Duerzhong (Deyang) Heavy Equipment Co., Ltd. (hereinafter referred to as Duerzhong) is affiliated to Sinomach Heavy Equipment Group Co., Ltd. and is a major national technical equipment manufacturing base. Over the past 60 years, the double equipment has provided nearly 3 million tons of major technical equipment for domestic and foreign markets, playing a strategic and fundamental role in the national economy and national defense construction.

The double equipment has the ability to provide 900 tons of molten steel, 700 tons of steel ingots, 500 tons of castings, and 400 tons of forgings, and is one of the few enterprises in the world with extreme manufacturing capacity in the field of major technical equipment. The main business of dual equipment covers large-scale complete (set) equipment and large-scale castings and forgings, nuclear power and heavy pressure vessels, and large transmission parts and equipment manufacturing, which can provide systematic equipment manufacturing and services for important industries such as metallurgy, mining, energy, transportation, automobiles, petrochemicals, and aerospace.

In the field of complete equipment manufacturing, Duplex equipment is the core supplier (service) of metallurgical complete equipment and intelligent forging equipment engineering general contracting; In the field of large-scale castings and forgings, Duplex Equipment is an important supplier of a complete set of castings and forgings and key components of the third-generation nuclear power type represented by AP1000, Hualong No. 1 and CAP1400, and is the only top supplier in China that can provide a complete set of castings and forgings for "Three Gorges-level" 700,000 kilowatt hydropower units and mass production of key sets of castings and forgings for million-kilowatt ultra-supercritical thermal power units. In the field of heavy-duty pressure vessels, Duergyi has the ability to manufacture a single oversized and ultra-thick heavy-duty pressure vessel of more than 2,500 tons, and is the backbone supplier of China's large-scale nuclear power and chemical heavy-duty pressure vessels. In the field of large transmission parts, Duergyi is an advantageous enterprise in the manufacturing of large-scale metallurgical and water conservancy transmission parts and equipment, and a major manufacturing base for large-scale wind power speed increasers, wind turbine spindles and wind turbine yaw slurry systems in China.

Stand at a new starting point and embark on a new journey. Guided by the spirit of the 19th National Congress of the Communist Party of China, Duplex Equipment will unswervingly promote the transformation and upgrading of traditional fields, pioneering and innovating in emerging fields, accelerate the pace of product structure adjustment, continuously improve core competitiveness, achieve sustainable and high-quality development of enterprises, and significantly enhance the sense of gain, happiness and belonging of employees, and build Duplex Equipment into a strong cornerstone of national economy and national defense construction and a leading large-scale equipment manufacturing enterprise in China. With inexhaustible creation, it provides a strong development impetus for the heavy flagship to sail away.
