What is the superheat of the steam in the pipeline network? !

Assuming 6 kgf of steam, there is usually some superheat; what is this amount of superheat? Are there any standard regulations?
There’s no requirement for that; to minimize losses, it’s usually overheated by about 20°C. Our 6 kilograms of steam is at around 190°C.
Oh, I see. Then it’s also over 20 degrees too.
There is no strict requirement; sometimes the superheat of the steam supplied by the power plant to our company can be 100 degrees
Is the pipe insulation in power plants that poor?
“Is the pipe insulation in power plants really that poor? Under certain operating conditions, steam must have a certain degree of superheat at the point of use; saturated steam cannot be used in such cases.
The superheat of superheated steam for various applications varies; for example, in power generation boilers, at 9.8 MPa and 540°C, the superheat is approximately 230°C, while at 3.82 MPa and 435°C, it is about 188°C. The superheat of the steam produced by other types of boilers other than thermoelectric boilers also varies depending on the requirements of subsequent processes; it can be 30°C superheated or even 50°C superheated, with all these values being determined by the process conditions in which they are used.
