Abstract: Piping support and dampers is one of important parts of pipe system， and it affects the security of pipe system significantly， but there are complex kinds of NPP， huge quantity and difficult to manage. In order to enforce the supervisory ability， to exten the service lifetime of pipe， analysis the fail mode and summarize the operation experience of piping supports， this paper designs and realizes a management information platform of the piping support and dampers based on B/S mode for a domestic NPP. It’s proved that the system is easy and convenient for in-service inspection.

Key words: NPP, piping support and dampers, B/S mode, management information platform
