I would like to ask the teachers here: for a new device, there is a thermocouple port, and the flange uses size 20. What should be the size of the thermocouple sleeve? Thank you all for your valuable advice
Choose the instrument first, then determine the interface!
Thank you, teacher, for your help. I’m still a beginner and don’t quite understand it yet. Now, thermocouples need to be installed on the new equipment; I’m not sure what size they should be. If a 20-size flange is used, what size opening does that mean for the equipment?
The flange size is relatively small; sizes 14 and 16 will work as long as they can fit in. It is necessary to consider the pressure exerted during equipment operation, as well as the required wall thickness of the sleeve; otherwise, the manufacturer will simply use stainless steel gas pipes.
The pressure is 16 kilograms, and the temperature can reach over 150 degrees. Can stainless steel be used? I’m just worried that if the opening is too small, the thermocouple won’t fit in. Thank you very much for your advice; I’m extremely grateful
It’s possible; the temperature and pressure levels are not high. Stainless steel is suitable, as well as flanges of size 20. The outer diameter of the sleeve can be φ16, or it can even be smaller – just explain the situation to the manufacturer directly
Use a thermistor for 150 degrees. Both 16 and 14 for sleeve diameter are acceptable
Okay, thank you. Now I’m relieved
Mm-hmm, I’ll consider it. Thank you!
