The invention belongs to the technical field of connecting pipe arms, and particularly relates to a six-degree-of-freedom connecting pipe arm. The six-degree-of-freedom connecting pipe arm comprises afirst universal hinge type bellow expansion joint, a second universal hinge type bellow expansion joint and a pull rod constraint type bellow expansion joint with a steering connector and a straight-through connector, one end of the first universal hinge type bellow expansion joint is connected with a device connector, the other end of the first universal hinge type bellow expansion joint is connected with the second universal hinge type bellow expansion joint through a straight pipe, the other end of the second universal hinge type bellow expansion joint is connected with the steering connector of the pull rod constraint type bellow expansion joint, the straight-through connector of the pull rod constraint type bellow expansion joint is connected with a bent-pipe-shaped adjusting pipe, and the other end of the bent-pipe-shaped adjusting pipe is connected with an outer pipe connector. The six-degree-of-freedom connecting pipe arm is suitable for energy transmission of pipelines with various calibers and various flows; the connecting arrangement structure is simple, six-degree-of-freedom flexible compensation can be achieved in a single-plane mode and in a double-plane mode, and on-site installation and positioning of the connecting pipe arm are easy; and the six-degree-of-freedom connecting pipe arm is tolerant to the displacement cycle fatigue of a device system and is more suitable for long-term continuous fluid conveying working condition scenes.
