Company profile
JINHONG GAS CO., LTD. was founded in 1999 as a gas-solutions provider integrating research and development, production, sales, logistics, and services. The company is headquartered in Panyang Industry Park, Xiangcheng District, Suzhou, China. JINHONG GAS has been listed on the SSE STAR Market since June 2020 under stock code 688106. Its gas portfolio is organized around specialty gases, bulk gases, and LNG, with additional industrial, medical, electronic, and mixed-gas products across the wider product range. The company reports 90 subsidiaries and cumulative exports to more than 50 overseas countries and regions. Gas-production facilities in Singapore, Vietnam, and Thailand support international operations and turnkey gas solutions outside China. Global-operation support includes technical assistance, export-compliance work, and support related to cross-border investment. The company has an R&D center, a CNAS laboratory, and a cylinder-testing center for gas-development, analysis, and cylinder-related work. A national enterprise technology center and the CNAS-accredited laboratory support electronic-gas development and analytical testing. The company reports 318 patents, including 73 invention patents, in connection with its gas technology and R&D activities. Its laboratory capabilities include gas chromatography, ICP-MS, moisture analysis, infrared analysis, and cavity-spectroscopy methods for high-purity gas characterization. Research and development work includes electronic gases, gas-filling solutions, analytical methods, and participation in standards-related technical projects. The company lists recognition including national high-tech enterprise status, intellectual-property-related recognition, semiconductor-industry innovation recognition, and patent awards. Its product history includes more than 20 years of gas operations and a range of more than 100 gas varieties. The business serves semiconductor, electronics, photovoltaics, medical and life-science, metal-processing, manufacturing, food, energy, environmental, and other industrial sectors. The company combines production capacity with logistics, on-site service, engineering, quality control, and total-gas-management functions so gas supply can be managed from gas production and storage through the point of use.
Exhibits
JINHONG GAS supplies gas from small laboratory volumes through continuous large-scale industrial production using cylinders, portable Dewars, large cryogenic storage tanks, and on-site generation systems. On-site generation options include nitrogen, oxygen, and hydrogen, while specialty mixture gases can be formulated to customer requirements. The company states more than 15 years of on-site gas-supply experience and configures the supply mode according to actual user gas demand. Gas-supply solutions include storage and delivery using cylinders, tanks, and bulk-gas methods with refill and delivery support. Gas Cabinets and Manifolds are provided for storage and distribution of hazardous, high-purity, corrosive, and multi-cylinder gases. Cabinet and manifold functions include leak detection, automatic changeover, emergency shutdown, remote monitoring, and multiple protective layers. Selection guidance, installation, commissioning, and long-term maintenance are available for gas cabinets and manifolds used in semiconductor, photovoltaic, chemical, new-energy, and other demanding operations. Engineering services run from demand assessment and solution design through equipment installation, pipeline construction, and system commissioning. The engineering scope includes high-purity gas pipelines, centralized supply systems, cryogenic storage, and pressure-reduction systems. Semiconductor, electronics, and photovoltaic projects can combine high-purity piping, storage, installation, and commissioning in one engineered gas-delivery system. Total Gas Management, or TGMS, is designed for medium and large gas users and can place professional teams on site to manage the gas supply chain. TGMS functions include real-time inventory monitoring, consumption optimization, routine equipment maintenance, emergency replenishment, and safety and compliance management. Cylinder-treatment services include internal polishing, surface treatment, periodic inspection, and disposal of scrapped cylinders according to carrier-gas requirements. Quality-management certifications listed by the company include ISO 9001, ISO 14001, OHSAS 18001, ISO 22000, and FSSC 22000, along with GMP compliance for medical applications. Quality control starts with supplier qualification and incoming inspection and continues with online production monitoring using gas chromatography and oxygen or moisture analyzers. Critical process parameters use automatic interlock protection, while finished gas is subjected to multiple rounds of sampling or full inspection and can receive third-party reverification. Cylinder-interior treatment such as grinding and passivation is used to reduce secondary contamination during filling, storage, and transportation. An ERP traceability system uses a one-bottle-one-code approach from raw-material warehousing and batch analysis through final logistics delivery. Gas purity ranges from industrial grade through 5N, 6N, and 7N-plus, with impurity control reaching ppb and in some specifications ppt levels. Each batch can be tested through the CNAS-accredited laboratory with third-party reports, and electronic specialty gases and mixtures are described as complying with SEMI standards. The company uses certified personnel, emergency drills, preventive-maintenance inspections, intelligent monitoring, and operational support as parts of its gas-safety system. Its gas-supply platform also combines automated production lines with working standards intended to maintain safety from gas filling through distribution. For semiconductor and electronics manufacturing, the company supplies ultra-high-purity specialty gases for wafer fabrication, display panels, and photovoltaic production. The semiconductor application set includes gases used for diffusion, lithography, deposition, etching, doping, and process-chamber cleaning. Display manufacturing uses include doping, deposition, etching, and chamber-related processing, while photovoltaic applications include thin-film, polysilicon, and III-V solar-cell production. LED manufacturing is another electronics market listed for high-purity and specialty gas supply. Medical and life-science supply includes pharmacopoeia-compliant medical gases and cryogenic-storage solutions for biological samples. Metal processing uses precision-mixed welding gases and high-pressure laser-cutting auxiliary gases for welding and cutting operations. Food-related supply includes food-grade gases, while energy and chemical applications include work connected with carbon capture, utilization, and storage. Additional market solutions cover glass manufacturing, environmental applications, food packaging, general manufacturing, and other process industries with tailored gas requirements. The company also provides training programs for gas-industry users as part of its customized supply solutions. On-site gas supply is selected according to consumption patterns so different generation or storage methods can be used to optimize the user gas-supply arrangement. The R&D center, CNAS laboratory, and cylinder-testing center support these services with independent development, gas analysis, and cylinder-related verification capabilities. Named high-purity products in the technical portfolio include ammonia, hydrogen, nitrous oxide, carbon dioxide, silane mixtures, C4F8, argon, and nitrogen. These gases are applied across LED, photovoltaic, LCD, and integrated-circuit manufacturing where process-specific purity and impurity control are required. Analytical instrumentation used for gas verification includes GC-based analysis, ICP-MS, moisture analysis, infrared analysis, and cavity ring-down spectroscopy. The company participates in electronic-gas standards and technical programs through its R&D and testing organization. Its wider service portfolio also includes dangerous-goods transportation, total gas and chemical management, gas-system design and installation, on-site generation, and third-party cylinder inspection. For international customers, turnkey supply can combine production from the Singapore, Vietnam, and Thailand facilities with technical support, export compliance, engineering, and localized service. The resulting semiconductor-facing offer covers high-purity gases, storage and distribution hardware, gas engineering, on-site generation, total-gas management, cylinder treatment, quality assurance, traceability, training, and international supply support.
