Products classified under HTS 7307.91.10.00
Rough Forged Steel Slip-On Flange
Unprocessed forged flange of nonalloy steel that slips over pipe ends for welding, used in low-pressure applications like water systems. No machining after forging, meeting the raw state for this HTS. Falls under 7307.91.10.00 due to its iron/nonalloy steel construction and forging process.
Rough Forged Steel Threaded Flange
Forged nonalloy steel flange intended for threaded pipe connections, supplied in unmachined state after forging. Used in plumbing and light industrial setups. Classified in 7307.91.10.00 for its material and lack of post-forging work.
Forged Nonalloy Steel Long Neck Flange
Extended neck forged flange from nonalloy steel, unmachined, for high-stress pipeline connections. Provides reinforcement without welding hub. Fits 7307.91.10.00 as a basic forged flange.
Rough Iron Orifice Flange
Forged iron flange pair for flow measurement with orifice plate, supplied rough post-forging. Used in oil/gas metering. 7307.91.10.00 for nonalloy, unmachined state.
Forged Iron Raised Face Flange Blank
Basic forged blank for raised face flanges of nonalloy steel/iron, completely unmachined. Later machined by importer. Strictly 7307.91.10.00 for raw forging.
Rough Forged Nonalloy Steel Spectacle Blind Flange
Figure-8 forged flange for alternating flow/blind positions, nonalloy steel, unmachined. Used in process plants. 7307.91.10.00 classification.
Unprocessed Steel Paddle Flange
Forged paddle/spacer flange of nonalloy steel for spacer duties in piping, rough state. Common in maintenance. Fits unmachined criteria of 7307.91.10.00.
Forged Iron Pipe Spool Flange
End flange for pipe spools, forged nonalloy iron, no machining. For prefabricated sections. 7307.91.10.00 as individual fitting.
Rough Nonalloy Steel Expansion Flange
Forged expansion joint flange for thermal movement, nonalloy steel rough. Industrial HVAC use. Unmachined per 7307.91.10.00.
Unmachined Forged Steel Swivel Flange
Rotatable forged flange ring of nonalloy steel, rough for swivel alignment. Pipeline use. 7307.91.10.00 raw.
Forged Carbon Steel Weld Neck Flange
A rough-forged flange made from nonalloy steel, designed for welding onto the end of pipes in industrial piping systems. It features a neck extension for strength under high pressure. Classified under 7307.91.10.00 as a flange of iron or nonalloy steel, not machined, tooled, or processed after forging.
Unmachined Forged Iron Blind Flange
A solid forged disc of iron or nonalloy steel used to cap pipe ends, in rough forged condition without machining. Ideal for temporary closures in construction. HTS 7307.91.10.00 applies as it's a non-processed forged flange of qualifying material.
Forged Nonalloy Steel Socket Weld Flange
Rough-forged flange with a socket for pipe insertion and fillet welding, made from nonalloy steel for moderate pressure systems. No further processing post-forging. Meets 7307.91.10.00 as an unmachined forged pipe fitting flange.
Unprocessed Iron Lap Joint Flange
Forged flange of iron/nonalloy steel with a lap extension for stub-end joints, rough condition post-forging. Facilitates easy alignment in piping. HTS 7307.91.10.00 due to forging without subsequent machining.
Unmachined Steel Reducing Flange
Forged nonalloy steel flange that connects differing pipe sizes, rough forged condition. Essential for transitions in ductwork. Under 7307.91.10.00 as unmachined.
