蒸汽发生器关键焊接技术
|
摘要
":华龙一号"蒸汽发生器是我国自主研发的三代核电技术,主要介绍其结构特征、关键部位使用的焊接材料和工艺要求,并详细论述了下封头内壁不锈钢堆焊、管板堆焊、管子/管板封口焊、接管安全端焊接技术等关键焊接工艺的实现方式,为后续"华龙一号"蒸汽发生器的批量化制造奠定了基础,提供了有力的技术保证。
HPR1000 steam generator is the third generationa nuclear power technology which be developed independently by China.This paper introduces the structural characteristics of HPR1000 steam generator,and describes the welding materials and process requirements for its key parts. Meanwhile,the key welding processes to be implemented,such as the stainless steel cladding weld of primary head,tube sheet cladding weld,tube-to-tube sheet weld,primary nozzle safe end weld,have been introduced in detail. It lays a foundation for the mass production of subsequent HPR1000 steam generator and provides a powerful technical guarantee.
