When measuring blast furnace gas, the pressure guiding pipe is relatively long – is insulation or heating necessary?

The company is in the north, and a elbow flow meter is to be installed on-site. The pressure guide tube is installed at the top of the pipeline; due to the large diameter of the pipeline, the pressure guide tube is quite long. Is it necessary to provide insulation and heating in winter?
The purpose of insulation and heating is to prevent freezing and condensation; if the medium does not freeze or condense, then insulation and heating are not necessary. When considering whether a medium will freeze or condense, it is necessary to take into account the presence of substances that can cause condensation. For example: whether condensation water is formed in the air when its moisture content is below the dew point.
Get insurance; although theoretically the condensed liquid will flow back into the pipes, extreme weather conditions cause rapid freezing as well.
You don’t even need to think about it – for pressure pipes of this length, regardless of the medium used, it’s sufficient to provide heat tracing.
It is necessary; the moisture content in blast furnace gas is usually saturated water, and it can indeed freeze at low ambient temperatures
There should be insulation; although it’s not really necessary in most cases, it could still damage your instruments if something goes wrong
Daoran needs it; blast furnace gas has a high water content! Any gas containing water must be insulated and heated when it freezes!
The steam situation on my end is the same as yours; on top of that, it freezes frequently, not to mention when no steam is used at all
Which instruments require insulation and which require heat tracing? What factors should be considered?
In practice, it’s best to have pictures; who can know how your pipes are arranged?
