摘要
对于直埋地下的管道,由于环境热阻比较复杂,其传热计算方法尚不统一。文章通过对国内外的几种传热计算方法进行分析对比,并结合多年管道保温工作的实践经验,就直埋保温管道环境热阻率的计算、保温厚度的计算、热影响范围的计算提出建议,与同行探讨。
There is no uniform calculation method for buried directly pipeline because of more complicated circumstances of thermal resistance. This paper discussed the calculation of circumstance thermal resistance, thickness of thermal insulation and its affecting ranges by analyzing and comparing the several heat transfer calculation methods and by combining long-time practical experiences in such area of the authors. Some proposals were also presented.
