Product Description

DRILL COLLAR

 

 

 

 

 

 

1. Material of API 7-1 Non-Magnetic Drill Collar Slick Drill Collar OD 79.4mm to 279.4mm: Crafted meticulously from 4145H/4145H mod or Non-magnetic materials, ensuring superior strength and durability for exceptional drilling performance.
2. Standard: API7-1, NS-1. Our products adhere to the highest industry standards, guaranteeing reliability and consistency across all applications.
A. Slick Drill Collar
Note: The drill collar is chiefly employed to supply the necessary bit weight to the drill bit, maintaining the drill pipe in a state of tension. This critical component is designed to
keep the drill bit centralized and ensure an accurate hole track through its large rigidity. These drill collars are meticulously manufactured in strict compliance with API Spec7-1 and
SY5411 standards, reflecting our commitment to quality and precision.
B. Spiral Drill Collar
Note: The spiral drill collar is engineered to minimize contact with the hole, effectively preventing bit sticking due to differential pressure. Each drill collar is crafted in strict
accordance with API Spec7-1 and Standard SY5144, emphasizing our dedication to excellence and innovation.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: Featuring elevator grooves and slip grooves on the box thread face of both slick and spiral drill collars, these designs serve as lifting subs and ensure safety when tripping out.
The technical parameters for elevator and slip grooves adhere to API SPEC7-1 standards. Additionally, hardbanding is available at the customer's request, providing enhanced wear resistance.
D. Non-magnetic Drill Collar
The cold-rolled finish on both the ID and OD surfaces, achieved through a unique technical process, fortifies the structure and guarantees optimal resistance to stress, corrosion, and cracking, 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 79.4mm to 279.4mm: Our drill collars are designed to meet rigorous specifications, ensuring robust performance across various drilling environments.
