The utility model provides a sleeve pipe is sacrificed to marine sea water system anticorrosion cast iron, the utility model discloses sleeve pipe is sacrificed to marine sea water system anticorrosion cast iron, through increasing the sleeve pipe between the sea water pipeline current, and be connected this outer tube and other because of the sealed pipeline of keeping apart of rubber gasket through the jumper wire, thereby realize positive pole and the negative pole of inside iron pipe with outside copper pipe and the tubular one -tenth electrochemical corrosion of continuous sea water, owing to chemical attribute iron phase compares in copper or more active, when electrochemical corrosion takes place, as the sacrificial anode who takes place the corruption, thereby has good anti - corrosion feature under sacrificial anode's prerequisite, protect the sea water pipeline effectively, copper product piping and annex, can regularly can inspect the internal corrosion condition through the vacuum pressure meter o
