Abstract: The present disclosure relates to a bimetallic tube comprising a first metallic tube having an inner diameter and an outer diameter, and a second metallic tube having an inner diameter and an outer diameter, wherein the first metallic tube is arranged within and force-fitted to the second metallic tube and wherein the first metallic tube comprises a zirconium (Zr) based alloy and wherein the second metallic tube comprises an austenitic stainless steel. The present disclosure also relates to a method for manufacturing a bimetallic tube comprising the steps of providing a first metallic tube having an inner diameter and an outer diameter, providing a second metallic tube having an inner diameter and an outer diameter, wherein the outer diameter of the first metallic tube is smaller than the inner diameter of the second tube, inserting the first metallic tube into the second metallic tube, cold-drawing the first and second metallic tubes together, such that the first and second metallic tubes are force-fitted together.

Abstract translation: 本发明涉及一种双金属管，其包括具有内径和外径的第一金属管和具有内径和外径的第二金属管，其中第一金属管是 布置在所述第二金属管内并且强制安装到所述第二金属管，并且其中所述第一金属管包括基于锆（Zr）的合金，并且其中所述第二金属管包括奥氏体不锈钢。 本发明还涉及一种用于制造双金属管的方法，其包括以下步骤：提供具有内径和外径的第一金属管，提供具有内径和外径的第二金属管，其中外径 第一金属管小于第二管的内径，将第一金属管插入第二金属管中，将第一金属管和第二金属管冷拉到一起，使得第一金属管和第二金属管被力配合在一起
