Products classified under HTS 7306.29.60
2-3/8 Inch N80 Tubing
2-3/8" OD N80 grade nonalloy tubing for gas lift and injection applications in oilfield operations. Falls under HTS 7306.29.60 due to its specialized use in drilling/production. Lightweight design suits long string deployments.
2-7/8 Inch Continuous Sucker Rod Tubing
2-7/8" nonalloy steel tubing designed for continuous sucker rod pump installations in stripper wells. HTS 7306.29.60 covers this iron/nonalloy tubing used in oil production drilling phases. Enhanced collapse resistance for artificial lift.
2-3/8 Inch ESP Tubing
2-3/8" tubing for Electrical Submersible Pump (ESP) installations in oil production. Nonalloy steel construction qualifies for HTS 7306.29.60 as iron drilling tubing. Cable strap grooves and pump seating nipples included.
4-1/2 Inch EUE Tubing
4-1/2" OD External Upset End (EUE) nonalloy steel tubing for oil well production, with 8-round threads for easy makeup. Meets HTS 7306.29.60 as standard iron/nonalloy drilling tubing. Commonly used in vertical and deviated wells.
API 5CT N80 Casing Tubing
Seamless tubing made from nonalloy steel, conforming to API 5CT specifications for N80 grade, used in oil and gas wells to line the borehole and protect against collapse. It falls under HTS 7306.29.60 as it is iron or nonalloy steel tubing specifically for drilling applications. The tubing's strength and corrosion resistance make it ideal for intermediate casing strings.
J55 Oil Well Tubing
Welded nonalloy steel tubing graded J55 per API standards, deployed in production zones of oil wells to convey hydrocarbons to the surface. Classified under HTS 7306.29.60 for its role as drilling tubing of iron or nonalloy steel. Features threaded connections for secure well integrity.
K55 Production Tubing
Nonalloy steel K55 grade tubing for oil and gas production strings, providing pressure containment and fluid flow in wellbores. It meets HTS 7306.29.60 criteria as iron/nonalloy steel tubing used in drilling operations. Corrosion-resistant coating options enhance longevity.
L80 Type 9 Cr13 Casing
Nonalloy steel L80 Type 9 casing with Cr13 martensitic composition for sour service environments in oil/gas drilling. Fits HTS 7306.29.60 as iron/nonalloy tubing despite chromium content under alloy thresholds. Used to isolate formations in corrosive wells.
P110 High Pressure Tubing
