Product Description

DRILL COLLAR

 

 

1. Material: The sophisticated API 7-1 Non-Magnetic Drill Collar, ranging from an OD of 79.4mm to 279.4mm, is crafted using premium 4145H/4145H mod or state-of-the-art non-magnetic materials.
2. Standard: Adheres to the rigorous standards of API7-1 and NS-1.
A. Slick Drill Collar
Note: Primarily, the drill collar is indispensable for applying the necessary bit weight to the drill bit, ensuring the drill pipe stays in tension. This tool is crucial in maintaining the drill bit's precision alignment by its impressive rigidity.
The durability and reliability of our drill collars are ensured through strict manufacturing processes aligning with API Spec7-1 and SY5411 standard.
SY5411 standard.
B. Spiral Drill Collar
Note: To significantly reduce contact with the hole and prevent bit sticking caused by differential pressure, the spiral drill collar offers an innovative design solution.
Our drill collars are expertly crafted under the stringent guidelines of API Spec7-1 and Standard SY5144, ensuring superior performance.
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: The inclusion of an elevator groove and slip groove on the box thread face of both slick and spiral drill collars enhances their utility as lifting subs and safety slips during trips out.
These grooves conform to API SPEC7-1 technical parameters, with optional hardbanding available to meet customer preferences.
D. Non-magnetic Drill Collar
Our unique cold-rolled finish across both ID and OD surfaces is achieved through an advanced technical process, fortifying the structure and providing outstanding resistance to stress, corrosion, and cracking, thus significantly enhancing mechanical performance.
High Quality API 7-1 NS-1 Non-Magnetic Drill Collar
Specifications: Designed to meet the exacting API 7-1 standards, our Non-Magnetic Drill Collars range from an OD of 79.4mm to 279.4mm and promise unmatched performance and reliability.
