Products classified under HTS 8430.49.80.10
Rotary Swivel for Oil Rig Drill String
A rotary swivel connects the top drive or kelly to the drilling hose, allowing rotation while permitting mud flow in oil well rotary drilling. It is included in HTS 8430.49.8010 as essential rotary machinery for oil and gas field boring operations.
Independent Rotary Table for Offshore Rigs
Independent rotary tables operate without kelly dependency on offshore oil platforms, offering backup rotation for drilling strings. Fits HTS 8430.49.8010 as rotary machinery for oil and gas field boring.
Variable Frequency Drive Rotary for Oil Rigs
VFD rotary systems control motor speed for precise rotation in oil rig drilling, optimizing torque for hard rock formations. HTS 8430.49.8010 covers this rotary boring tech for oil/gas fields.
Rotary Table for Oil Well Drilling Rig
A rotary table is a mechanical device mounted on the drill floor of an oil rig that provides torque to the drill string through the kelly or top drive. It falls under HTS 8430.49.8010 as rotary boring machinery specifically for oil well and gas field drilling, enabling the rotational force necessary for penetrating earth layers to extract hydrocarbons.
Kelly Drive Bushing for Rotary Gas Drilling
The kelly drive bushing connects the kelly to the rotary table, transmitting rotary motion to the drill string in gas field operations. Classified under HTS 8430.49.8010 for its role in rotary boring machinery dedicated to oil and gas well drilling.
Master Bushing Adapter for Rotary Drilling
Master bushing adapters fit into rotary tables to grip kellys or pipes during oil well rotary boring, ensuring secure torque transfer. Falls under HTS 8430.49.8010 for rotary-specific oil and gas field drilling machinery.
Top Drive Rotary System for Gas Wells
A top drive rotary system replaces the kelly-rotary table setup, directly rotating the drill string from the derrick top in gas well drilling. Classified in HTS 8430.49.8010 as advanced rotary boring machinery for oil and gas fields.
Rotary Power Head for Oil Exploration Drilling
Rotary power heads are hydraulic or electric driven rotary units mounted on drills for oil exploration boring, providing downhole rotation. Under HTS 8430.49.8010 for rotary oil well and gas field machinery.
Hydraulic Rotary Drive Unit for Gas Fields
Hydraulic rotary drive units power drill string rotation via fluid pressure in gas field drilling operations, integral to rotary boring rigs. Classified under HTS 8430.49.8010 for oil/gas rotary machinery.
Rotary Spider Assembly for Drilling Pipes
Rotary spider assemblies grip and suspend drill pipes in the rotary table during oil well boring, preventing string slippage. Included in HTS 8430.49.8010 as rotary components for gas field drilling.
