A downhole tubular assembly configured to be mounted as part of a well tubular structure in a borehole of a well having a top, has a well metal tubing configured to be mounted as part of the well tubular structure. A tubular metal receptacle has an inner receptacle diameter larger than the outer diameter of the well metal tubing, and a second part extending from the first part towards the well metal tubing. The tubing length is larger than the receptacle length, and the a wall of the well metal tubing extends inside the tubular metal receptacle along the entire length of the tubular metal receptacle, and the second part of the tubular metal receptacle is fastened to the outer face of the well metal tubing, thereby closing the tubular metal receptacle in one end and defining an annular space between the tubular metal receptacle and the well metal tubing.
