Abstract
A method is disclosed for removing a seal that is fixed in a groove of a component. A highly pressurised jet of liquid is aimed at the seal or between the seal to free it from the groove. The method is particularly suitable for freeing a sealing strip in a rotor or in a housing of a turbine-type machine, and is considerably less time-consuming and expensive than the twisting-off method that has been used up until now.
