摘要

制造公差在波纹管的可靠和一致的性能中起着重要作用。本文讨论了标称尺寸变化对波纹管性能的影响，以及各种核应用中波纹管制造公差的选择指南。提出了一套新的指导方针，用于选择各种类型的波纹管(即成形和焊接圆盘波纹管)在各种服务载荷下的制造公差。ASME第iii节/规范案例N290中给出的规则建议用于所有1级成型波纹管。EJMA中给出的准则被推荐用于选择ii类加载条件下成形波纹管的制造公差。本文还介绍了基于各种制造试验的焊接圆盘波纹管制造公差选择新规则的发展，并通过实例对所提出的规则进行了论证。

Manufacturing Tolerances of the bellows for nuclear applications - Case study

Manufacturing tolerances play a major role in the reliable and consistent performance of the bellows. This paper discusses the effect of the change in the nominal dimensions on the performance of bellows and guidelines for selection of manufacturing tolerances for the bellows used in various nuclear applications. A set of new guidelines for selection of manufacturing tolerances for various types of bellows (viz. formed and welded disc bellows) under various service loadings was proposed. The rules given in ASME section-III/code case N290 were recommended for all class-1 formed bellows. The guidelines given in EJMA were recommended for the selection of manufacturing tolerances of formed bellows with class-II loading conditions. This paper also presents the development of new rules for the selection of manufacturing tolerances of welded disc bellows based on various manufacturing trials and the proposed rules are demonstrated through a case study.
