OCTG Pipe Types
Comprehensive guide to oil country tubular goods including casing, tubing, drill pipe, and specialty pipe products used in drilling and production operations.
Casing
Structural pipe installed in wellbores to maintain integrity and isolate formations during drilling and production.
Tubing
Production conduit for transporting hydrocarbons from reservoir to surface with various sizes and pressure ratings.
Drill Pipe
Rotating pipe used to transmit drilling fluid and torque from surface to the bit during drilling operations.
Heavy-Weight Drill Pipe (HWDP)
Intermediate weight tubular providing transition between drill pipe and drill collars for weight-on-bit control.
Drill Collars
Heavy-walled tubulars providing weight-on-bit and maintaining directional control in the bottom hole assembly.
Line Pipe
Pipeline-grade tubulars for transporting oil, gas, and water from wellhead to processing and distribution facilities.
Conductor Pipe
Large diameter structural pipe installed at wellhead to support subsequent casing strings and BOP equipment.
Welded Steel Pipe
Electric resistance welded and submerged arc welded pipe for casing, line pipe, and structural applications.
Seamless Pipe
Hot-rolled seamless tubulars manufactured without welds for critical pressure and structural applications.
