摘要

以国内某核电建设项目为依托

在分析核电站常规岛主蒸汽和主给水管道用钢特点的基础上

广泛搜集、调研国内外同类管道用钢并进行了对比分析与论证

最终确定采用WB36CN1作为核电站常规岛主蒸汽和主给水管道用钢。经过优化化学成分

控制完善制造冶炼工艺

并将管道规格标准化、系列化设计

最终形成WB36CN1国产化技术规范。首批试制的WB36CN1无缝钢管各项性能指标均达到了德国Vd TüV 2001年版459/2WB36S1的技术要求

并成功应用于该核电站。

Abstract

On the basis of a domestic nuclear power construction project and analysis on material characteristics that the main steam and main feedwater pipeline of the conventional island in nuclear power plants should have

the material selection of domestic and foreign congeneric pipelines were widely collected and studied.Moreover

demonstration and comparative analysis were sufficiently conducted.Finally

the WB36 CN1was chosen as the material for main steam and main feedwater pipes in conventional island of the 1 000 MW nuclear power plant.Via optimizing the chemical composition

controlling the manufacture and smelt process

serializing and standardizing the piping dimension

the WB36 CN1localization technical specification was ultimately formed.Performance of the first batch trial-produced WB36 CN1seamless pipes was fully satisfied with the requirements of WB36S1in German Vd TüV 459/2(2001version).At last

the mass production pipes were successfully applied to this nuclear power plant.
