Product Description

DRILL COLLAR

 

 

 

 

 

 

1. Premium Material of API 7-1 Non-Magnetic Drill Collar: Our Slick Drill Collar ranges from OD 79.4mm to 279.4mm, crafted from top-tier 4145H/4145H mod or a superior Non-magnetic alloy.
2. Industry Standards: Compliant with API 7-1 and NS-1 standards, ensuring reliability and performance.
A. Sleek and Sturdy Slick Drill Collar
Note: Designed primarily to transmit substantial weight to the drill bit, the drill collar keeps the drill pipe in a state of tension. Particularly, our drill collar is engineered to
maintain the drill bit centralization and optimal hole trajectory due to its exceptional rigidity. Manufactured in strict adherence to API Spec7-1 and
SY5411 standards, our drill collars are the epitome of precision engineering.
B. Efficient Spiral Drill Collar
Note: Our spiral drill collar is expertly crafted to minimize contact with the borehole, thereby significantly reducing the risk of bit sticking from differential
pressure. These drill collars are produced strictly following API Spec7-1 and SY5144 standards, ensuring superior quality and performance.
C. Advanced Spiral Drill Collar With Elevator and Slip Groove
Note: The incorporation of elevator and slip grooves on the box thread face, whether on slick or spiral drill collars, facilitates efficient lifting
and safety operations during trips out. These grooves adhere to API SPEC7-1 standards, with optional hardbanding available upon customer request.
D. Cutting-edge Non-magnetic Drill Collar
Our unique cold rolled finish on both the ID and OD surfaces, combined with an innovative technical process, enhances structural integrity, ensuring optimal resistance to stress, corrosion, and cracking, and significantly boosts mechanical performance.
High-Quality API 7-1 NS-1 Certified Non-Magnetic Drill Collar
Specifications for our API 7-1 Non-Magnetic Slick Drill Collar: Available in sizes ranging from OD 79.4mm to 279.4mm, offering versatility and precision.
