Abstract
PURPOSE: To make breaking of a gate after solidification easy and to prevent the off-centering of the working surface of a joint end part in the stage of casting the pipe joint by providing an annular excess metal of a large diameter partially to the working surface on the outside surface in the end part of a rough casting material for the joint and providing the gate to this excess metal.
CONSTITUTION: In the stage of casting a pipe joint having an outside surface 2 for working to be worked with external screw or the like in an end part 1, an annular excess metal 3 of an outside diameter larger than the outside diameter of the surface 2 is provided between the end part having the surface 2 and a riser 4. A gate 5 which is an inflow port for molten metal from the riser 4 is reduced of its section to the smallest size, and is connected to the outside circumferential surface of the excess metal 3. The junction Q-Q thereof is a preset rupture plane. The smallest sectional part of the gate 5 is connected to the outside circumferential surface of the metal 3, by which the breaking of the gate along the rupture plane Q-Q after the solidification of molten metal is made easy. During working of the surface 2, the load is increased circumferentially uniformly by the metal 3, whereby off-centering is prevented.
