PROBLEM TO BE SOLVED: To improve the reliability of the backlash prevention of an anticorrosive core.SOLUTION: A flange type pipe joint 10 includes: a flange body 20; and an anticorrosive core 22. The flange body 20 includes: an outer cylinder part 30; a core fixing part 32; and a flange collar part 34. The core fixing part 32 fixes the anticorrosive core 22. The flange collar part 34 is provided at one end part 40 of the outer cylinder part 30. The anticorrosive core 22 includes: an inner cylinder part; an anti-loosening part; and a seal collar part. The inner cylinder part is inserted into the outer cylinder part 30. The anti-loosening part is connected with the flange body 20 at the core fixing part 32. The anti-loosening part prevents the inner cylinder part from being removed from the outer cylinder part 30. The seal collar part is provided at one end part of the inner cylinder part. When the anti-loosening part is connected with the flange body 20 at the core fixing part 32, the seal collar part comes in contact with the flange collar part 34 to deflect. |
