The invention provides a manufacturing method of a guide pipe, and belongs to the technical field of machining. The manufacturing method comprises the steps that a plurality of guide vane prefabricated parts are machined; coaxially welding a middle flange outside the middle part of the annular inner plate to form an inner plate assembly; a suspension connecting flange, the inner plate assembly and a guide pipe shaft are coaxially positioned and assembled together, so that the suspension connecting flange is located at the first end of the inner plate, and the guide pipe shaft is sleeved with the suspension connecting flange and the inner plate assembly; for each guide vane prefabricated part, the guide vane prefabricated part is positioned and installed between the inner plate assembly and the guide pipe shaft through the clamping section, and the two non-clamping sections are attached to the inner wall of the inner plate and the outer wall of the guide pipe shaft correspondingly; the guide vane prefabricated part is welded to the inner plate and the guide pipe shaft respectively, and a welding part is obtained; and all the clamping sections in the welding piece are machined, and the guide pipe is obtained. The processing precision can be improved.
