The utility model discloses a guide bracket for a cryogenic pipeline in the field of petrochemical engineering. The cryogenic pipeline comprises a heat insulation layer, a cold insulation layer and asteel hoop which are sequentially arranged outside the cryogenic pipeline from inside to outside, the steel hoop comprises an upper steel hoop body and a lower steel hoop body which are detachably connected. A rib plate for supporting the support is arranged at the bottom of the lower steel hoop, the bottom of the rib plate is connected with the bottom plate in a T-shaped mode, guide blocks are symmetrically arranged at the two ends of the bottom plate and fixedly connected with the bottom plate through guide plates, and the distance between each guide block and the bottom plate ranges from 1mm to 3 mm. The guide bracket for the cryogenic pipeline can accurately control the transverse displacement of the cryogenic pipeline and meet the guide requirement of a cold insulation pipeline.
