Company Profile

Jiangsu Longye Energy‑Saving Technology Co., Ltd. was founded in 2014. It is a high‑tech enterprise specializing in energy conservation and environmental protection, engaged in the research and development of waste heat recovery systems and equipment for coke oven raw gas, as well as nano‑high‑temperature‑resistant thermal insulation materials and nano‑high‑temperature‑resistant cladding materials. The company has been recognized as a national-level “Little Giant” enterprise distinguished for its specialization, sophistication, distinctiveness, and innovation. Headquartered in the Zhonglou Economic Development Zone of Changzhou City, Longye and its subsidiaries have a registered capital of RMB 31.73 million, with nearly 5,000 square meters of modern office space and a factory complex covering over 40,000 square meters, including 20,000 square meters of production facilities. The company has established core technology infrastructure, such as a nano‑coating processing zone and temperature‑controlled rooms, and is equipped with state‑of‑the‑art laboratory equipment.

Under the leadership of Chairman Meng Xiaodong, the company has adhered to a business philosophy of “people-oriented, technology-driven innovation,” relentlessly pursuing progress and pioneering new frontiers. Since 2010, it has independently developed waste‑heat recovery technology for the rising pipe of coke oven raw gas, creating China’s first industrial‑scale system for recovering waste heat from this source. This breakthrough has effectively addressed three major challenges—graphite deposition, tar buildup, and water leakage—filling a critical gap in domestic coking technology and setting a new benchmark for energy conservation, environmental protection, and reduced energy consumption in the coking industry, thus paving the way toward green coking. The technology was successfully implemented at Fujian Sangang Coking Plant in 2014 and at Wugang Pingmei Coking Plant in 2016. With continuous technological refinement and an ever‑strengthening reputation within the industry, starting in the first half of 2018, the company has steadily emerged as a leading enterprise in the coking sector’s energy‑saving and environmentally friendly initiatives.

Since 2019, leveraging its established expertise in nano‑insulation materials for riser tubes, our company has collaborated with research institutions such as MCC Jiaonai, Southeast University, and Wuhan University of Science and Technology to jointly advance and successfully develop a new generation of high‑temperature‑resistant nano‑insulation materials. After years of intensive R&D efforts integrating industry, academia, and research, this material has emerged as a next‑generation solution for energy conservation and environmental protection in coke ovens. At the same time, we have pursued a diversified growth strategy, deepening our presence in the field of coking‑related energy efficiency and environmental protection. While continuing to refine riser‑tube waste‑heat recovery technology and advancing the development of nano‑high‑temperature insulation materials, we have expanded our business into other areas of coking‑related energy saving, including next‑generation pressure‑equalization systems for coke oven carbonization chambers, dry quenching units, coking wastewater treatment, flue‑gas desulfurization and denitrification, high‑temperature‑resistant gate valves, automatic ignition devices for coke oven riser tubes, and intelligent wireless sensors.

The company boasts a highly qualified technical team characterized by exceptional expertise and strong collaboration, comprising two doctoral degree holders, ten master’s degree holders, ten senior engineers, and twenty engineers. It has also established a comprehensive quality assurance system and obtained certifications for quality management, environmental management, and occupational health and safety management. The company holds ASME “U” certification, Class B boiler manufacturing qualifications, Class A2 pressure vessel design and manufacturing qualifications, as well as GC2‑level design and installation permits for pressure piping. Additionally, it possesses Grade II general contracting qualifications for mechanical and electrical engineering construction and Grade II specialized contracting qualifications for environmental protection engineering. With over 100 national patents to its name, the company has been recognized as a “patent‑intensive product.”

Looking ahead, we will continue to strengthen our research and development capabilities, drive product innovation through technology, and uphold the principles of integrity and trustworthiness. By delivering our finest products and exceptional services, we will provide top‑tier support to coking enterprises across the country, contributing the wisdom and strength of Longye’s team to the transformation, upgrading, and high‑quality development of the coking industry.
