摘 要: 研究了热力管道布置中的应力计算问题,通过建立π型管补偿和膨胀节补偿两种模型,推导出了适用于其设计工况下膨胀量和受力的公式并运用于实例。 This article concerns related calculations about thermal pipeline stress. By setting up the n-shaped pipeline compensation model and expansion joints compensation model, the essay tries to conclude formulas which are suitable for calculating thermal expansion and joint stress under two design conditions and verify the formulas in real cases.
