Products classified under HTS 7307.93.90.60
Alloy Steel Butt-Welding Tee 450mm ID
A tee junction fitting of non-stainless alloy steel for butt-welding, featuring an inside diameter over 360 mm, ideal for branching large pipelines in petrochemical plants. Its robust construction handles extreme temperatures and pressures. Falls under 7307.93.90.60 for its specific large ID, alloy material, and welding method.
Alloy Steel Butt-Welding Cap 380mm ID
A pipe end cap of alloy steel (non-stainless) for butt-welding, with inside diameter over 360 mm, sealing off large pipelines in construction or maintenance projects. Ensures pressure-tight closures. Classified in 7307.93.90.60 for its material, size, and welding type.
Alloy Steel Butt-Welding Spectacle Blind 450mm ID
Spectacle blind (figure-8) fitting of non-stainless alloy steel for butt-welding, 450mm ID, used to isolate pipe sections in refineries. Switches between blind and spacer. Under 7307.93.90.60 for large butt-weld alloy fittings.
Alloy Steel Butt-Welding Wye 500mm ID
Wye branch fitting (Y-shaped) of alloy steel excluding stainless, butt-welding with 500mm inside diameter, for drainage or slurry lines in mining. Facilitates smooth flow splits. 7307.93.90.60 classification for specified attributes.
Alloy Steel Butt-Welding Elbow 400mm ID
A large-diameter elbow fitting made from alloy steel (non-stainless) designed for butt-welding into piping systems, with an inside diameter exceeding 360 mm. It is used in high-pressure industrial applications like oil refineries and power plants where strength and corrosion resistance are critical. Classified under 7307.93.90.60 due to its butt-welding design, alloy steel composition excluding stainless, and large internal diameter.
Alloy Steel Butt-Welding Reducer 500mm ID
A concentric reducer fitting from non-stainless alloy steel, butt-weldable with inside diameter of 500 mm or more, used to connect pipes of differing sizes in water treatment or mining operations. Provides seamless transitions in large-scale piping. HTS 7307.93.90.60 applies for large ID butt-welding fittings excluding stainless alloy steel.
Alloy Steel Butt-Welding Cross 420mm ID
A four-way cross fitting made from non-stainless alloy steel for butt-welding applications, inside diameter exceeding 360 mm, used in complex large-diameter piping networks like desalination plants. Allows multi-directional flow. Meets 7307.93.90.60 criteria for large alloy butt-welding fittings.
Alloy Steel Butt-Welding Equal Tee 600mm ID
Equal-branch tee fitting of non-stainless alloy steel, butt-weldable with 600 mm inside diameter, for ultra-large piping in power generation or shipping. Provides balanced flow distribution. HTS 7307.93.90.60 due to size, material, and butt-weld specificity.
