Five Key Custom Chemical Equipment Manufacturers in China 2026

CALIFORNIA, CA, UNITED STATES, October 22, 2026 /CourierPR/ -- Custom chemical equipment continues to play a crucial role in various industries, including chemical processing, pharmaceutical production, environmental protection, and advanced materials manufacturing. As process requirements become more specialized, manufacturers are increasingly evaluated on their ability to engineer non-standard equipment, accommodate demanding operating conditions, and integrate individual units into coordinated process systems.

According to SNS Insider, the global chemical processing equipment market was valued at USD 64.80 billion in 2025 and is projected to reach USD 68.82 billion in 2026, with further growth forecast through 2035. The chemicals and petrochemicals segment accounted for 41.6% of revenue in 2025. Meanwhile, the separation machinery market is expected to reach USD 109 billion in 2026 and grow to USD 203.1 billion by 2035.

This industry review profiles five China-based companies associated with custom chemical equipment: Jiangsu Xuyang Chemical Equipment Co., Ltd., Weihai Chemical Machinery Co., Ltd., Zhejiang Linox Machinery Co., Ltd., Liaoyang Shenzhou Machinery Equipment Co., Ltd., and Wuxi Chemical Equipment Co., Ltd. The review considers product scope, engineering requirements, material selection, system integration, and technical documentation.

Jiangsu Xuyang Chemical Equipment Co., Ltd., established in 2009 in Jingjiang Economic and Technological Development Zone, Jiangsu Province, is a China-based chemical equipment manufacturer. The company reports a manufacturing facility of approximately 10,000 m², around 110 employees, a seven-engineer R&D team, an annual production capacity of 1,000 units, and a registered capital of RMB 81 million. The company also reports cooperation with more than 300 customers and exports to Japan, South Korea, and Southeast Asia.

Xuyang's product portfolio covers reactors, pressure vessels, heat-transfer equipment, evaporation and crystallization systems, corrosion-resistant equipment, and integrated process packages. The company's reactor portfolio includes stainless-steel and carbon-steel models, electric-heating reactors, high-pressure reactors, internal- and external-coil configurations, intelligent reactors, and specialized reactors made from materials such as titanium, zirconium, and Hastelloy. Depending on the process design, these products may be specified as a Stainless Steel Reactor, Industrial Chemical Reactor, or Custom Pressure Vessel. For more demanding applications, the company's reported product range also includes high-pressure and special-material configurations.

The heat-transfer range includes shell-and-tube, floating-head, U-tube, spiral-plate, finned-tube, and titanium heat exchangers, together with condensers, coolers, and reboilers. A Shell and Tube Heat Exchanger can be configured for different process duties, with reported material options including SS304, SS316L, carbon steel, titanium, and Hastelloy, depending on the component and design. The range also encompasses Industrial Heat Exchanger applications where heat recovery, cooling, or condensation must be coordinated with the process equipment.

For storage and pressure service, Xuyang lists vertical and horizontal storage tanks, horizontal pressure vessels, non-standard vessels, and customised process tanks. Heating and cooling options include jackets, half-pipe coils, and external coils. These configurations can be considered for Storage Tank and Stainless Steel Storage Tank applications, subject to the required medium, design pressure, temperature, and fabrication specifications.

The company's filtration and separation portfolio includes candle filters for solid-liquid separation, catalyst recovery, and fine chemical processing. Its membrane separation and filtration equipment cover membrane processes such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), and membrane bioreactors (MBR). These systems support applications involving separation, purification, and concentration of liquid streams, alongside broader Industrial Filtration Equipment requirements.

Xuyang also reports evaporation and crystallization solutions, including mechanical vapor recompression (MVR), thermal vapor recompression (TVR), multi-effect evaporation, and waste-heat recovery. For projects requiring coordinated equipment delivery, the company offers skid-mounted systems that can integrate reactors, tanks, heat exchangers, filters, pumps, piping, instrumentation, and PLC or DCS controls on a common frame. This approach is relevant to Skid Mounted Process Equipment projects where pre-assembly can help coordinate equipment interfaces before shipment.

Qualifications, engineering, and manufacturing at Xuyang include an A2-level Special Equipment Design and Manufacturing License, alongside ISO 9001 quality management, ISO 14001 environmental management, and ISO 45001 occupational health and safety management certifications. The company also reports an ASME U Stamp for pressure-vessel work. The applicable scope and current validity of these credentials should be confirmed against the relevant documents before procurement.

Its stated engineering activities include industry-university-research cooperation with Nanjing Tech University, China University of Petroleum, and Soochow University. The company also reports the establishment of Nanjing Xuyang High-End Equipment Research Co., Ltd. and cooperation with Nanjing SuZhi Intelligent Equipment Research Institute on intelligent-reactor technology.

Weihai Chemical Machinery Co., Ltd., established in 1975, specializes in the design and manufacture of pressure vessels and high-pressure reaction equipment. Its product portfolio includes stirred reactors, magnetic-drive reactors, towers, columns, heat exchangers, pilot-plant equipment, and explosive-clad plates. According to the company's published information, its equipment serves petrochemical, fine chemical, pharmaceutical, energy, and new-material applications.
