Is heat tracing required for double flanges?
Thread Content
The operating temperature of silicone oil in double-flange designs is 0 to 200 degrees Celsius; however, the ambient temperature at the installation site might be below 0 degrees Celsius. Is it necessary to install heating in such double-flange systems, and will the silicone oil vaporize if heating is used?

The ambient temperature is different; we didn’t heat it up, but it works fine.

It is difficult to ensure that the heat supply in the capillaries on the positive and negative pressure sides is equal; otherwise, it will affect the measurement results.
Is the silicone oil in the dual-flange level gauge used by the poster of the high-temperature type? How hot can your heat tracing be? ! Do you also want to bake and vaporize silicone oil? !
The key factors are operating conditions, operating temperature, material properties, and whether it’s indoors or outdoors?
I don’t think heat tracing is necessary. What is the temperature below zero at which it can be used?
In most cases, insulation and heating are not necessary, as the design institute takes the ambient temperature into account when selecting the appropriate components; however, it is still a good idea to verify this yourself. Capillaries also have temperature tolerance ranges, and it is necessary to consult relevant information to determine what the temperature tolerance range of the capillaries in the selected equipment is. The process flange and mounting stub can be insulated and heated.
