摘　　要：火力发电现已成为电力供应的主要方法之一。然而,随着服役时间的增长,工况环境恶劣的零部件的蠕变已成为影响其使用寿命的因素。利用现有的力学性能检测设备,主要对板试样、圆试样或管试样进行高温蠕变试验,还不能同时在温度、力、水蒸气环境、烟气环境下进行整体管试样的高温蠕变试验。依据工程实际需求,研制了高温水蒸气环境管道蠕变试验机。Thermal power generation has become one of the main methods of power supply.However,with the increase of service time,the creep of parts in poor working conditions has become a factor affecting its service life.In the existing mechanical performance testing equipment,the samples of high temperature creep test mainly include the board sample,the round sample or the tube sample,and the high temperature creep test for integral tube sample has seldom been finished simultaneously in the temperature,the force,the vapor environment and the flue gas environment.
