Company Profile

Jiangsu Longye Energy-Saving Technology Co., Ltd. is an enterprise born in response to the call for ecological civilization. Located in the Zhonglou Economic Development Zone of Changzhou City, Jiangsu Province, the company boasts a modern office space of over 3,000 square meters and a factory campus spanning more than 40,000 square meters, including a 20,000-square-meter production workshop. The company has established core‑technology nanocoating processing facilities, temperature‑controlled rooms, and other essential infrastructure, and is equipped with state-of-the-art laboratory equipment.

Since 2010, we have independently developed waste‑heat recovery technology for the rising pipe of coke oven raw gas, creating China’s first industrial‑scale unit for recovering waste heat from coke oven raw gas. This breakthrough has addressed three major challenges—graphite deposition, tar buildup, and water leakage—thereby filling a critical gap in domestic coking technology. In 2019, building on nano‑insulation materials for the rising pipe, our company joined forces with MCC Coking Refractories (Dalian) Engineering Technology Co., Ltd., Southeast University, University of Electronic Science and Technology of China, and other research institutions to jointly advance and successfully develop a new generation of high‑temperature‑resistant nano‑insulation materials. After five years of collaborative R&D involving industry, academia, and research, and following extensive industrial validation, this material has emerged as a next‑generation solution for energy conservation and environmental protection in coke ovens.

Our company has currently developed a new type of nano‑based, high‑temperature‑resistant thermal insulation material, which is widely used in industries such as petroleum, chemical engineering, metallurgy, coking, and asphalt processing at elevated temperatures, achieving energy‑saving efficiencies of…15%–50%, marking a new milestone for enterprises in energy conservation, environmental protection, reducing energy consumption, and achieving green carbon neutrality.

The company currently boasts a robust R&D team, comprising two PhDs, eight master’s degree holders, ten senior engineers, fifteen engineers, and more. With its strong technical expertise, the company was awarded the national-level “Little Giant” designation for specialized, refined, distinctive, and innovative enterprises in 2021.

We will boldly embrace innovation, build on our strengths through sustained effort, and press forward as leaders in the energy‑saving and environmental‑protection sector.
