INSPECTION CLASSIFICATIONS

Used Tubing/Casing	New Tubing/Casing (and Plain End Drill Pipe)	Used Drill Pipe
*Yellow Band: 0-15% body wall reduction (85% min. remaining)	*White Band: suitable for all inspections performed (incl. min. 87.5% body wall).	Double White Band (Premium): 80% minimum wall remaining
*Blue Band: 16-30% body wall reduction (70% min. remaining)	*Yellow Band: Repairable reject. 87.5% body wall remaining after repair. Locate bands on either side and circle around defect.	Yellow Band: 70% to 80% (min.) of nominal wall remaining.
*Green Band: 31-50% body wall reduction (50% min. remaining)	*Blue Band: Imperfections of undetermined depth. Identified as above.	Orange Band: <70% (min.) of nominal wall remaining.
*Red Band: 50%+ body wall reduction (<50% remaining)	*Red Band: Defective length. Identified as above. Body wall defects must be cut out of tube.	Red Band: Any tube with a hole or a fatigue crack.
Damaged pin or box ends marked with red bands next to pin or on coupling	Damaged pin or box ends marked with red bands next to pin or on coupling	Tool joint classification color bands appear on the pin or box. Shoulder condition color codes are adjacent to the threads.
Drift restrictions indicated by green bands on either side of restriction and another next to body wall color band near box	Drift restrictions indicated by red bands on either side of restriction – just like other defects.	N/A
*Bands on tube body next to box end or coupling	Tube classification bands appear in same location (box end) as on used material.	Tube classification color bands appear next to the pin
