It is available in sizes ranging from 3-1/8 to 11 inches, with options for slick, spiral, or non-magnetic variants to suit different operational needs. Manufactured from AISI 4145H modified steel, the drill collar undergoes full-length heat treatment to meet or exceed API Spec 7-1 mechanical property requirements, ensuring durability and performance in demanding downhole conditions.
Each drill collar is trepanned and drifted to API Spec 7-1, with cold-rolled thread roots and elevator recess upper radii to enhance fatigue life and resist crack initiation. Connections are phosphate-coated or copper-plated for improved corrosion resistance, and optional slip and elevator recesses are available to improve handling efficiency. The material and process traceability is maintained throughout manufacturing, with serial numbers die-stamped on each bar body for identification.
This product is primarily used by drilling contractors and oilfield service companies operating in directional or horizontal wells, where non-magnetic properties are critical for accurate MWD/LWD surveys. Buyers should confirm the collar’s compatibility with their drilling assembly and verify its non-magnetic properties, as these are essential for maintaining sensor accuracy. Bulk shipments are typically supplied with steel, cast steel, or plastic thread protectors to prevent damage during transit from China.

Before placing an order, verify the non-magnetic properties of the drill collar to ensure compatibility with your MWD/LWD tools, as these are critical for accurate wellbore surveys. Request the supplier’s API Spec 7-1 compliance documentation, including material test reports and inspection certificates, to confirm the collar meets your technical requirements. Check the hardness and impact strength values against your project’s specifications, as these properties are essential for performance in demanding downhole conditions.
Discuss logistics details, such as packaging, thread protection, and shipping methods for bulk orders from China. Clarify Incoterms, such as FOB or CIF, to determine responsibility for freight, insurance, and customs clearance. Lead times may vary based on production schedules, so request a timeline for delivery to your specified port or facility. Payment terms, such as TT or LC, should be agreed upon in advance to ensure a smooth transaction.
Upon receipt, inspect the drill collar for signs of damage, corrosion, or dimensional inaccuracies, and verify its compliance with the supplier’s specifications. Request a third-party inspection if required by your quality assurance protocols. Ensure all documentation, including API compliance certificates and inspection reports, is complete and accurate. For critical applications, consider witnessing the manufacturing or testing processes to validate the component’s integrity and performance.
