鞍座热膨胀计算 项目号 ITEM NO.
Saddle Thermal Expansion calculation
文件号 DOC. NO.
注:
输入数据 Input Data 1. 热膨胀系数参考表 10-6mm/mm°C
1 1
FIG: saddle base plate anchor bolt hole
设备材料The material of vessel SA-240 316L
最高设计温度The max. design temperature T1= 200 °C
最低设计温度The min. design temperature T2= -29 °C
设备材料在最高设计温度下的热膨胀系数
The expansion coefficient at the max. design temperature
a1= 1.73E-05 mm/mm°C
设备材料在最低设计温度下的热膨胀系数
The expansion coefficient at the min. design temperature
a2= 1.60E-05 mm/mm°C
鞍座间距The distance of saddle L= 2000 mm
鞍座底板长圆孔长度
The slot hole of saddle base plate
e= 30 mm
设计计算 Checking strength
设备的安装温度
 The install temperature
t= 21.1 °C
最高设计温度下热膨胀长度
The expansion length at max. temp. 
ΔL1=a1L(T1-t)= 6.17  mm
最低设计温度下热膨胀长度
The expansion length  at min. temp.
ΔL2=a2L(T2-t)= -1.60  mm
最大热膨胀长度
The max. expansion length
ΔL=max(|ΔL1|,|ΔL2|)= 6.17  mm
判别依据 Evaluate ΔL <= e/2
The slot hole length is OK!
