Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of high-strength low-alloy steel types
HSLA variants have dedicated provisions within cold-drawn alloy steel tubes.
If for cold-formed tubes not boiler-specific
Lack of documented end-use for boilers shifts to general cold-drawn other alloy tubes.
If cut and threaded for pipe fittings in boiler systems
Threaded or coupled tubes become pipe fittings under 7307 rather than raw tubes.
