The invention discloses a ceramic pipe, which comprises a pipe sleeve and a chassis which is integrally molded with the pipe sleeve. A first pipe and a second pipe which are communicated with each other are arranged in the pipe sleeve and the chassis. The ceramic pipe has the advantages that the structure is simple and unique; and since segmented pipes with different inner diameters and the inner diameter of an outlet is larger than the inner diameter of an inlet, the internal pressure of the pipe is reduced and the service life of the ceramic pipe is prolonged.
