Product Description

DRILL COLLAR

 

 

 

 

 

 

1. Material of API 7-1 Non-Magnetic Drill Collar Slick Drill Collar OD 79.4mm to 279.4mm: Crafted with precision using 4145H/4145H mod or Non-magnetic materials, ensuring superior quality and performance.
2. Standard: API7-1, NS-1. Our standards set the benchmark for quality and reliability in the industry.
A. Slick Drill Collar
Note: The drill collar serves as a crucial component, primarily designed to impart substantial bit weight to the drill bit, maintaining drill pipe tension seamlessly. Its role is especially vital as it
ensures the drill bit remains centralized while guiding the hole track with remarkable rigidity. Each drill collar is manufactured with unwavering adherence to API Spec7-1 and
SY5411 standards, embodying precision and excellence.
B. Spiral Drill Collar
Note: Designed to minimize contact with the borehole, the spiral drill collar effectively prevents differential pressure sticking, enhancing drilling efficiency. Our drill collars are crafted following the stringent
guidelines of API Spec7-1 and Standard SY5144, ensuring unparalleled quality and reliability.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: The strategically engineered elevator groove and slip groove located on the box thread face of slick or spiral drill collars serve as a practical lifting aid and safety feature when tripping out. These
grooves meet the rigorous technical parameters as defined by API SPEC7-1. For enhanced functionality, hardbanding is available at our esteemed customer's request, tailored to meet specific needs.
D. Non-magnetic Drill Collar
The drill collar's cold-rolled finish on both ID and OD surfaces, combined with an exclusive technical process, fortifies the structure. This ensures optimal resistance to stress, corrosion, and cracking while
significantly enhancing mechanical performance. Our high-quality API 7-1 NS-1 Non-Magnetic Drill Collars are the epitome of strength and durability.
Specifications for API 7-1 Non-Magnetic Drill Collar Slick Drill Collar OD 79.4mm to 279.4mm are crafted to perfection, meeting and exceeding industry standards.
