On December 9–10, the ASME Joint Inspection Team, led by senior expert Mr. Niu Can, reviewed our company’s third application for renewal of the “U” stamp certificate.

On October 7, the 1.8-million-ton-per-year continuous heavy-duty unit for the Sinochem (Guangdong) Refining and Chemical Integration Project—manufactured by Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd.—was successfully lifted into place, marking the start of its final installation phase. This unit is a coiled-tube material exchange heat exchanger, designed as a replacement for bulky plate-type heat exchangers. Each device weighs nearly 300 tons and boasts a heat exchange area exceeding 10,000 square meters, underscoring a significant leap in China’s capability to manufacture large-scale refining and chemical integration equipment.

The kickoff meeting for the key equipment—including the tail gas treatment reactor, esterification pre-reactor, and feed heat exchanger (coil-type heat exchanger)—of the 400,000-ton-per-year syngas-to-ethylene glycol project at China Energy Group Shenhua Yulin Energy & Chemical Co., Ltd., was successfully held on April 14–15, 2019, at Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd.

The second-phase research project on the development of a highly efficient coiled-tube reactor, jointly conducted by Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd. and the Institute of Process Engineering, Chinese Academy of Sciences, recently concluded successfully. The study established a comprehensive design methodology tailored to various operating principles, significantly enhancing the heat-transfer capability of the coiled-tube reactor—by more than 50% compared to conventional shell-and-tube fixed-bed reactors—thereby greatly boosting enterprises' production efficiency.

Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd. was established in 2007 and is a high-tech enterprise dedicated to the research, development, design, and manufacturing of energy and chemical equipment—recognized as a national-level "Little Giant" specializing in niche expertise and innovation.
