PURPOSE:To enable the replacement of a sealing plug by a method wherein the sealing plug is inserted into a hole formed at a horizontal coupling surface of turbine casing and then the sealing plug is crossed at a right angle with a vertical coupling surface. CONSTITUTION:A hole for sealing plug is formed on a horizontal coupling surface, a sealing plug 5 is inserted at the end surface D of the discharging chamber and arranged in such a way as it may be crossed with a vertical coupling surface. Then, inserts 6, 7 are fixed to the discharging chambers 3, 4 by a welding at 8. In case of a replacement of the sealing plug 5, at first the inserts 6, 7 are removed and the sealing plug is replaced. |
