| titleOfInvention | Method for production of an acid proof, seemless pressure vessel |
| abstract | The invention relates to a method for production of a cylindrical acid proof, seamless pressure vessel having hemispherical top and bottom by powder moulding in an HIP (Hot Isostatic Pressing) process. Sheet metal moulds are produced constituting an internal shell (1), lower part of an external shell (3), upper part of an external shell (4) with filling spout (5) with corresponding top and bottom. Distance pins (2) decide the wall thickness and are mounted outward from the internal shell which is led down into the lower part of external shell (3) whereafter shell part (4) with filling spout (5) closes the volume be-tween the internal and external shells which is then filled with powder through the filling spout (5). The pressure vessel is placed in an HIP-process container for vacuuming, sealing, supply of high-pressure inert gas such as argon, at high temperature such as 1000 °C, for processing together with the distance pins (2) to a compact and homogenous material. |
