Product Description

Introducing our premium DRILL COLLAR, designed to ensure unparalleled drilling stability and efficiency.

 

 

 

 

 

 

1. Material of API 7-1 Non-Magnetic Drill Collar, Slick Drill Collar OD ranging from 79.4mm to 279.4mm: crafted from high-quality 4145H/4145H mod or advanced Non-magnetic materials for superior performance.
2. Built to rigorous standards: API7-1, NS-1, ensuring exceptional reliability and safety in every use.
A. Slick Drill Collar: Engineered for optimal weight distribution and alignment during drilling operations.
Note: The drill collar is primarily utilized to impart the necessary weight on the drill bit, keeping the drill pipe under tension for improved drilling precision. Specially designed drill collars can
maintain the centralization of the drill bit and enhance hole tracking due to their robust rigidity. Each drill collar is manufactured with strict adherence to API Spec7-1 and
SY5411 standards, ensuring unmatched quality.
B. Spiral Drill Collar: Innovatively designed to minimize contact area with the hole, effectively reducing the risk of bit sticking caused by differential
pressure. Manufactured with precision according to API Spec7-1 and Standard SY5144, these collars offer superior performance.
pressure, and expertly crafted following the stringent API Spec7-1 and SY5144 standards for premium quality and reliability.
C. Spiral Drill Collar With Elevator Groove And Slip Groove: Enhanced with
Note: Elevator groove and slip groove crafted on the box thread face of either slick or spiral drill collars serve as a lifting sub and safety slip during tripping out. These technical parameters adhere strictly to API SPEC7-1. Hardbanding can be added upon customer request for added durability.
sub and safety slip functionality during tripping out. Technical parameters conform to API SPEC7-1 standards, with optional hardbanding available to meet customer specifications.
D. Non-magnetic Drill Collar: Crafted with precision engineering to offer unparalleled performance.
The as-cold-rolled finish on both ID and OD surfaces, using a unique technical process, strengthens the structure. It ensures optimal resistance to stress, corrosion, and cracking, significantly enhancing mechanical performance.
High-Quality API 7-1 NS-1 Non-Magnetic Drill Collar: Designed to meet the highest industry standards, offering outstanding durability.
