Abstract
A method and arrangement for repairing a leaking point in a plate pack of a plate heat exchanger (1), in which a space between adjacent plate pairs of the plate pack (4), with which the leaking point is in connection, is closed by arranging a separate strip (9) or sealing tape (10) into the space between the plate pairs on the whole length of the outer perimeter of the plate pack.
Claims10
A method for repairing a leaking point in a plate pack of a plate heat exchanger, which plate pack comprises heat exchange plates having openings and arranged on top of each other, the perimeters of which define the outer surface of the plate pack and which plates are attached to each other as plate pairs in such a manner that
- the inner parts of the plate pairs are arranged in connection with each other through flow channels formed by the openings of the heat exchange plates, whereby a primary circuit of the heat exchanger is formed to the inner parts of the plate pairs, and
- the spaces between the plate pairs are arranged in connection with each other through the outer surface of the plate pack, whereby plate spaces of a secondary circuit are in the spaces between adjacent plate pairs,
- wherein the space between adjacent plate pairs of a plate pack, with which the leaking point is in connection, is closed by arranging a separate strip or sealing tape into the space between the plate pairs on the whole length of the outer perimeter of the plate pack.
