PROBLEM TO BE SOLVED: To provide a steel pipe joint, a steel pipe junction structure, and a steel pipe junction method such that reduce processing costs can be reduced and steel pipes can be rotated without being applied with turning force from outside when the steel pipes are joined together.SOLUTION: A junction end of one steel pipe 1A to be joined is provided with a female-side steel pipe joint 10, and a junction end of the other steel pipe 1B is provided with a male-side steel pipe joint 20. A male cylinder 21 of the male-side steel pipe joint 20 is inserted into a female cylinder 11 of the female-side steel pipe joint 10 while a male-side inclined surface 24 is inserted by being slid on a female-side inclined surface 14 so as to rotate the male cylinder 21 on its axis, and a male-side engagement part 23 is thereby engaged with a circumferentially adjacent female-side engagement part 13 so as to join the steel pipes together with the steel pipe joints 10, 20. |
