The utility model belongs to the technical field of expansion joint compensation and provides an anti-condensing and anti-impact expansion joint for a torch pipeline. The anti-condensing and anti-impact expansion joint comprises an inlet pipe (1), an outlet pipe (12), a current guiding cylinder (8), a working corrugated pipe I (7), a working corrugated pipe II (11) and a balancing corrugated pipe (3). An anti-condensing mechanism comprising a steam heat tracing pipe (14) and a fixing band (15) is installed on the lower portions of a balancing corrugated pipe outer tube (5) and a supporting outer tube (10). An anti-impact device is installed between the current guiding cylinder (8) and the outlet pipe (12) or between the outlet pipe (12) and the inlet pipe (1). According to the anti-condensing and anti-impact expansion joint for the torch pipeline, corrosion of a corrugated pipe caused by condensing liquid formed due to a shutdowncan be avoided, and at the same time destructive impact force generated by instant condensing liquid discharging to a bending head located on a pipe turning part and a fixing support can be effectively avoided, and safety and reliability of the expansion joint can be improved.
