| Abstract: | The paper described the manufacturing process of a thick-wall cylinder simulation tube made by 38CrNi3MoV steel, and the hydraulic pressure cycle fatigue life of the tubes was tested. The result indicated that the mechanical properties of the two ends of the six simulation tubes manufactured in the lab were: Rr0.1 1 270～1 320 MPa,A 13%～18%,Z 45%～54%,-40 ℃ Akv 25～ 37 J. Under the cycled pressure of 600 MPa,the safety fatigue life of the simulation tubes was 1 807～3 449 times. |
