Abstract: Hydrostatic testing systems featuring technological advancement, high automation level and fast operation cycle are badly needed to be developed due to the fact that the imported similar systems not only fail to meet the domestic market demand, but also are too expensive.Therefore China Heavy Machinery Research Academe has developed Φ48~178 mm dual-pipe fully-automatic hydrostatic testing system.Elaborated in the paper are the main aspects of the system, including technological parameters, equipment characteristics/composition and functions, and process flows and characteristics, etc.
