Abstract: In order to solve the problems as staying with steel pipe hydrostatic testing,a Visual Studio 2013 C#platform-based system for hydrostatic testing and information storage & analysis is developed.Briefed here in the article are the general hardware/software architecture,and the logic flows of the C# function blocks,including data acquisition for pipe hydrostatic testing,real-time curve display,download of equipment parameters,dumping the hydrostatic testing data into the local industrial control data base,pipe number correction and data dual backup,etc.Focused on are the suitability of Prodave 6.2 and the programming difficulties such as communication processing,and history curve quality report,etc.The actual operation result of the said system demonstrates that the system runs steadily,and meets the site service requirements;and the pipe statistic testing data can be automatically acquired,and stored with dual backup so as to provide data support for the traceability for quality of the steel pipe hydrostatic testing.
