Recently, the double-station production process of DN2000mm×8000mm extra large diameter centrifugal ductile iron pipe independently developed by Xinxing Casting Pipe was successfully achieved. The successful development of this process has greatly improved production efficiency and enhanced the core competitiveness of the company.
Prior to this, the twin-station production process of the emerging cast pipe was limited to DN1600mm or less. For the large-diameter cast pipe of DN1800mm and above, only the single-station production process can be used, the production efficiency is low, and the production capacity is greatly limited. Since the second half of 2005, the company's third cast pipe department has become a research team. After a lot of research and experimentation, it has finally broken through the restrictions and achieved success in the heat load test on March 21 this year. Increased by more than 60%, the cost is also greatly reduced, and the economic and social benefits are significant.
As a leading enterprise in the production of cast pipes, Xinxing Cast Pipe has consistently adhered to scientific and technological innovation and formed a complete set of core technologies with independent intellectual property rights. In the process of casting pipe technology and product development, it has won the National Invention Patent Gold Award, the Second Prize of National Science and Technology Progress, the Ministry of Machinery Science and Technology Progress Special Award, the Hebei Province Governor Special Award, and the Hebei Province Science and Technology Progress Special Award. Xinxing Casting Pipe also presided over the national standard of GB/T13295-2003 "Nodular cast iron pipe, fittings and accessories for water and gas pipelines" and the industry standard of CJ/T183-2003 "Steel-plastic composite pressure pipe" construction department. At the same time, as the sole representative of China's cast pipe industry, Xinxing Cast Pipe has continuously participated in the revision of the international standard for centrifugal ductile cast pipe, breaking the long-term control of developed countries to hinder the situation of developing countries, and erecting the banner of Chinese cast pipe in the world. .
At present, the company's production scale reaches 1.2 million tons, and the domestic market share is about 40%. 30% of its products are exported to 58 countries and regions in the world, and its comprehensive technical strength ranks first in China and world leader.
