INSPECTION CLASSIFICATIONS
New Tubing/Casing
(and Plain End Drill Pipe)
*White Band: suitable for all inspections performed (incl. min. 87.5% body wall).
*Yellow Band: Repairable reject. 87.5% body wall remaining after repair. Locate bands on either side and circle around defect.
*Blue Band: Imperfections of undetermined depth. Identified as above.
*Red Band: Defective length. Identified as above. Body wall defects must be cut out of tube.
Damaged pin or box ends marked with red bands next to pin or on coupling
Drift restrictions indicated by red bands on either side of restriction - just like other defects.
Tube classification bands appear in same location (box end) as on used material.
