Heavy Duty Gas Free Forging Offshore Drilling Spindle For Oil

The Heavy-Duty Offshore Drilling Spindle Free Forging is a precision-engineered forged component designed for high-load rotary systems in offshore oil and gas exploration. It functions as a key element in top drives, rotary tables, and drilling heads, transferring torque and axial load in critical downhole operations.

Forged from high-strength alloy steels such as 42CrMo4, this spindle offers exceptional fatigue resistance, torsional strength, and dimensional stability under extreme pressures, vibration, and corrosive environments. The free forging process ensures a directional grain structure optimized for high mechanical stress and long-term service life.

Key Features:

• Open-die forged for high-integrity performance in rotary drilling systems

• Customized dimensions: splines, threads, shoulders, and flange interfaces

• Heat treated (Q+T) for maximum strength and toughness

• 100% Ultrasonic Tested (UT) and Magnetic Particle Inspected (MPI)

• Optional Inconel cladding, anti-corrosion coating, or stress-relieving available

Applications:

• Offshore drilling rigs, land-based drilling systems

• Top drives, kelly drives, rotary tables, and mud motors

• Ideal for high-torque, high-shock, cyclic loading in deep well drilling

 
The steel forgings production flow:
Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
