Since the conditions for the hydrostatic test of the pipe are different from the conditions for the use of the plastic pipe, in general, the conditions for the hydrostatic test are relatively close to the failure temperature and failure pressure of the plastic pipe, and if the pressure ratio to which the pipe is subjected is large, the temperature will increase. Since the temperature has a great influence on the hydrostatic test results, the temperature deviation of the thermostatic waterbath must be controlled within a standard range, the average temperature difference of the aqueous medium in the incubator being 1℃and the maximum deviation being 2℃according to the GB/T6111 related regulations. In the prior art, the constant temperature water tank adopts a transverse door type, the temperature fluctuation in the tank is large during the door opening period, and the pipe in the same constant temperature water tank is damaged, and the leakage can influence the test of other pipes around, so that the existing constant temperature water tank cannot meet the requirements of small temperature fluctuation and small deviation.
