T Thread

The T Thread (T-type thread) series drill pipe is a type of high-strength drill pipe widely used in fields such as petroleum, natural gas, geological exploration, and deep-hole drilling. Its core feature is the adoption of a trapezoidal thread design, which offers high load-bearing capacity, excellent torsional resistance, and good sealing performance. It is suitable for drilling with high torque, deep holes, and complex formations.

Main features

High strength & high rigidity: alloy steel (such as S135, G105) is used to adapt to deep hole and ultra-deep hole operation.

Optimized thread design: The trapezoidal thread provides higher tensile and torsional resistance.

Good sealing: some models have metal sealing ring to reduce mud leakage.

Wear and corrosion resistant: can be chrome plating, phosphating or special coating treatment to extend the life.

Strong compatibility: some specifications can be mixed with API drill pipe to improve the versatility of equipment.
