摘　　要：本文对安全阀排放管常见的流通截面积变小、随意变更排放管材料、排放管焊缝强度不足、安装超差、无固定支架等设置不合理现象进行了分析和讨论,并对排放管不合理设置危险点处的应力给出了标准中的理论计算公式和一起事故的应力计算结果。提出了安全阀排放管在设计、安装、检验时应注意的内容和要求,并进一步建议相关安全技术规范和标准在修订时增加相应内容。In this paper, the common unreasonable settings of relief valve discharge pipe are discussed, such as： flow cross-sectional area wane, material alteration, weld strength insufficient, out-of-tolerance installation, no fixed support. The theoretical stress calculation formula in standard for dangerous point in discharge pipe caused by unreasonable setting is given, and the stress calculation result was calculated for an accident. The major content and requirements are proposed in the aspect of design, installation, and test. This paper also suggests adding corresponding content in the revision of relevant technical specifications and safety standards.
