Two-parted ballastblock/counterweight (1) of the known type, round (circular), square as shown on the drawing, hexagonal, octagonal or of any other outer geometrical shape, with imbedded metallic anodes (4) which are to be placed in the immediate vicinity of the metal-bolts (3) which shall be used for attaching and fastening the ballastblocks/counterweights (1) onto a pipeline (2) which pipeline is to be placed on or into the bottom of sea or lake. The imbedded anodes (4) are in this way placed in the longitudinal direction of the bolts (3) and very close to these bolts (3) which bolts the anodes (4) shall protect against corrosion in such a way, that the galvanic field of stress becomes minimal. By forming the anodes (4) as pipes, which are to be imbedded in the ballastblock (1), ensures furthermore, that the long boltholes in the ballastblock (1) becomes straight and formstable. The anodes (4) are on the drawing shown as cylindrical pipes, but they can be made with any other geometrical cross section shape including profiled bars and the like. In the same way these imbedded anodes can be made with any other sectionalizing than that shown on the drawing, for example as bushes or bar-pieces, placed in the long boltholes, eventually directly onto the boltshanks themselves. |
