引言用于石油裂化和煤转化的反应压力容器是在高温、高氢压和腐蚀严重的介质中使用的,必须采用厚壁压力容器和先进可靠的制造工艺,如焊接和堆焊。为了保证反应器的安全,设计、制造和运行都必须考虑周密。在能源工业的核能领域中,厚壁压力容器是压水堆核电站的心脏部分,必须达到高标准的材料质量和加工操作以满足所要求的完整性。容器都很大,重量为300～400t、筒体
Introduction Reactors for petroleum cracking and coal conversion are used in media at high temperatures, high hydrogen pressures and severe corrosion. Thick-walled pressure vessels and advanced and reliable manufacturing processes, such as welding and surfacing, must be used. In order to ensure the safety of the reactor, the design, manufacture and operation must be carefully considered. In the field of nuclear energy in the energy industry, thick wall pressure vessels are the heart of pressurized water reactor nuclear power plants and must meet a high standard of material quality and processing operations to meet the required integrity. Containers are large, weighing 300 ~ 400t, cylinder
