Large-diameter (over 16 inches) threaded alloy steel casing pipe designed for oil well drilling, featuring API-standard couplings for secure connections in borehole lining. Classified under HTS 7305.20.60.00 due to its circular cross-section exceeding 406.4 mm, alloy steel composition, and threaded/coupled ends specific for oil/gas drilling applications. The welded construction and size distinguish it from smaller pipes or non-casing tubes.
