Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically butt-welding (e.g., slip-on)
Non-butt-welding 'other' fittings of alloy steel fall into broader categories.
If inside diameter 165mm to 359mm
Mid-range diameters have distinct statistical suffixes within butt-welding alloy steel.
If imported as integral part of turbocharger housing
End-use as machinery part may classify under pumps or machinery chapters.
