Products classified under HTS 7307.21.10.00
Forged Stainless Steel Weld Neck Flange
A rough forged stainless steel flange designed for welding to pipes in piping systems, left unprocessed after forging with visible forging marks. Classified under HTS 7307.21.10.00 as a stainless steel flange not machined, tooled, or otherwise processed post-forging. Used primarily in industrial applications like chemical processing.
Rough Forged Stainless Steel Slip-On Flange
Unfinished forged stainless steel slip-on flange for easy pipe attachment via welding, retaining forging scale and no surface treatment. Falls under HTS 7307.21.10.00 due to stainless steel construction and lack of any post-forging processing. Common in oil and gas pipeline assemblies.
Forged 304 Stainless Steel Blind Flange
Roughly forged 304-grade stainless steel blind flange used to cap pipe ends, unprocessed with hammer marks intact. HTS 7307.21.10.00 applies as it's a stainless steel flange not further worked after forging. Essential for pressure vessel closures in refineries.
Unprocessed Stainless Steel Socket Weld Flange
Forged stainless steel socket weld flange in raw state for socket welding to pipes, no machining applied post-forging. Meets HTS 7307.21.10.00 for other stainless steel flanges not tooled after forging. Applied in high-pressure sanitary piping.
Forged Duplex Stainless Steel Flange Blank
Rough forged duplex stainless steel (2205 grade) flange blank for extreme pressure applications, unprocessed after hammer forging. HTS 7307.21.10.00 covers such stainless steel flanges not otherwise worked. Used in subsea oil recovery.
Raw Stainless Steel Long Neck Flange
Forged stainless steel long neck flange in raw form for high-stress welding, no post-forging treatment. Fits HTS 7307.21.10.00 for unprocessed stainless flanges. Prevalent in power plant steam lines.
Unfinished 304L Stainless Steel Plate Flange
Rough forged 304L stainless plate flange for general piping, preserved in as-forged condition. HTS 7307.21.10.00 for stainless steel flanges not machined post-forging. Suited for pharmaceutical cleanrooms.
Rough Forged 316L Stainless Steel Flange
316L stainless steel flange forged for corrosion resistance in marine environments, supplied rough without processing. Classified in HTS 7307.21.10.00 as unprocessed stainless steel flange. Ideal for offshore platforms.
