The API oilfield non magnetic drill collar is positioned between the drill pipe and the bit in the drill stem, providing the necessary weight on the bit to enable effective drilling. This model is manufactured from AISI 4145H modified steel, delivered in an as rolled surface finish with optional finishes available. It undergoes full length heat treatment to meet API Spec 7-1 mechanical property requirements, including a guaranteed Brinell hardness range of 285 to 341 and a Charpy V notch minimum impact strength of 40 ft-lb at 70°F one inch below the surface.
Material traceability is maintained from raw steel receipt through to final manufacturing, with serial numbers die stamped on each bar body. The product features cold rolled thread roots and elevator recess upper radii to enhance fatigue life by minimizing crack initiation. Connections are phosphate coated or copper plated for corrosion resistance, while optional slip and elevator recesses improve handling efficiency and safety. Thread protectors in steel, cast steel, or plastic steel are offered as standard accessories.
Non magnetic drill collars are essential in directional drilling operations where magnetic interference must be minimized. Buyers typically include oil and gas exploration companies, drilling contractors, and service providers requiring reliable downhole tools. Trade terms such as MOQ, lead time, and incoterms should be confirmed directly with the supplier to align with project requirements.

Before placing an order, verify the exact dimensions and material specifications of the non magnetic drill collar to ensure compatibility with your drilling assembly. Confirm the Brinell hardness range and Charpy impact strength values, as these are critical for downhole performance under stress. Request documentation of the heat treatment process and material certifications to validate compliance with API Spec 7-1.
Clarify logistics details such as lead time, preferred incoterms (e.g., FOB or CIF), and packaging standards for thread protectors. Non magnetic drill collars are typically shipped as individual joints or in bundled sets, so confirm the packaging method and any additional handling requirements. Ensure the supplier can accommodate your project timeline, especially for large or urgent orders.
Quality checks should include ultrasonic inspection of the full body to detect internal flaws, as well as visual dimensional verification. Inspect the phosphate coating or copper plating on connections for uniformity and corrosion resistance. Request third party inspection reports if available, and confirm that serial numbers are die stamped for traceability. Proper documentation, including mill test certificates and API compliance records, should accompany the shipment.
