The invention will be described in detail below with reference to the drawings and embodiments.

A pipeline butt joint structure in a heating steam pipeline is shown in figures 1 to 4 and comprises a supporting unit 1 and a connecting unit 2 on the supporting unit; the connecting unit comprises a base 3 and a plurality of connecting pipes 4 extending outwards from the base, a cavity is arranged on the inner side of the base, and the inner cavities of the connecting pipes are simultaneously communicated with the cavity; the connecting pipe comprises a base connecting section 5, a corrugated pipe section 6 and a pipeline connecting section 7; the supporting unit comprises a fixed seat 8 and a supporting column 9 on the fixed seat, the base of the connecting unit is fixed at the tail end of the supporting column, and the fixed seat is provided with a plurality of fixing holes 10. In order to further reduce vibration, a base plate 11 can be arranged at the lower end of the fixing seat, and a shock absorption pad 12 is arranged between the base plate and the fixing seat.

In an optional embodiment, the whole connecting unit is of a three-way structure, three connecting pipes are arranged on a base of the connecting unit, the three connecting pipes are located on the same plane, included angles between every two adjacent connecting pipes are 120 degrees, one heat supply pipeline can be connected from different angles in the same installation plane, the structural arrangement is reasonable, and the connecting operation is easy to implement.
