The company holds relevant special equipment qualifications in China for pressure vessel design and manufacturing and pressure piping components, and operates quality, environmental and occupational health and safety management systems.

HUAYI has a multidisciplinary team covering engineering, manufacturing, welding, inspection and testing. The company's manufacturing facilities support pressure vessel fabrication, skid assembly, piping integration, welding, inspection and equipment testing for project-specific gas equipment.

Quality control is incorporated throughout engineering and manufacturing, from material and component inspection to fabrication, assembly and testing. Technical documentation and inspection records can be prepared according to applicable project requirements.

Products, Applications & Project Support

HUAYI supplies equipment and integrated systems for natural gas transmission and distribution, LNG and CNG gas supply, industrial gas applications, gas treatment, odorization and biogas upgrading.

Our engineering approach is based on project-specific operating conditions rather than standard equipment selection alone. Depending on the application, equipment can be configured according to gas flow rate, inlet and outlet pressure, gas composition, temperature, process requirements, control philosophy and site conditions.

HUAYI supports customers throughout the project process, including technical clarification, equipment selection, engineering coordination, manufacturing, inspection, documentation and delivery. For international projects, technical documents and project-specific information can be prepared according to customer and contract requirements.

We welcome cooperation with gas companies, engineering contractors, EPC companies, distributors and industrial users seeking gas equipment and project-specific solutions.
