The invention discloses application of a sleeve type heat compensator in the field of buckling prevention of a submarine pipeline. The compensator comprises an outer casing, an outer sleeve pressure pipe, an inner pipe, compression bolts, rolling bearings, a sealing rubber layer and the like. An axial limiting structure is arranged in the pipes, so that one-way movement of the inner pipe relativeto the outer pipe is ensured. Compared with a traditional sleeve type compensator, the risk of damage caused by reciprocating movement of the pipeline and sealing materials under the repeated effect of the temperature and pressure is lowered; meanwhile, through the axial limiting structure, the initial tensile stress generated by the pipeline can counteract part of the pressure stress generated under the combined effect of the temperature and pressure, so that overall buckling of the pipeline is prevented, the buckling prevention effect based on initial tensile stress generated by embedding apre-buckling pipeline in the prior art is achieved, and the problem of difficult embedding in a deep sea when the initial tensile force is applied in the prior art is solved; and the construction costis reduced, and the safety of pipeline work is ensured.
