摘要

高压油气输送管道的关键部件往往是承受复杂载荷的环焊缝。我们的研究和本文的目的是介绍我们在环焊缝上施加循环内压和叠加外弯曲应力的全尺寸管道疲劳和破裂试验，从而吸引研究结果的重要性和适用性。建立了一种独特的测试系统来研究管道环焊缝在同时载荷作用下的性能。测试使用摄像机记录、内部压力与破裂时间函数和失效压力值进行评估。

Full-Scale Tests of Pipeline Girth Welds Under Complex Cyclic Internal Pressure and Static Bending Loading Conditions

The critical elements of high-pressure hydrocarbon transporting pipelines are often the girth welds, which are subjected to complex loads. The aims of our research and this paper are to introduce our full-scale pipeline fatigue and burst tests applying cyclic internal pressure and superimposed external bending stress on girth welds, furthermore, attracting the importance and the applicability of the investigation results. A unique testing system was built to study the behaviour of pipeline girth welds under simultaneous loads. The tests were evaluated using video camera recordings, internal pressure vs. burst time functions and failure pressure values.
