Abstract: An extrusion die is disclosed. The extrusion die can include a body member defining a passage therein, and the passage configured to receive heated material at an ingress end of the body member. A mandrel can be disposed within the passage and configured to divert the heated material around the mandrel within the passage as the heated material traverses the passage from the ingress end to an egress end of the body member. The mandrel can define an interior hollow portion that is configured to receive coolant.

Abstract: A universal tool for the weld inspection of tubular objects such as reactor vessels is disclosed. The tool is constructed from an array of transducers mounted in groups for common inspection of a particular weld volume. The individual transducers, as well as the groups, are arranged in a compact assembly for minimizing the overall dimensions of the tool and its corresponding weight. The transducers are arranged in a manner which permits inspection of tubular objects having different radii of curvature and corresponding different diameters with a single tool without the need of having to individually adjust the orientation angles of the transducers.
