摘要:
概述了日本高压输气管线抗震安全性设计的基本原理，以及高应变X80管线钢（X80-HSLP）所要求的应变性能，并通过X80-HSLP弯曲变形实例，研究了管线钢管在弯曲变形时压缩侧的应变能力和拉伸侧环形焊缝的应变能力。假如这种高应变X80钢管的外径、壁厚、设计系数分别为762mm，15.6mm和0.40，那么可以测定其临界压缩应变为2.14%，大约是常规X80钢管的1.5倍。这种优良的应变能力可以降低管线敷设成本，保证敷设在地震和寒冷地区管线的整体抗震安全性。
Abstract:
This article summarized the basic concept of anti-seismic design of high-pressure gas pipelines as well as the strain capacity required by high-strain X80 grade pipeline steel(X80-HSLP).The studies on the strain capacities of pipeline steel on the compression side and the circumferential welds on the tension side while bending deformation were carried out through some cases of X80-HSLP bending deformation.Assuming the outside diameter,the wall thickness and the design factor of the high-strain X80 grade pipeline steel as 762mm,156mm,and 0.4,so critical compressive strain will be 2.14%,which is about 1.5 times larger than that of the conventional X80 grade steel pipe.The excellent strain capacity can reduce construction costs and ensure antiseismic integrity of pipelines buried in seismic and cold areas.
