Hard rock drilling puts extreme torque and vibration on every joint in the drill string. Selecting the right pipe wall thickness, steel grade and tool-joint thread is the difference between a productive shift and costly downtime.
At Sri Andavar Engineering Works, we fabricate high-tensile drill pipes with precision-threaded joints designed for deep-hole pressure and repeated make-up cycles.
What to check before ordering
- Formation hardness and expected depth
- Rig torque rating and connection standard
- Hardfacing needs on high-wear zones
