carbon neutrality in iron and steel enterprises has been strengthened continuously; A number of steel companies have made clear the goal of carbon neutrality; The carbon peak implementation plan and carbon neutral technology roadmap for the steel industry have taken shape.

But our steel industry also faces some realistic problems. For example, extensive steel consumption habits, resulting in some unnecessary steel demand of square steel pipe; There is a large amount of scrap steel resources, but it is restricted by quality and logistics. Enterprise concentration is not enough, technology research and development resources are not concentrated, talent shortage, innovation is not high; Insufficient protection of intellectual property rights.
