Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless TP347H cold-drawn specs
Material family (stainless vs other alloy) drives primary classification split.
If electric resistance welded
Welding method excludes from seamless tube headings entirely.
If fitted for specific steam generator assembly
End-use as HRSG parts supersedes raw tube classification.
