摘要
ASME B31．3-2004与ASME B31．3-2002相比,作出了一些重要变更,这些变更涉及焊缝接头强度降低系数W、应力范围系数f,用于高应力范围的另一种规则、高温情况下针对偶然载荷的另一种许用应力、膨胀节的特殊设计要求等,笔者针对这些变更作出说明。
A series of technical changes were made in the 2004 edition of process piping code ASME 1331.3. Changes in the following topics are presented:Weld joint strength reduction factors W,stress range factor f,alternative rule for flexility analysis,alternative al- lowable stress for occasional loads at elevated temper- atures,etc.
