摘　　要：主要介绍了在线取样、实验室制样、鼓胀测试分析的全流程技术实现,并以超期服役的加氢反应器为在线取样测试分析工程应用对象,测得了设备本体材料的力学性能。发现屈服强度和抗拉强度都发生了弱化,远离焊缝处屈服强度降低14.5%,抗拉强度降低9.8%,靠近焊缝处屈服强度下降微小,抗拉强度降低3.6%。这给设备安全评估提供了真实的力学性能数据,验证了方法的可行性和可靠性。This paper mainly introduces the technological realization of the whole process of online sampling,labo-ratory sample preparation and bulging test analysis,and takes a hydrogenation reactor that has been out of service as an application object of online sampling test and analysis engineering to measure the mechanical properties of equip-ment body materials.It is found that both the yield strength and tensile strength are weakened,the yield strength is reduced by 14.5%and the tensile strength by 9.8%away from the weld,and that the yield strength decreases slightly and the tensile strength by 3.6%near the weld,which provides real mechanical property data for equipment safety evaluation,and verifies the feasibility and reliability of the method.
