Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied in random lengths >12m
Very long tubes may classify under line pipe headings if not drilling-specific.
If wall thickness exceeds 9.5 mm
Thicker walls shift to the >9.5 mm wall thickness statistical suffix.
If parts of drilling rigs
If imported as replacement parts for specific rigs rather than generic tubing.
