GPE Oil Machinery Co., Ltd - Drill Collar

The Drill Collar is a fundamental component in the BHA (Bottom Hole Assembly) used for drilling. It provides weight on the bit and ensures the drillstring remains in tension. GPE Oil Machinery Co., Ltd offers a high-quality Drill Collar that has been approved by the NS-1 certification.

Our Drill Collar is manufactured from 4145H modified quenched and tempered steel, following strict metallurgical specifications. This ensures that the full length heat treating process produces a consistent maximum depth of hardness.

• Hardness range of 285 to 341 BHN


• Charpy impact value of 40 ft-lbs guaranteed at evenly distributed 16 points in any sections at room temperature


• Connections completed (phosphate coated) to protect them from the elements and prevent galling upon initial make-up
