ABSTRACT:
A gas collection pipe (1) carrying hot gas establishes the connection between the combustion chambers (9) of a gas turbine plant and the flow channel (13) of the gas turbine. The gas collection pipe (1) has two inlet pipe connections (2), which open via an elbow (3) axially into a gas ring channel (4), which is joined to the flow channel (13). Cooling air is guided on the outside along the elbow (3). A plurality of ribs (8) are arranged at spaced locations from one another on the outside on the gas collection pipe (1) in the area of the elbow (3) on the side facing away from the flow channel (13).
