Описание:
Drill collars are heavy-walled tubular components used in the drill string to provide weight on bit during drilling operations. These components are manufactured from high-strength alloy steel. They help maintain directional control and improve drilling stability. The collars are designed to withstand high torque and compressive loads. They are used in both vertical and directional drilling. The product is available in multiple sizes and configurations. It is suitable for onshore and offshore applications.

Non-Magnetic Drill Collars
Technical Summary
As you drill in areas closer to the earth's magnetic poles, it is essential to use a non-magnetic drill collar. Our non-mag drill collars offer strength and hardness while neutralizing magnetic inference. Compatible with standard drill string tools and stabilizers, our non mag drill collars are manufactured to API Spec 7-1. Inventory includes:
- Slick
- Flex
- Spiral
- Pony
We treat our non-mag material ID with a shot peening operation to compress the inside diameter which prevents stress corrosion while drilling in H2S environments.
- Resistant to stress corrosion in sour gas environments
- Compatible with standard drill string tools and stablizers
- Spiraling available on request

Steel Drill Collars
Used to add weight to the bit and stiffness to bottom hole assembly, our Drill Collars are an invaluable downhole tool.
To keep you drilling in the right direction, run our Drill Collars in combination with our Stabilizers to resist bucking. Manufactured from an AISI 4145H modified heat treated alloy steel, our strict quality assurance guidelines assure metallurgical integrity of each and every bar.
Our Drill Collar bars are batch or continuous line heat treated and have both cold-worked and Phosphate coated connections.
