minimum pipe spool length

hi all,

   May anyone tell what will be the minimum possible pipe spool length for a butt welded end connection.

   As per AWS the minimum pipe spool length required in a line is one NPS.    where site condition restricts this minimum requirement, is it possible to adopt

   lesser length spools.

   thanks and regards,
