Engineering machinery is a general term for construction machinery used in engineering construction. Widely used in construction, water conservancy, electricity, roads, mines, ports and national defense and other engineering fields, a wide variety, including mining machinery, shovel transport machinery, engineering lifting machinery, etc., with the national economic development, all kinds of construction projects significantly increased, the demand for construction machinery is also increasing.

Marine engineering refers to a new construction, reconstruction or expansion project located on the seaway side of the coastline for the purpose of developing, utilizing, protecting and restoring Marine resources. It mainly includes the construction of offshore platforms and artificial islands, such as oil and gas exploration and exploitation platforms. Since the second half of the 20th century, the world's population and economy have expanded rapidly, and the demand for energy has also increased sharply. With the exploitation of oil and gas in the continental shelf waters, as well as the continuous expansion of Marine resources development and space utilization scale, the Marine engineering corresponding to it has become one of the rapidly developing projects in the past 30 years.

In recent years, with the rapid growth of the national economy, electricity consumption has soared, and the power industry has developed rapidly. The state vigorously promotes the "west power transmission to the East" and "North power transmission to the south" projects, especially the successful practice of UHVDC transmission projects, which has strongly promoted the rapid development of the power transmission industry. China's electric power transmission industry shows a good development trend, with the continuous increase of grid investment, the demand for electric power transmission will also increase, transmission line industry development prospects are broad.

From the brilliant light of the Bronze Age to the stirring sound of the industrial revolution, the development process of metallurgical mines embodies the endless sweat and wisdom of human beings. We have mined precious minerals from the depths of the Earth and turned them into a powerful driving force for society to move forward. In the face of the challenges and opportunities brought by globalization, metallurgical mines are developing and reforming at an unprecedented speed, and green, low-carbon and sustainable production mode has become a new development trend.

Wind energy is one of the pollution-free energy sources, and as a clean and renewable energy source, it is increasingly valued by countries around the world. Wind power has advantages such as cleanliness, good environmental benefits, renewability, short infrastructure cycle, and flexible installed capacity. Wind power is an important field for the development of renewable energy, an important force in promoting energy technology progress and industrial upgrading, and an important measure to promote energy structure adjustment. The development prospects of China's new energy generation industry such as wind power are very broad, and it is expected to maintain high-speed development for a long time in the future。

In the past decade, China's construction industry has experienced sustained and rapid development. The construction industry is a pillar industry of the national economy and has made significant contributions to economic growth. With the regulation of the real estate market, competition among construction companies has intensified, leading to a reduction in profit margins. Despite some challenges, with the acceleration of urbanization and the promotion of the the Belt and Road Initiative, the construction industry still has broad prospects for development. There are still many countries in the world that are in the stage of development and construction. With the development of social economy and the acceleration of urban construction, the construction industry will continue to maintain a clear development trend in the coming period。

China's oil and gas engineering is in the stage of long-term construction and large-scale development. A large number of oil and gas pipe fittings have been put into use. The quality and performance of pipe fittings are closely related to the operation safety and service life of the project.

New energy vehicles are expected to become machines that can once again change the world. While bringing us fast transportation, energy conservation and emission reduction have become the top priority of the global automotive industry. Developing the new energy vehicle industry has become a strategic direction for China's automotive industry。
