Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for pressure line service
High-pressure application tubes classify under line pipe headings.
If cut-to-length <2m
Short lengths processed as fabricated articles, not tubes.
If irregular noncircular shapes
Complex cross-sections beyond square/rect go to other hollow profiles.
