A. Slick Drill Collar
Note: The drill collar is an essential component, designed to provide sufficient bit weight to the drill bit, ensuring the drill pipe remains under tension. Especially crucial for maintaining stability and efficiency in operations, this drill collar can
keep the drill bit perfectly centralized and ensure accurate hole tracking through its robust rigidity. Our drill collars are crafted following the rigorous API Spec7-1 and
SY5411 standards to guarantee top-notch quality.
B. Spiral Drill Collar
Note: Our spiral drill collar is ingeniously designed to minimize contact with the hole, effectively preventing bit sticking from differential
pressure. Each drill collar is meticulously manufactured in strict accordance with API Spec7-1 and Standard SY5144, underscoring our dedication to superior quality.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: Featuring elevator groove and slip groove expertly crafted on the box thread face of both slick and spiral drill collars, this design facilitates safe lifting
and functions as a reliable safety slip when tripping out. The technical parameters for these grooves strictly adhere to API SPEC7-1 standards. Additionally, hardbanding can be applied upon customers' requests, offering enhanced durability.
D. Non-magnetic Drill Collar
Utilizing an as-cold-rolled finish on both ID and OD surfaces, our unique technical process fortifies the structure, providing exceptional resistance to stress, corrosion, and cracking, while significantly enhancing mechanical performance.
High Quality API 7-1 NS-1 Non-Magnetic Drill Collar
Specifications for API 7-1 Non-Magnetic Drill Collar: Our Slick Drill Collar ranges OD from 79.4mm to 279.4mm, epitomizing precision engineering and superior performance.
