A cleaning element for cleaning the interior of heat exchanger tubes by being carried along by a cooling water stream and automatically squeezed through the tubes by the cooling water stream, includes a sphere foamed in a closed mold, the sphere being formed of an open-cell sponge rubber core and an open-pore water-permeable skin integral with the core.

Cleaning elements for inside cleaning of the tubes of tube-type heat

Cleaning member for cleaning the interior of heat exchanger tubes by rotating, including a sponge rubber element being adapted to suit the diameter of the heat exchanger tube, and abrasive elements connected to the sponge rubber body, the abrasive elements being in the form of bristles each having a bristle shaft, and a bristle base molded into the sponge rubber ball anchoring the bristles.

Cleaning member for cleaning the interior of heat exchanger tubes

Cleaning member for cleaning the interior of heat exchanger tubes by rotating, including a sponge rubber body having a given diameter, an adhesive film disposed on the sponge rubber body, and an abrasive layer formed of granular abrasive elements being fastened on the sponge rubber body by the adhesive film, the granular abrasive elements having an average linear dimension being smaller than the given diameter of the sponge rubber body, and the granular abrasive elements being disposed in a loose packing causing the abrasive layer to be deformable together with the sponge rubber body.
