The invention discloses a movable corrosion test-bed which comprises a trolley. Multiple reaction vessels are arranged on the trolley. A support for supporting an inlet pipe, an outlet pipe and a pipeline is welded on the trolley. The inlet pipe and the outlet pipe are respectively connected to a thermostatic water tank. An air storage tank is connected to one end of the pipeline through manual vacuum valves. A tail gas recovery tank, a refrigeration container and a vacuum pump are respectively connected to the other end of the pipeline through manual vacuum valves. A water jacket is welded outside a barrel of each reaction vessel; a water inlet tap at the lower part of the water jacket is connected to the inlet pipe; a water outlet tap at the upper part of the water jacket is connected to the outlet pipe; a barrel flange is formed on the upper part of the reaction vessel; and a bulge formed on an upper cover flange and a groove formed in the barrel flange are sealingly connected through a rubber blanket. The movable corrosion test-bed has a simple structure, is convenient to operate and saves occupation of land. The reaction vessels are isolated from each other, can be respectively used for feeding materials and pumping materials and can be applied in multiple testing systems. Thus, mutual cross reactions among the reaction vessels are avoided.
