An apparatus and method for protecting an inner radial surface of a radial member of a turbomachine from corrosion are provided. The method may include shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner. The method may also include heating the radial member to increase a diameter of the inner radial surface of the radial member, and inserting at least a portion of the corrosion-resistant liner into the radial member. The method may further include attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.

The present invention relates to a method for joining at least two metal workpiece parts (2, 8) of a differing metal composition to each other by means of explosion welding, comprising the steps of: •—enclosing an inner workpiece part (2) at least partially with an outer workpiece part (89; •—arranging a mantle of explosive material (14) round the outer workpiece part; and •—detonating the explosive material in order to bring about a metallurgical connection between the two workpiece parts; •—wherein during the detonation of the explosive material the inner workpiece part is substantially wholly filled with and/or is at least partially enclosed by a dilatant non-Newtonian mixture (20). The invention further relates to a workpiece manufactured via this method.

A pyrolysis surface such as a rotating retort is provided by copper sheet supported by a nickel alloy framework. Pyrolysis is used to destroy calorific waste and/or to produce gas therefrom.

A dissimilar metal article may include a first metallic component including a first metal material, a second metallic component comprising a second metal material, and a transition joint provided between and bonding a first metallic component first end surface to a second metallic component first end surface. An additive flow material may be further provided to the dissimilar metal article to strengthen the joint between the first metallic component and the second metallic component.

An arrangement for making a diffusion solder connection between an electrically conductive contact element and a workpiece includes a protective chamber and an acceleration device. The protective chamber has a workpiece position at which at least a portion of the workpiece is arranged. The acceleration device shoots the electrically conductive contact element into the workpiece arranged at the workpiece position.

A method of producing a clad billet includes inserting a solid carbon or low-alloy steel (CS) material into a hollow interior of the slightly larger diameter (CRA) cylinder so that a standoff gap is provided between an outer surface of the (CS) material and the inner diameter of the (CRA) cylinder; providing an explosive material around the (CRA) cylinder; detonating the explosive material to collapse at least the inner diameter of the corrosion resistant alloy cylinder onto the outer surface of the solid carbon or low-alloy steel material and eliminate the standoff gap, creating at least a partial metallurgical bond at an interface with the outer surface and resulting in a composite billet assembly, and extruding the composite billet assembly to reduce its size and form the clad billet having a metallurgical bond between the (CS) material and the (CRA) cylinder.

A pyrolysis surface such as a rotating retort is provided by copper sheet supported by a nickel alloy framework. Pyrolysis is used to destroy calorific waste and/or to produce gas therefrom.

Provided is a method of connecting an austenitic steel pipe with a ferritic steel pipe. The method comprises providing the austenitic steel pipe and the ferritic steel pipe, such that an inner end section of the austenitic steel pipe has an outer diameter smaller than an inner diameter of an outer section of the ferritic steel pipe, inserting the inner end section into the outer end section, such that the inner and outer end sections overlap in a connection region, and welding the inner and outer end sections in the connection region by explosive welding or magnetic pulse welding. Further, a linear quench exchanger and a processing arrangement for processing a process fluid are provided.
