【摘要】 现有确定埋地长输管道壁厚的诸方法,均未考虑温度变化对环向应力的影响。本文着重讨论了温差的影响,且提出以内压和温差所引起的环向应力作为选择壁厚的控制应力。根据有关强度理论,导出了确定管壁厚度的方程。更多还原

【Abstract】 This paper mainly discusses the effect of temperature differential on the circumferential stress, proposes that the circumferential stress caused by the internal pressure and temperature differential can be considered to be the control stress for choosing the wall thickness, and de- rives equations to determine the wall thickness of the pipelines.更多还原
