Product Description

DRILL COLLAR

 

 

1. Materials Used: Our API 7-1 Non-Magnetic Drill Collar and Slick Drill Collar range from OD 79.4mm to 279.4mm and are crafted from either 4145H/4145H mod or premium non-magnetic materials.
2. Adherence to Standards: Our drill collars meet the stringent requirements of API7-1 and NS-1, ensuring top-tier quality and reliability.
A. Slick Drill Collar
Note: The drill collar is essential for providing the necessary bit weight to the drill bit, ensuring the drill pipe remains in tension. Specifically, drill collars are engineered to
maintain the drill bit's centralization and stabilize the hole trajectory with their substantial rigidity. Manufactured with precision from API Spec7-1 and
SY5411 standards, they exemplify excellence.
B. Spiral Drill Collar
Note: Our innovative Spiral Drill Collar minimizes contact area with the borehole, significantly reducing the risk of bit sticking due to differential
pressure. Fabricated in strict compliance with API Spec7-1 and Standard SY5144, these collars promise superior performance.
C. Spiral Drill Collar with Elevator Groove and Slip Groove
Note: Designed for versatility, the elevator groove and slip groove are incorporated onto the box thread face of both slick and spiral drill collars. This design enables
easy lifting and acts as a safety slip when tripping out. All technical parameters adhere to API SPEC7-1, and hardbanding options are available per customer requests.
D. Non-magnetic Drill Collar
Our precision-engineered process delivers a cold rolled finish on both ID and OD surfaces, enhancing structural integrity and providing robust resistance against stress, corrosion, and cracking, ensuring superior mechanical performance.
Premium Quality API 7-1 NS-1 Non-Magnetic Drill Collar
Comprehensive Specifications: Our API 7-1 Non-Magnetic Drill Collar and Slick Drill Collar are available from OD 79.4mm to 279.4mm, meticulously designed for optimal performance in demanding environments.
