卧式压力容器选型的质量预估方法

Pre-estimating Method to Type-selecting Quality of Horizontal Pressure Container

在卧式压力容器型号和基本参数选择中 ,对设备质量进行比较是必不可少的。为了用较短的时间给出比较精确的预测 ,在综合考虑壳体、封头、鞍座和内构件等结构部件的质量 ,以及计算厚度、钢板厚度负偏差、腐蚀裕量和厚度圆整度等设计环节的基础上 ,提出了设备质量预估方法 ,给出了完整的计算公式 ,然后以固定管板式换热器为例 ,重点进行了内构件分析 ,并用实际数据加以计算说明 ,最后根据总质量最小的原则 。

In order to getting more exact forecast in shorter time,on the basis of comprehensive consideration the design links such as the quality of shell,head,saddle and inner components structure parts etc and design links such as counting thickness the minus errors of plate thickness,corrosion allowance and the perfectness of circle etc the article puts forward pre-estimating method to equnpment quality and shows a complete calculation formulas.
