What is the typical temperature for natural gas transportation?

What is the typical temperature for natural gas transmission? I’d like to ask. . .
There are generally three ways to transport natural gas: by ship, by truck, and by pipeline. For shipping by sea and road, transport is carried out at normal pressure and low temperature (-162 degrees Celsius), that is, in liquid form ； Whether it is transported through pipelines or in gaseous form, there shouldn’t be any particular requirements regarding temperature. There are still some technical difficulties in the pipeline transportation of liquefied natural gas, and there are no existing examples of its application
First, we extract the gas, remove water from it using a dew point device (with the temperature of this device controlled at -5 to -18°C), and then conduct heat exchange through a heat exchanger. At the beginning of gas extraction, the outlet temperature is quite low, around a few degrees or even a few degrees below zero; after that, it is generally around 15 degrees
Generally, natural gas is transported via pipelines, and the pipelines in oil fields are usually buried; it is transported in gaseous form, with no particular requirements regarding temperature.
3-5° above the dew point is sufficient (for pipeline transport of gaseous natural gas)
Buried pipeline transportation has basically no requirements regarding temperature, as we cannot control the temperature of the natural environment; however, if the dew point of the gas is well controlled, it is theoretically possible to extend the lifespan of the pipelines...
For buried natural gas pipelines, since they are buried below the freezing level of the soil, the temperature is generally around 0–20 degrees, depending on the climate in the location of the project. Of course, if it’s buried shallowly, temperatures over 20 degrees are also quite common.
0~20 degrees, the temperature on long-distance pipelines.
Are there any relevant standards that can be consulted regarding gas pipeline transportation?»
