The “first set” of localized equipment

Why is it so important?

Since the 18th National Congress of the Communist Party of China, my country has made remarkable achievements in the development of major technical equipment, but the problems of weak industrial foundation and weak innovation ability have not been fundamentally solved.

Continuing to promote the demonstration and application of the first (set) of major technical equipment in the energy field, and speed up the innovation of major energy technical equipment, can effectively ensure the security of the industrial chain and supply chain of key technical equipment, and play a very important role in the country!

The so-called first (set) of major technical equipment refers to equipment products that have achieved major technological breakthroughs in China, possess intellectual property rights, and have not yet achieved market performance. The identification of the first set of major technical equipment for localization requires strict review and evaluation from the following aspects :

 

• Technological sophistication and complexity

• Marketing prospects

• Intellectual property situation

• social and economic benefits

• Manufacturing enterprise qualification

• R&D and production capacity

• Quality and after-sales guarantee ability

Therefore, the enterprises that can be shortlisted for the first (set) of major technical equipment (projects) in the energy field released by the National Energy Administration are all enterprises with strong independent research and development capabilities in various fields, and have been engaged in innovative research and development and manufacturing of major technical equipment for a long time.

As a strategic and leading enterprise in the industry, over the past 70 years, Shengu has almost taken over the research and development of the “first set” of localized large-scale key core power equipment in the country. For China’s petroleum, chemical, natural gas, electric power, metallurgy, environmental protection, national defense and other important projects involving the national economy and people’s livelihood, it has provided thousands of sets of domestic major technical equipment , and achieved an annual output of 1.5 million tons of ethylene, 20 million tons of oil refining, and 100,000 empty space. Breakthrough in localization of nearly 200 major equipment such as compressors for long-distance natural gas pipelines, large wind tunnels, high-thrust reciprocators for hydrogenation, and main pumps, secondary and tertiary pumps for nuclear power plants ! Behind each “first set” is the hard work and sweat of Shengu’s “achieving customers, focusing on quality, continuous innovation, and pursuing excellence”.
