Import Drilling Kellys — Buy in Bulk from Supplier in China

Drilling Kellys are precision transmission tools used in oil and gas drilling operations, supplied by Dongying Lake Petroleum Technology Co., Ltd., located in Dongying, China. The product is offered with either square or hexagonal drive configurations to match standard rig couplings. The Kellys are engineered for robust performance under high torque conditions, and the supplier can adapt length and diameter to suit specific rig requirements. These tools form a critical link between the rotary table and the drill string.

Typical material for the Kelly body is high‑strength carbon steel, commonly grade Q235, which provides good tensile strength while remaining cost‑effective. A galvanised coating is usually applied as a surface treatment, delivering corrosion resistance in harsh drilling environments. Standard dimensions include a 76 mm diameter with length options typically ranging from 2 m to 6 m, and drive tolerances are maintained within ±0.2 mm to ensure proper fit. These specifications align with common industry practices for drilling equipment.

The Kellys are purchased by petroleum drilling contractors and service firms that need reliable torque transmission for deep‑well operations. Buyers often place bulk orders and expect the units to be packed in sturdy steel‑framed wooden crates for safe transport. Specific minimum order quantities, lead times and payment terms are not listed in the source data and should be verified directly with the supplier before finalising a contract.

Dongying Lake Petroleum Technology Co., Ltd. operates from Huanghe Road, Dongying, Shandong, China, postal code 257000. The supplier is classified with a harbour trust tier and currently records a 0.00 % response rate, so buyers should confirm communication channels before initiating negotiations.

The company focuses on manufacturing drilling Kellys for petroleum extraction equipment and supplies both domestic and overseas markets. While it lists no specific certifications or client references, it highlights the ability to provide square and hexagonal drive options and to customise length and diameter to match rig specifications.
