摘　　要：在进行非标带颈对焊法兰设计时,根据计算,法兰盘、锥颈的尺寸有明确的确定方法,然而,对接圆筒段的尺寸确定方法在标准规范中未有明确的说法。本文通过规范及相关文献的描述,总结并比较了几种确定对接圆筒段尺寸的方法。When designing non-standard weld neck flanges,there are clear method for determining the dimensions of the flange disc and the neck section according to calculations.However,there is no clear specification for the dimensions of the butt-welded cylindrical section in the codes and standards.Through the descriptions in the standards and relevant literatures,this paper summarizes and compares several methods for determining the dimensions of the buttwelded cylindrical section.
