Zeng Xiangwei researched the shuttle-type passive control system of pressure pipeline. He provided new technologies for specific media (such as Chemical industry, natural gas), specific environment (such as desert, forest) and operating system (such as water hammer, pulse). The significant technical difficult problem of the petroleum chemical industry, offshore platforms, nuclear power, defense, and other projects were solved. And these control components can work safely and reliably in 20 years. And this control system achieved complete-control or partial-control without outside power source. The shuttle-type passive control system of pressure pipeline expected to extend to the pressure pipeline system
