The petroleum industry is an industrial sector that extracts and refines petroleum (including natural oil, shale oil, and natural gas). Composed of units involved in oilfield geological exploration, oilfield development, oil extraction, transportation, refining and processing. Petroleum is the "blood" of industry and an important industrial energy source.

The chemical industry is a general term for enterprises and units engaged in chemical production and development, covering three major categories: petrochemicals, basic chemicals, and chemical fibers. The basic chemical industry is further divided into nine categories, including fertilizers, organic products, inorganic products, and chlor alkali. This industry has penetrated into various fields and is an indispensable and important component of the national economy. Its development is of great significance to human economic and social development.

The power industry is an industrial sector that converts primary energy sources such as coal, oil, natural gas, nuclear fuel, hydropower, ocean energy, wind energy, solar energy, biomass energy, etc. into electrical energy through power generation facilities, and then supplies it to users as energy through transmission, transformation, and distribution systems. It is an important basic industry of the national economy, directly related to national economic security, social stability, and people's daily lives.

The pharmaceutical industry mainly covers the R&D, production and sales of chemical raw materials and preparations, Chinese medicinal materials, Chinese herbal pieces, traditional Chinese patent medicines and simple preparations, antibiotics, biological products, biochemical drugs, radioactive drugs, etc., which plays a vital role in ensuring human health and improving the quality of life.

The new energy industry refers to all related work carried out by units and enterprises engaged in the development of new energy. New energy refers to renewable energy that can be systematically developed and utilized based on new technologies, including solar energy, wind energy, hydro energy, biomass energy, geothermal energy, ocean energy, nuclear energy, etc. The new energy industry has advantages such as abundant resources, environmental friendliness, and sustainable utilization, and is an important direction for global energy transformation. It is of great significance for addressing climate change, ensuring energy security, and promoting sustainable economic development.

With the increasingly demanding demands and tight production schedules of projects such as oil and gas, engineering experience in these fields has become extremely important. The engineering site for energy supply and storage not only considers the high temperature, high pressure, and control performance of automatic control valves, but also meets the requirements of various harsh environments, which has become a necessary condition for valves. The experienced Lidian technical team has adopted a series of reliable and open solution combinations to meet any challenge. The solution portfolio covers a wide range and can help you reduce risks throughout the entire project implementation process, enabling you to immediately enter the application phase.

The papermaking industry is a fundamental raw material industry closely related to the national economy and social life. It includes the pulp manufacturing industry that uses wood, reed, bagasse, rice straw, wheat straw, cotton straw, hemp straw, cotton and other raw materials to make pulp. It is one of China's the Four Great Inventions.

The metallurgical industry needs new solutions that can help improve the safety environment and enhance customers' infrastructure. The corrosion and wear problems during the processing cause pipeline aging and valve wear, requiring frequent maintenance and treatment, resulting in costly downtime. Despite limited production capacity, operators are under immense pressure to meet the growing industry demand for faster and more efficient supply of metals and minerals. Our advanced mining technology includes regulating valves, electronic electric butterfly valves, and ball valves, which can help achieve process automation and extend factory production cycles.
