Abstract

In the process of operation, oil and gas pipelines are prone to corrosion due to the influence of transportation medium and the external environment, which leads to safety accidents. In order to study the evaluation of residual strength of corrosion defects in natural gas pipelines, the calculation methods and application scope of each evaluation standard are described in this paper. Taking a long-distance natural gas pipeline as an object, a finite element model of pipeline corrosion defects was established by ABAQUS, and the effects of defect length, depth, width, and pipe diameter thickness ratio on the residual strength of pipelines with corrosion defects were studied. Based on the failure pressure of pipelines with different corrosion defect sizes calculated by finite element numerical simulation, the applicability of each standard method was analyzed, and the residual strength evaluation method suitable for this kind of gas transmission pipeline was given.
