Here pipe surfaces are checked for discontinuities and steel defects. Small
pits, seams, slivers or scabs are removed by grinding or filing to reduce
coating flaws known as "holidays." Defects exceeding the American
Petroleum Institute 5L Standard are marked, recorded and removed from the
production line for further non-destructive evaluation.
