1. Discover the superior material quality of the API 7-1 Non-Magnetic Drill Collar! Our Slick Drill Collar, with an outer diameter ranging from 79.4mm to 279.4mm, is crafted from top-grade 4145H/4145H mod steel, or select our non-magnetic option for unparalleled performance.
2. Standard Excellence: Our drill collars adhere strictly to the rigorous API 7-1 and NS-1 standards, ensuring you receive only the best.
A. Slick Drill Collar
Note: The primary function of our drill collar is to supply weight to the drill bit, keeping the drill pipe in tension for optimal performance. Especially designed for stability, our drill collars are
crafted with precision to keep the drill bit perfectly centralized and maintain a steady hole track, thanks to their substantial rigidity. Manufactured in strict accordance with API Spec7-1
and SY5411 standards, they meet the highest industry benchmarks.
B. Spiral Drill Collar
Note: Our Spiral Drill Collar is engineered to minimize contact with the borehole, effectively preventing bit sticking due to differential pressure. Each piece is manufactured under the exacting standards of API Spec7-1 and
SY5144, ensuring superior quality and reliability.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: The addition of elevator and slip grooves on the box thread face of both slick and spiral drill collars provides exceptional lifting capability and enhanced safety when tripping out.
Our technical parameters for these grooves comply fully with API SPEC7-1 standards. Optional hardbanding can be requested to suit specific customer needs.
D. Non-magnetic Drill Collar
Experience the advanced treatment of our non-magnetic drill collar, featuring a cold-rolled finish on both ID and OD surfaces. This unique process fortifies the structure, delivering superior stress, corrosion, and cracking resistance, while massively enhancing mechanical performance.
Premium Quality API 7-1 NS-1 Non-Magnetic Drill Collar
Technical Specifications for API 7-1 Non-Magnetic Drill Collar: Our Slick Drill Collar, with an OD ranging from 79.4mm to 279.4mm, is crafted to meet your highest drilling standards.
