摘　　要：压力容器在化工、核电、环保、医药等工业领域广泛应用,为满足工艺操作、容器制造、安装、检验及维修等要求,在设备上开孔是不可避免的。压力容器壳体或封头上的开孔会削弱容器壁的强度,且在开孔附近会形成应力集中,因此需要对容器开孔进行补强设计。ASME BPVC.Ⅲ是核电设备主要技术标准之一,本文介绍了该规范的开孔补强要求,并结合具体算例为类似核级设备开孔补强设计计算提供参考。Pressure vessels are widely used in chemical industry,nuclear power,environmental protection,medicine and other industrial fields.The opening of the pressure vessel shell or sealing head will weaken the strength of the vessel wall,and the stress concentration will form near the opening,so the reinforcement design of the vessel opening is needed.ASME BPVC.Ⅲ is one of the nuclear power equipment main technical standards,this paper introduces the opening of the specification requirements,and combined with concrete example for the similar nuclear level devices opening reinforcement design calculation to provide the reference.
