  • On the basis of mechanical parameters test, the fatigue strength analysis and static load strength analysis of the Titanium circularly-grooved tube were made. In addition, the numerical calculation of the stress concentrated parts was done by the finite element method. From the analysis and calculation, the conclusions were as follows: at the condition of the condenser was normally operating, the Titanium circularly-grooved tube could fulfill the requirements of the fatigue strength and static load strength; The thermal stress was relatively large in the resulted stresses from various loads. For a condenser more safe, it is necessary to equip the expanding node at the end of condenser shell to decrease the thermal stress; Titanium circularly-grooved tube applied in the condenser was safe only if the groove was designed properly and the shaping technique of the circular groove was very well.
