Abstract (en)
A device for applying an internal coating in tubes comprises a nozzle (16), a mixing casing (12) arranged in connection with the nozzle and configured to receive at least two coating material components. Driving means intended to be located outside the tube to be coated and configured to drive an elongated flexible member (18) to rotate also causes said nozzle to rotate by being connected to said flexible member while throwing said coating material substantially radially outwards towards inner walls of the tube. Mixing members (28, 29) inside a mixing compartment (24) of the mixing casing are brought to carry out a stirring movement inside said compartment for mixing the coating material components arriving thereto to a substantially homogenous mixture, which is drained to said nozzle.
