if u recollect the equation,
resistance (r)= pl/A;
where p=specific resistivity
l= length
A= cross sectional area
Area = pie(3.414) * r2
but diameter is twic the radius.
hence insulation thickness is dependent on pipe diameter.

A small-diamter pipe requires more insulation. A very large-diameter pipe needs none because the contents of the pipe provide the insulation.

it is not only the pipe diameter it is the seknes of the pipe the material the pipe mad from and the temprutour of the fiow insid the pipe
