Vague questions, vague explanations — the process requires this: lol. It’s recommended to provide more detailed schematic diagrams of the relevant processes or written descriptions. For example, what kind of device it is, and so on.
It is estimated that the outlet temperature is too low, which will cause problems in subsequent processes; therefore, interlock protection is required.
Please check the material of the pipeline – is it ordinary carbon steel, or low-temperature steel/austenitic stainless steel?
The phase state of the material under the current temperature and pressure, as well as the temperature, pressure, and material properties of the downstream equipment, to determine whether they meet the requirements.
What process? Is this temperature measurement for a process pipeline? Or sealed gas, etc.!
