Determination of the pipe diameter at the temperature measurement point
Thread Content
I would like to ask the experts: In medium and low-pressure pipelines, at the locations where temperature measurement points are required, how is the diameter of the pipe at the installation site determined, whether it comes to on-site indicators or those controlled from a central station? Shouldn’t it be at least a DN80 pipe? Thank you for your guidance!
The ethylene glycol aqueous solution pipeline here uses DN840 pipes equipped with temperature transmission devices.
It can’t be determined so roughly; it depends on the diameter of your pipes. If the pipe diameter is only 10 mm, then using a DN80-sized temperature sensor isn’t appropriate. It’s important to have a proper ratio so that temperature measurements can accurately reflect the actual temperature of the pipes
Are there any regulations regarding the places where temperature measurement points are to be installed? If the pipe diameter needs to be increased, what is the specific ratio required? Where can I find it?
