1. Premium Material Selection for API 7-1 Non-Magnetic Drill Collar: Choose between 4145H/4145H mod or a Non-magnetic option, with available outer diameters ranging from 79.4mm to 279.4mm.
2. Industry Standards: Complies with API7-1 and NS-1 standards for guaranteed performance and reliability.
A. Slick Drill Collar
Note: The primary function of a drill collar is to apply the necessary bit weight to the drill bit in order to keep the drill pipe under tension. Notably, the drill collar is engineered to
centralize the drill bit and maintain the integrity of the hole trajectory due to its substantial rigidity. These drill collars are meticulously manufactured in accordance with API Spec7-1 and
SY5411 standards, assuring top-tier quality.
B. Spiral Drill Collar
Note: The spiral design of this drill collar is specifically crafted to minimize contact with the borehole, thereby effectively preventing bit sticking caused by differential
pressure issues. These drill collars are produced with strict adherence to API Spec7-1 and Standard SY5144, ensuring superior performance.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: The incorporation of an elevator groove and slip groove on the box thread face of either slick or spiral drill collars serves as a lifting
substitute and safety slip for tripping operations. The groove specifications are precisely aligned with API SPEC7-1 standards. Optional hardbanding is available upon customer request.
D. Non-magnetic Drill Collar
Benefit from the as-cold rolled finish on both the inner and outer surfaces, enhanced through a distinctive technical process that fortifies the structure, offering exceptional resistance to stress, corrosion, and cracking. The mechanical performance is significantly elevated.
Explore our High-Quality API 7-1 NS-1 Non-Magnetic Drill Collar, designed for rigorous demands.
Specifications for API 7-1 Non-Magnetic Drill Collar: Our slick drill collars are available in diameters from 79.4mm to 279.4mm, catering to diverse drilling requirements.
