摘要：
The present invention addresses the problem of providing a high pressure tube bundle heat-exchanger with components that are pressure resistant to pressures up to 300 bar. The present invention provides an elbow (1) with a circular cross-section having a deviation angle of 180 degrees for a tube bundle heat exchanger for large product pressures, such that an outlet of the tube bundle is fluidically connected to an inlet of an adjacent downstream tube bundle and, an inlet of the tube bundle is fluidically connected to an outlet of an adjacent, upstream tube bundle via the elbow； the elbow having a first flange (2) on each inlet (E) and a second flange (3) on each outlet (A) of the elbow (1). The elbow (1) consists of two elbow halves (1.1, 1.2) which are respectively made of a single piece such that each elbow half (1.1, 1.2) comprises a joining point (V) on the end facing away from the flange (2, 3) and that the elbow halves (1.1, 1.2) are connected together on the associated connection point (V) and such that the extension of the passage cross-section of each elbow half (1.1, 1.2) is formed by rotationally symmetrical through-openings, from which at least one of the flanges (2, 3) and at least one of the associated connecting points (V) extends in the respective coaxial arrangement on the rotational axes (X1.1, Y1.1； X1.2, Y1.2), and that the first and the second rotational axes (X1.1, Y1.1) of the through openings of the first elbow halves (1,1) and the third and the fourth rotational axes (X1.2, Y1.2) of the through openings of the second elbow halves (1.2) extend on a common plane, which represents a meridian plane (M) for each flange (2, 3).
