Patent ID: 7900969

Claim:
A connector for disposition between a reaction pipe of a reaction furnace and a cooling pipe of a reaction gas cooler, wherein the cooling pipe is embodied as a double pipe having an inner pipe and an outer pipe, wherein the inner pipe is disposed in an extension of the reaction pipe and the outer pipe surrounds the inner pipe such as to form an intermediate cooling space between the inner pipe and the outer pipe, and wherein the connector comprises: a supply chamber adapted to be connected to the intermediate cooling space for supplying a coolant thereto; a transition piece adapted to be connected to the reaction pipe, said transition piece having an end portion, remote from the reaction pipe, with a fork-shaped configuration and composed of an inner portion and an outer portion, wherein a layer of heat-insulating material is adapted to be disposed between said inner portion and said outer portion, and wherein said outer portion of said transition piece is secured to a base of said supply chamber coaxially relative to a longitudinal axis of the cooling pipe; half shells, wherein said supply chamber, said transition piece and said half shells are embodied as a prefabricated unit; and an inner tube section welded into said supply chamber, wherein said inner tube section extends out of said supply chamber and is aligned with said inner portion of said transition piece, wherein said inner tube section has a thickness, inner diameter and outer diameter that correspond to a thickness, inner diameter and outer diameter of the inner pipe, wherein a thickness, inner diameter and outer diameter of said half shells correspond to a thickness, inner diameter and outer diameter of the outer pipe, and wherein an axial length of said half shells is greater than the length of that part of said inner tube section that extends out of said supply chamber.
