API Drill Pipe | Drill Pipe Supplier

WE EQUIP THE INDUSTRY.™

We Equip the Industry with Drill Pipe that Delivers More Value Per Foot

Operators choose TSC Drill Pipe because our products deliver proven, measurable performance in the field. Our drill pipe is engineered to outperform and outlast, reducing the cost per foot drilled (or lower total cost of ownership) run after run, well after well.

We start with heavier-wall, high-integrity material and manufacture under some of the tightest quality controls in the industry. Our API drill pipe consistently exceeds API specifications, including 95%+ remaining body wall retention, verified through extensive inspection data and full traceability.

From high-torque shale plays to offshore drill pipe operations, TSC drill pipe has a proven global track record in the world's most demanding wells. We offer API and premium connections, specialized drill pipe grades, and tailored solutions engineered to give operators a measurable performance advantage.

When reliability matters, and cost per foot drilled matters even more, operators trust TSC.

Build Your Own Drill Pipe >

Built with Integrity. Proven in the Field.

At Texas Steel Conversion, Inc., integrity is more than a principle, it's the standard that guides every decision, every process, and every joint we manufacture. For decades, we have earned the trust of operators as a trusted drill pipe supplier, upholding uncompromising quality, applying rigorous controls, and advancing industry-leading practices that ensure consistent, reliable performance downhole.

From raw steel to final inspection, our work reflects a clear purpose: manufacture API drill pipe that operators can trust at every depth, in every basin, under every condition.

Frequently Asked Questions

How do double-shoulder connections increase torsional capacity?

Double-shoulder connections feature an internal secondary torque shoulder in addition to the primary external shoulder. This design increases the mechanical contact surface area, allowing higher makeup torque capacity, reducing connection yielding, and improving fatigue resistance during extended-reach drilling (ERD) and deepwater operations.

How does sour service drill pipe differ from standard API grades?

Sour service drill pipe undergoes specialized controlled-yield heat treatment and strict chemical composition limits (low sulfur and phosphorus content). This metallurgical control enhances resistance to Hydrogen-Induced Cracking (HIC) and Sulfide Stress Cracking (SSC) in aggressive downhole conditions containing wet H2S.

What friction welding quality control standards are performed during manufacturing?

All inertia friction welds undergo 100 percent non-destructive testing, including ultrasonic wall testing and wet magnetic particle inspection. Welds are post-weld heat-treated to relieve residual stress and restore homogeneous grain structures across the weld transition zone.

What minimum lead times apply to custom drill pipe manufacturing?

Standard API sizes and grades are maintained in yard inventory for immediate dispatch. Custom orders requiring proprietary high-torque threads, non-standard wall thicknesses, or specialized sour service heat treatment carry lead times ranging from 4 to 12 weeks based on steel mill allocation.

Can drill pipe be delivered with factory-applied coatings and hardbanding?

Yes. Drill pipe processing integrates in-house application of casing-friendly hardbanding alloys to tool joint wear pads and internal plastic coating (IPC) to the pipe body ID prior to final inspection and yard delivery.
