P91主蒸汽管道焊接接头的蠕变特性和寿命估算
Creep Properties and Creep Life Estimation of Welded Joint for P91 Main Steam Pipe
【摘要】 对P91钢母材和焊接接头进行持久试验,研究P91钢的蠕变特性,采用等温线法和L-M参数法对持久强度进行外推,进而对P91钢制主蒸汽管道的蠕变寿命进行估算。
【Abstract】 The lasting experiment was carried 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.
