Description

热安装保护套管

热电偶、热电阻的保护套管是套在测温元件之外,起着抵御测量介质的压力和腐蚀作用,使测温元件的输出能精确地反映被测温度的高低。
根据被测温度的高低、介质种类、压力大小和安装形式的不同,保护套管可分为三类:固定螺纹式、无固定焊头式和固定法兰式。

整体钻孔型保护管的特点为:

(1)密封可靠性高;
(2)因无焊接引起的热应力及晶粗张大现象,因此抗腐性能比焊接管好。

随着所选材料种类和使用温度的不同,应将公称压力作合理的降额后,作为使用的工作压力。

 

公称压力

一般是指在常温下,保护管所能承受的静态外压而不破裂。允许工作压力不仅与保护管材质、直径、壁厚有关,且与其结构形式、安装方法及被测介质的流速、种类有关。
