摘要
运用材料力学理论,给出了端焊式套管换热器的计算方法,包括考虑热应力时内管、外管的轴向应力计算。根据应力性质,确定了轴向应力的强度及稳定性控制条件,并通过有限元算例验证了理论公式的正确性。
Axial stress calculation under the influence of heat expansion between inner and outer pipe was introduced. Allowable stress for extension and compression were also discussed. A FEM example was con- ducted to test the theoretical formula.
