Based in the Jiangsu province of China, the Hang Ji Group has established a significant industrial footprint as a dedicated manufacturer of marine ancillary equipment and fluid control systems. Tracing its operational history back to the founding of Nantong Marine Machinery Group Co., Ltd. in 1973, the organization has evolved over more than five decades from a local machinery workshop into a comprehensive enterprise capable of designing, developing, and manufacturing complex marine modules.
The company operates from a substantial facility in the Nantong Economic Development Zone, covering approximately 62,500 square meters. Within this campus, a large portion is dedicated to specialized production workshops equipped with over 300 sets of advanced manufacturing machinery, including vertical and horizontal machining centers. This infrastructure supports the group’s transition toward intelligent manufacturing and high-precision engineering, allowing it to maintain control over the entire production lifecycle—from raw material processing to final assembly and testing.
In the maritime and offshore sectors, Hang Ji Group functions as a critical link in the equipment supply chain, focusing on systems that manage essential vessel fluids and mechanics. Its core engineering competencies lie in the production of diverse filtration systems, valve remote control devices, and hydraulic support units. These components are vital for the reliable operation of shipboard machinery, ensuring that fuel, oil, and water systems function correctly under the demanding conditions of ocean transit. Beyond basic mechanical components, the company has expanded its scope to include specialized marine modules and environmental protection solutions, such as ultraviolet sterilization units for water treatment.
The group’s commitment to industrial standards is evidenced by its adherence to rigorous quality management protocols. It maintains certifications across multiple international standards, including ISO9001 for quality, ISO14001 for environmental management, and ISO45001 for occupational health and safety. Furthermore, its ability to meet military-grade specifications (GJB9001C) underlines the reliability of its engineering. Recognized domestically as a high-tech enterprise and a specialized "Little Giant" in the manufacturing sector, Hang Ji Group serves a broad spectrum of clients, delivering technical solutions that span not only commercial shipping and shipbuilding but also extend into aviation, electric power, and petrochemical industries.
