Abstract
The present invention provides a pipe for transferring powder material from a reservoir to a container e.g. prior to hot isostatic pressing. The pipe comprises a continuous outer wall and a concentric continuous inner wall enclosed within and spaced from the outer wall. The spacing between the inner and outer walls defines a flow channel extending from an inlet to an outlet. The radial cross sectional area of the outlet is greater than the cross sectional area of the inlet.
Claims20
An apparatus for filling a container with powder material, the apparatus comprising:
- a pipe;
- a reservoir for containing the powder material prior to filling;
- and a container for containing the powder material after filling;
- wherein the pipe comprises a continuous outer wall;
- and a concentric continuous inner wall enclosed within and spaced from the outer wall with both the outer wall and the inner wall joined to the container;
- the reservoir having an outlet for connection to the inlet of the pipe and the container having an inlet in a upper surface for connection to the outlet of the pipe;
- wherein the spacing between the inner and outer walls defines a flow channel extending from a pipe inlet to a pipe outlet, and
- wherein the cross sectional area of the pipe outlet is greater than the cross sectional area of the pipe inlet.
