1. Unleashing advanced technology: Material of the cutting-edge API 7-1 Non-Magnetic Drill Collar Slick Drill Collar ranges from OD 79.4mm to 279.4mm, crafted with precision from 4145H/4145H mod or superior Non-magnetic materials.
2. Adhering to the highest standards: Compliant with rigorous API7-1 and NS-1 standards.
A. Slick Drill Collar
Note: The primary function of a drill collar is to impart essential weight to the drill bit, ensuring the drill pipe remains taut. Particularly, the drill collar excels at
maintaining precise center alignment of the drill bit and the hole track through its robust rigidity. Crafted meticulously to the exacting API Spec7-1 and
SY5411 standard to guarantee superior performance.
B. Spiral Drill Collar
Note: The Spiral Drill Collar is ingeniously designed to minimize contact with the borehole, effectively preventing bit sticking due to differential
pressure. These drill collars are manufactured with exacting standards as per API Spec7-1 and SY5144, ensuring peak performance.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: Featuring an elevator groove and slip groove on the box thread face, both slick and spiral drill collars can function as unparalleled lifting
substitutes and safeguard slips when tripping out. The elevator and slip groove parameters comply fully with API SPEC7-1. Optional hardbanding is available to meet customer specifications.
D. Non-magnetic Drill Collar
Benefit from the as-cold-rolled finish on both ID and OD surfaces, achieved through a unique technical process that fortifies structure, ensuring maximum resistance to stress, corrosion, and cracking. This elevates the mechanical performance to new heights.
Premium Quality Assured: API 7-1 NS-1 Non-Magnetic Drill Collar
