Abstract (en)

[origin: EP0348720A2] The method serves for removing layers adhering to the surfaces of container walls by means of explosive charges with refrigeration of the container wall. After refrigeration of the container wall has occurred, numerous explosive cords 2 are arranged on the outer surface of the wall part 1 which cords, after detonation, bring about the removal of the layer lying on the inside of the wall 1 of the container.
