The utility model provides a can carry top grafting pipe anti -corrosion performance's metal expansion joint, includes bellows, takeover and draft tube, the takeover is connected respectively at the bellows both ends, the draft tube setting in the bellows, the takeover is equipped with the annular with the link of bellows, the seam tube -shape stainless steel lining board of annular department, the tip and the stainless steel lining board seam of bellows. The utility model discloses set up corrosion -resistant stainless steel lining board, stainless steel lining board and takeover argon arc welding connect, and stainless steel lining board constitutes anticorrosive protective screen to taking over, effectively delays the etch rate of corrosive medium to taking over. In addition, at weldingbead position coating one deck anticorrosive paint, avoid the medium to erode the welding bead, lead to the welding bead position to corrode in early days. The aforesaid is improved when keeping thegood compensation performa
