Abstract

A transition component for connecting components of a chemical or process engineering plant, wherein the transition component has a first material piece made from a first material and second material piece made from a second material, wherein the first material and the second material cannot be connected to each other by fusion welding, the first material piece and the second material piece forming a hollow body, the transition component having a radially interior inner side and a radially exterior outer side, the first material piece being connected to the second material piece by at least one intermediate material layer and the transition component having at least one insulation layer, wherein the insulation layer extends at least in part over the inner side and/or the outer side of the transition component, and a core-in-shell heat exchanger and a cold box having the transition component.

First claim

The invention claimed is:

1. A transition component for connecting components of a chemical or process engineering apparatus, wherein the transition component comprises:
a first material piece made from a first material and a second material piece made from a second material, wherein the first material and the second material cannot be connected to each other by fusion welding,
the first material piece and the second material piece form a hollow body, and the transition component has a radially interior inner side and a radially exterior outer side,
the first material piece is connected to the second material piece by at least one intermediate material layer, and
the transition component has at least one insulation layer, wherein the insulation layer is a refractory lining and arranged on the inner side of the transition component and extends at least partially over the inner side of the transition component, and wherein the first material is steel or stainless steel, and the second material is aluminum or an aluminum alloy.

2. The transition component according to claim 1 , wherein the at least one insulation layer is arranged in such a way that the at least one insulation layer covers the first material piece, the at least one intermediate material layer, and the second material piece.

3. The transition component according to claim 1 , wherein the refractory lining comprises an aluminum oxide ceramic, concrete, a honeycomb structure made from plastic, insulating foam, and/or styrene, or a mixture thereof.

4. The transition component according to claim 1 , wherein the at least one intermediate material layer is a metallic layer.

5. The transition component according to claim 1 , wherein the at least one intermediate material layer is a silver layer, a nickel layer, or a nickel-titanium layer.

6. The transition component according to claim 1 , wherein the transition component comprises a further insulation layer is arranged on the outer side of the transition component wherein said further insulation layer is a sheath.

7. The transition component according to claim 6 , wherein
the first material piece is connected to a first piping made from the first material, and the second material piece is connected to a second piping made from the second material, wherein the sheath further covers a section of the first piping and/or a section of the second piping, and
wherein the refractory lining comprises an aluminum oxide ceramic, concrete, a honeycomb structure made from plastic, insulating foam, and/or styrene, or a mixture thereof.

8. The transition component according to claim 1 , wherein the at least one intermediate material layer is applied to the first and/or second material piece by explosive cladding.

9. The transition component according to claim 1 , wherein the first material piece and the second material piece each have a relatively thin section and a relatively thick section, wherein the intermediate material layer is arranged between the thick section of the first material piece and the thick section of the second material piece.

10. A core-in-shell heat exchanger comprising an outer container, a plate heat exchanger surrounded by the outer container, a supply line via which fluid can be introduced into the plate heat exchanger, and a discharge line via which fluid can be removed from the plate heat exchanger, wherein at least one transition component is arranged in the supply line and/or in the discharge line, said transition component comprising:
a first material piece made from a first material and a second material piece made from a second material, wherein the first material and the second material cannot be connected to each other by fusion welding,
the first material piece and the second material piece form a hollow body, and the transition component has a radially interior inner side and a radially exterior outer side,
the first material piece is connected to the second material piece by at least one intermediate material layer, and
the transition component has at least one insulation layer, wherein the insulation layer extends at least partially over the inner side and/or the outer side of the transition component, and wherein the first material is steel or stainless steel, and the second material is aluminum or an aluminum alloy.

11. The core-in-shell heat exchanger according to claim 10 , wherein the insulation layer is arranged on the outer side of the transition component and is a sheath.

12. The core-in-shell heat exchanger according to claim 11 , in which the first material piece is connected to a first piping made from the first material, and the second material piece is connected to a second piping made from the second material, wherein the sheath further covers a section of the first piping and/or a section of the second piping.

13. The core-in-shell heat exchanger according to claim 11 , wherein the sheath comprises metal and/or plastic and/or ceramic and/or concrete.

14. The core-in-shell heat exchanger according to claim 11 , in which the first material piece is connected to a first piping made from the first material, and the second material piece is connected to a second piping made from the second material, wherein the sheath further covers a section of the first piping and a section of the second piping.

15. The core-in-shell heat exchanger according to claim 10 , wherein the insulation layer is arranged on the inner side of the transition component and is a refractory lining.

16. The core-in-shell heat exchanger according to claim 10 , wherein the plate heat exchanger is formed from the second material, and the supply line and/or the discharge line has a first piping made from the first material and a second piping made from the second material, wherein the second piping is connected to the plate heat exchanger, and wherein the first piping is connected to the second piping via the at least one transition component.

17. A cold box containing at least one process engineering apparatus, wherein piping within the at least one process engineering apparatus and/or within a supply line to and/or discharge line from the cold box has at least one transition component, said transition component comprising:
a first material piece made from a first material and a second material piece made from a second material, wherein the first material and the second material cannot be connected to each other by fusion welding,
