Hi Bip,

There could be many reasons. 


You could look up the plant piping line list to see how their design conditions differ, such as for pressure, temperature, contaminants such as pH level, hydrocarbons, perhaps one is closed to atmosphere and one is open (vented).  Or is there two lines simply because of distance. Therefore they may be different materials of construction , or may have a different destination.


Please let us know what you find out so that we all may learn....
