Abstract
A method and apparatus for removing a canister 12 from a component 18 by forming an opening 30 in the canister wall thickness 14, 16 and introducing a pressurised fluid into the opening 14, 16 causing hydrostatic pressure build up between an internal canister surface 14 and the component 18, leading to the removal of the canister 12. This method and apparatus obviates the need to expend significant machining or chemical processing to remove the canister 12.
Claims14
A method of separating a hipping (Hot Isostatic Pressing) canister from a HIPped component, the method comprising steps of:
- providing the hipping canister with a metallic canister wall having a first surface and an opposite second surface, wherein an aperture opens to the first surface and contains a blocking member, the second surface having an attachment feature arranged to attach a fluid supply conduit to the attachment feature;
- removing the blocking member to create an opening extending through a wall of the hipping canister;
- and
- separating the first surface from the HIPped component by supplying a fluid under pressure through the opening.
A canister for a hot isostatic press (HIP) process comprising a metallic canister wall having a first surface and an opposite second surface, wherein:
- an aperture opens to the first surface and contains a blocking member, and
- the second surface has an attachment member arranged to attach a fluid supply conduit to the attachment member such that fluid can be supplied through the aperture when the blocking member is removed from the aperture.
