Product Description

DRILL COLLAR

 

 

1. Exquisite Material for API 7-1 Non-Magnetic Drill Collar: Choose from premium 4145H/4145H mod or superior Non-magnetic material. Available in a versatile range of sizes from OD 79.4mm to 279.4mm.
2. Industry Standards: Meticulously crafted to adhere to API7-1 and NS-1 standards.
A. Slick Drill Collar
Note: The drill collar serves the crucial purpose of delivering bit weight to the drill bit, ensuring that the drill pipe remains under tension. It is expertly engineered to
maintain drill bit centralization and guide the hole track with its superior rigidity. Each drill collar is manufactured in strict accordance with API Spec7-1 and
SY5411 standards, ensuring unmatched quality and reliability.
B. Spiral Drill Collar
Note: The Spiral drill collar is ingeniously designed to minimize contact area with the hole, thereby effectively preventing bit sticking due to differential
pressure. Our drill collars are crafted with precision, strictly following API Spec7-1 and SY5144 standards for exceptional performance.
C. Spiral Drill Collar with Elevator Groove and Slip Groove
Note: Incorporating elevator and slip grooves on the box thread face of either slick or spiral drill collars facilitates lifting and provides an added layer of safety
as a slip when tripping out. The technical specifications comply with API SPEC7-1. Additionally, hardbanding is available upon customer request.
D. Non-Magnetic Drill Collar
Our non-magnetic drill collars are crafted with a cold-rolled finish on both ID and OD surfaces. This unique technical process enhances structural integrity and ensures exceptional resistance to stress, corrosion, and cracking, thereby significantly boosting mechanical performance.
High-Quality API 7-1 NS-1 Non-Magnetic Drill Collar
Specifications: API 7-1 Non-Magnetic Drill Collar features are available with Slick Drill Collar sizes ranging from OD 79.4mm to 279.4mm, meeting the highest quality standards.
