Abstract
PURPOSE: To prepare a pipe having projections on both its ends or in the middle of it by means of centrifugal casting by a method wherein the pipe having a projection or projections such as a flange etc. on its outer surface is prepared separately from the pipe body and this pipe with a projection or projections is fitted by force.
CONSTITUTION: A pipe body 1 and a flange pipe 3 is mounted mutually in concentricity with the ram body 8a and the supporting body 8b of a hydraulic jack 8. On the pipe body 1 a marking off line 9 is drawn at the final pressed position of the flange pipe 3. An inserting hole 1a of the pipe body 1 is fitted by force into the flange pipe 3 through the pressure of the hydraulic jack 8. This force fit can be carried out fully by the pressure of the hydraulic jack 8 at a cold temperature because there is a determined fit standard between the inserting hole 1a and the flange pipe 3 and chambered parts 6, 7 are prepared. Then, if the and face of the flange pipe 3 and the outer surface of the pipe body 1 are welded to each other, a flange pipe having flanges 2, 5 on both its ends are formed. Thereby, centrifugal casting process can be adopted in order to prepare flange pipes, and long pipes also be manufactured.
