Abstract: A hot gas-carrying gas collection pipe (1) of a gas turbine, which is arranged between the combustion chamber and the turbine blades. The gas collection pipe (1) has two inlet openings (2) for receiving the hot gas. The outlet comprises the flanges (5, 6), which are connected to the turbine. The material of the gas collection pipe (1) is a high-temperature- and corrosion-resistant base metal (9) with a high-temperature corrosion and oxidation coating (4) applied to both the inside and the outside of the base metal (9). In the area of the inner cone (13), an HTCO coating (4) is applied to the base metal (9) on one side and a thermal barrier coating (8) is applied on the opposite side.
