Universal super-strength aluminum oxide ceramic tube

Two ends of a ceramic tube body are opened, the interior of the ceramic tube body is communicated, a plurality of annular multifunctional cutting grooves are formed in a tube body on the outer surface of the ceramic tube body, groove walls on two sides of each annular multifunctional cutting groove are symmetrical inclined sections, and groove bottom surfaces on the inner sides of the annular multifunctional cutting grooves are convex arc surfaces. A frosted layer is coated on the pipe surface of the inner pipe body of the ceramic pipe body, and expansion notches are respectively formed in the cross extension ends of the centers of the inner diameters of pipe orifices at two ends of the ceramic pipe body. By means of the mode, the aluminum oxide ceramic tube is generally used in the special field of aluminum oxide ceramic tubes and has ultrahigh strength, the annular multifunctional cutting grooves formed in the tube body on the outer surface of the ceramic tube body can be used for winding heating coils and
