API Drill Collar

 

API Drill Collar, manufactured by GPE Oil Machinery Co., Ltd, is the essential component of the Bottom Hole Assembly (BHA) used in drilling operations. It provides weight on the bit and maintains tension in the drillstring.

 

Approved by the NS-1 certification, our drill collar is made from high-quality 4145H modified quenched and tempered steel. We strictly adhere to metallurgical specifications to ensure consistent hardness throughout the entire length of the collar.

 

Features

 

• Hardness range of 285 to 341 BHN


• Charpy impact value of 40 ft-lbs


• Guaranteed hardness and impact value at evenly distributed 16 points in any section at room temperature


• Connections completed with phosphate coating to protect against the elements and prevent galling


• Cold rolled thread roots on API and H-90 connections


 

 

Benefits

 

• Ensures efficient weight distribution on the bit for effective drilling


• Maintains tension in the drillstring, enhancing drilling performance


• Consistent hardness throughout the collar for reliable operation


• Phosphate coating on connections for protection and prevention of galling


• Cold rolled thread roots for secure and durable connections


 

 

Our API Drill Collar comes equipped with standard connections and includes pressed steel thread protectors for added protection.
