Import Bestar Steel Drill Pipe — Buy in wholesale FOB from Supplier in China

The Bestar Steel Drill Pipe is an API SPEC 5DP compliant tubular product manufactured for demanding drilling operations in oil, gas, and geothermal applications. It is produced in four standard API grades: E75, X95, G105, and S135, each designation referring to the minimum yield strength in ksi. The pipe body is forged from alloy steel and subjected to heat treatment processes including normalising and tempering to achieve the required mechanical properties. Connection ends are precision machined with tool joints, typically welded to the pipe body via friction welding, to ensure dimensional accuracy for make-and-break operations.

The material composition follows API 5DP requirements for drill pipe steel, with controlled carbon, manganese, and trace element content to balance strength, toughness, and weldability. Wall thickness, outer diameter, and upset geometry vary by grade and tool joint specification, with typical outer diameters ranging from 2-3/8 inch to 6-5/8 inch for standard sizes. Corrosion-resistant surface coatings, such as phosphate conversion coatings or proprietary thread compounds, are applied to extend service life in corrosive drilling mud environments. The product undergoes ultrasonic testing and magnetic particle inspection as standard quality verification steps.

This drill pipe serves contractors in surface drilling, directional drilling, and deep exploratory wells where fatigue resistance and connection integrity are critical. Buyers include oilfield service companies, drilling contractors, and mining operations requiring reliable downhole equipment. Trade terms should be confirmed directly with Bestar Steel Co., Ltd., including acceptable Incoterms, minimum order quantities, and lead times for specific grade and dimension combinations. The supplier is located in Changsha, Hunan Province, and buyers should verify current response availability and certification status before placing orders.

Bestar Steel Co., Ltd. is headquartered at No. 9 Xingfu Road, Yuhua District, Changsha 410116, in Hunan Province, China. The supplier carries an imported tier classification and a harbor trust tier designation. The response rate shown is 0.00 percent, with zero average response hours recorded, which indicates that direct communication channels may need to be established through alternative methods rather than platform messaging. No verified transaction history, third-party audit data, or certification expiry dates are present in the available profile information.

The listing presents itself as a manufacturer of API-compliant drill pipe with emphasis on grade variety and operational durability. Buyers should independently verify the supplier's API license number and current audit status through the American Petroleum Institute's official licensee directory, as API SPEC 5DP compliance requires active licensure. The company address places it in Changsha, a city with established steel processing and heavy equipment manufacturing infrastructure, though this does not independently confirm production capability. Prospective buyers are advised to request factory audit reports, material test certificates for specific heats numbers, and sample joint dimensional inspection reports before committing to volume orders.
