We have to replace about 8 section on a 8" NPS pipe with Wt 0.188". The available pipe joints are of slightly higher schedule #20 thk 0.25" and #40 thk 0.322.
Could some one please clarify if these sections may cause problem for intelligent pigging?
As intelligent pig is normally 95% of pipe bore, I think these replaced sections will not pose any problem as ID difference between pipe sections with different schedules will be 3.2% max.
Any comments will be appreciated.
