Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If precision seamless for measurement
Tight tolerances may qualify as instrument tubing outside drilling.
If buckets/buckets for drilling rigs
Wait, no—actually for casing handling equipment parts.
If casing with larger diameter
Same specs but OD >114.3 mm changes subheading.
