Subheadings
Products classified under HTS 7304.22.00
13Cr Stainless Steel Drill Pipe 4-1/2 Inch OD
Seamless 13% chromium (13Cr) stainless steel drill pipe, 4-1/2 inches outer diameter, used in corrosive environments like sour gas wells. Equipped with premium connections for high-pressure drilling, it provides superior corrosion resistance over carbon steel. Falls under HTS 7304.22.00 due to its seamless construction and specific design as drill pipe for oil/gas drilling.
Super Duplex Drill Pipe 5-7/8 Inch High Pressure
Super duplex stainless steel drill pipe (e.g., SAF 2507), 5-7/8 inch OD, for ultra-high pressure and H2S-resistant drilling in harsh oilfields. Seamless construction with integral upset ends for enhanced joint integrity. Classified in 7304.22.00 for stainless steel seamless drill pipe used in oil/gas drilling.
Martensitic Stainless Drill Pipe 3-1/2 Inch Slim Hole
Martensitic stainless steel (e.g., 410/420 grade) drill pipe, 3-1/2 inch OD for slim hole drilling in oil exploration. Seamless with high hardness for abrasive formations. Under 7304.22.00 as stainless steel seamless drill pipe for oil/gas.
Austenitic Stainless Steel Drill Pipe 7 Inch Extended Reach
Austenitic stainless steel drill pipe (e.g., 316L), 7 inch OD for extended reach horizontal drilling in shale oil plays. Seamless with low cycle fatigue design. 7304.22.00 for stainless drill pipe.
