STUDY OF DYNAMIC FRACTURE OF X80 NATURAL GAS PIPELINE

Jixie qiangdu, 2018
A finite element model of the dynamic fracture in a full size gas pipeline is established based on the cohesive zone model. The dynamic crack growth of X80 pipeline steel was simulated using this model and the quantitative relationship between the crack growth rate and the internal pressure predicted is in agreement with the existing semi-empirical ...

Research on Strain of Unequal Wall Thickness Pipeline of the X80 Pipeline under Lateral Load

Journal of Physics: Conference Series
Abstract X80 steel is a material with high strength and good toughness, which is widely used in long-distance natural gas pipelines. Pipelines will have different wall thicknesses, depending on the safety level requirements of different regions.
