DRILL COLLAR

 

 

1. Exceptional Material for API 7-1 Non-Magnetic Drill Collar Slick Drill Collar ranging from OD 79.4mm to 279.4mm: Primarily crafted from 4145H/4145H mod or premium Non-magnetic material.
2. Standards Adhered: Crafted with precision to meet API7-1, NS-1 standards.
A. Slick Drill Collar
Note: The drill collar is fundamentally utilized to impart ideal bit weight to the drill bit, ensuring that the drill pipe remains under tension. This is crucial in drilling operations as the drill collar is designed to
maintain the centralization of the drill bit and guide the hole trajectory with its significant rigidity. These drill collars are meticulously manufactured in strict accordance with API Spec7-1 and
SY5411 standards, guaranteeing superior performance.
B. Spiral Drill Collar
Note: The spiral drill collar is engineered to minimize the contact area with the hole, effectively preventing bit sticking due to differential
pressure conditions. These drill collars are precisely crafted following API Spec7-1 and Standard SY5144, ensuring reliable performance.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: Featuring elevator and slip grooves on the box thread face of both slick and spiral drill collars, these can function as lifting
subs and safety slips during trip-out operations. The technical parameters for these features adhere to API SPEC7-1, with optional hardbanding available upon customer request, enhancing their functionality.
D. Non-magnetic Drill Collar
Crafted with a cold-rolled finish on both ID and OD surfaces, this unique technical process fortifies the structure, ensuring the tools possess outstanding resistance to stress, corrosion, and cracking. The mechanical performance of these collars is significantly enhanced.
Premium Quality API 7-1 NS-1 Non-Magnetic Drill Collar
