Corrosion protection device and metal plant are prevented to positive pole wound form in sea water

The utility model provides a corrosion protection device and metal plant are prevented to positive pole wound form in sea water. The corrosion protection device is prevented to the positive pole wound form in the sea water, includes: two seal installation terminals, line type anode body and insulating tubes, be provided with external cable on the seal installation terminal, a plurality of through -holes have been seted up to the insulating tube, line type anode body inserts in the insulating tube, line type anode body's both ends are sealed and are inserted the correspondence in the seal installation terminal and with external cable connects. The insulating tube can along the winding of the outside profile of metalwork on the metalwork because line type anode body is connected in the seal installation terminal with external cable, can be connected external power source's positive pole with line type anode body electricity through external cable, and the negative pole of power can be connected with the shell of the metalwork of treating the protection, the shell that makes the metalwork waiting to protect has appropriate current potential and prevents corrosion treatment, metal plant anti -corrosion performance in the realization improvement sea water with the realization.
