Labyrinth-Piston Oxygen Compressors: Three Chinese-Built 5,000 Nm³/h Skids Ship to Vietnam
Three 5,000 Nm³/h skid-mounted labyrinth-piston oxygen compressor packages built by Hangyang have passed factory inspection and shipped to a Vietnamese project, using a factory-integrated design that cuts site installation work.
Lead
Three large skid-mounted labyrinth-piston oxygen compressor packages, rated at 5,000 Nm³/h, completed factory inspection on 30 September and have shipped to a project in Vietnam, the China General Machinery Industry Association reported.
Facts
The shipment. The three packages were built by Hangyang Compressor Co. (杭州杭氧压缩机有限公司) for a project of an international group in Vietnam; they passed factory inspection on 30 September 2026 and were dispatched. (Source: the China General Machinery Industry Association, 2026-10-08.)
The machine. The labyrinth-piston design is described as the maker's mainstay oxygen-compressor product; labyrinth sealing addresses the high-purity oxygen duty, where oil contact is prohibited and sealing integrity drives safety and running life. The skid-mounted execution completes assembly and testing in the factory, so site work reduces to connecting pipework. (Source: the same; trade-press background.)
The maker's year. The coverage places the shipment within a broader run of overseas deliveries by the Hangyang group in 2026, including air-separation units and expansion turbines to projects in Southeast Asia, Africa and West Asia. (Source: trade-press coverage of the same shipment.)
