One big benefit of running the line at a higher pressure is that you can fit much more steam in it (over 30%). The downside is you get more energy loss due to the higher temperature.
One good question for you is: Do you have a pressure reducing valve between the boiler and the 'line' or is the boiler output controlled on the line pressure?? Then, if you do have subsequent pressure reducing valves, the sizing of these valves must be looked at again if you increase the line pressure. You will also need to look at the steam traps on the line (especially if they are F&T or Buckets) to be sure they have the correct orifice in them.
