Product Description

DRILL COLLAR

 

 

 

 

 

 

1. Material of API 7-1 Non-Magnetic Drill Collar & Slick Drill Collar OD 79.4mm to 279.4mm: Crafted from either 4145H/4145H mod or Non-magnetic materials to ensure superior performance.
2. Standard: Adherence to API7-1, NS-1 standards guarantees exceptional quality and reliability.
A. Slick Drill Collar
Note: The drill collar is primarily employed to impart necessary bit weight to the drill bit, ensuring the drill pipe remains under tension. Furthermore, its design with superior rigidity aids in
maintaining the drill bit's centralization and precise hole trajectory. These collars are meticulously manufactured in full compliance with API Spec7-1 and
SY5411 standards for unparalleled performance.
B. Spiral Drill Collar
Note: The innovative spiral design of this drill collar minimizes contact with the hole, effectively preventing bit sticking due to differential
pressure. These collars are produced with strict adherence to API Spec7-1 and Standard SY5144, ensuring unmatched efficiency and reliability.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: The inclusion of elevator grooves and slip grooves on the box thread face of slick or spiral drill collars facilitates their use as lifting
subs and safety slips during tripping out. These refined technical parameters conform to API SPEC7-1. Optional hardbanding is available upon customer request for enhanced durability.
D. Non-magnetic Drill Collar
Crafted with a cold-rolled finish on both the ID and OD surfaces, the advanced 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 & Slick Drill Collar OD range from 79.4mm to 279.4mm, ensuring versatility and adaptability for various drilling needs.
