Abstract (en)
[origin: EP2309527A2] The device has an end cover (3) comprising a part (C) that is offset with respect to an end surface (10) of a cylindrical body (1) in a direction of outside of the body, after the part is brazed onto the body and in a direction of central axis of the body. The part is followed by another part (D) extending inside the body. The parts extend around an axis of the cover. The cover is shaped in such a way that a circular peripheral part of the cover exerts a compressive stress on one third of the end surface of the body after brazing. Thickness of the cover is smaller than 2.5 mm.
