1. Exquisite Material Selection for API 7-1 Non-Magnetic Drill Collar Slick Drill Collar OD 79.4mm to 279.4mm: Choose between robust 4145H/4145H mod or Non-magnetic for superior performance.
2. Uncompromising Standards: Compliant with API7-1, NS-1 for assured quality and safety.
A. Slick Drill Collar
Note: Our drill collar is expertly designed to impart optimal bit weight to the drill bit, ensuring that the drill pipe remains under tension. This precision engineering allows the drill collar to
maintain the drill bit's centralization and stabilize the hole track through its inherent large rigidity. Manufactured with stringent adherence to API Spec7-1 and
SY5411 standards, delivering excellence with every drill.
B. Spiral Drill Collar
Note: The Spiral drill collar is ingeniously crafted to lessen contact with the hole, efficiently preventing bit sticking due to differential
pressure. These collars are meticulously manufactured to meet the rigorous API Spec7-1 and Standard SY5144.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: Our expertly crafted elevator groove and slip groove on the box thread face of either slick or spiral drill collars serve as a reliable lifting
sub and safety slip during trips out. These grooves are designed according to API SPEC7-1 standards, with optional Hardbanding to cater to specific customer needs.
D. Non-magnetic Drill Collar
The cold-rolled finish on both ID and OD surfaces, combined with a unique technical process, fortifies the structure, enhancing the tool's resistance to stress, corrosion, and cracking. This ensures superior mechanical performance.
High-Quality API 7-1 NS-1 Non-Magnetic Drill Collar
Specifications: Choose from a range of API 7-1 Non-Magnetic Drill Collar Slick Drill Collar OD options, 79.4mm to 279.4mm, for tailored drilling solutions.
