| Abstract: | The lasting experiment was carded out on the creep rupture test of P91 steel and welded joint, and the creep properties of P91 steel were studied. The creep rupture strength was extrapolated by the isothermal extrapolating method and L-M method, and the creep life of P91 main steam pipe was estimated. |
