The invention relates to a cooling device, and in particular relates to a cooling device for pipe production. The cooling device for the pipe production comprises a cooling box, wherein a pipe inlet and a pipe outlet are correspondingly formed in two sides of the cooling box. The cooling device for the pipe production is characterized by further comprising a water cooling mechanism, a circulating pipe and a circulating pump; a plurality of separating plates are vertically arranged in the cooling box; a pipe hole is coaxially formed in each separating plate; openings are alternatively arranged in top and bottom between every two adjacent separating plates; two ends of the circulating pipe correspondingly communicate with the top parts of two sides of the cooling box; the water cooling mechanism and the circulating pump sequentially communicate with the circulating pipe. The cooling device for the pipe production is applicable to the pipe cooling; cooling water enters from a low-temperature part, in the cooling box, of a pipe, and gradually flows to a high-temperature part of the pipe, and the heat of the pipe is absorbed through the cooling water, so that the temperature of the cooling water fits the temperature of the high-temperature part of the pipe, and gradual cooling is achieved, and as a result, the brittleness, caused by meeting cold suddenly, of the pipe, can be avoided.
