Method for improving efficiency of stress compensator of underground oil and gas conveying pipeline



The invention provides a method for improving efficiency of a stress compensator of an underground oil and gas conveying pipeline. The method has the advantages that the problems of low efficiency of the high-temperature underground oil and gas conveying pipeline and great increase of amount of compensators only at the turning part of the pipeline in the prior art are solved; artificial deformation spaces are formed at the underground pipeline compensator and the pipe bending part; the efficiency of the compensator and the self secondary stress-resistant capability of a pipeline are improved; the setting amount of compensators is greatly reduced, one part of investment on the compensators is saved, and the manufacturing, transportation and construction cycle is shortened.
