Drilling Kellys
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.

Sourcing Drilling Kellys from Dongying Lake Petroleum Technology Co., Ltd. - China Import Guide
Before confirming a purchase, verify the exact steel grade, drive type, length, diameter and surface coating against your rig’s technical requirements. Request detailed engineering drawings and confirm that the drive tolerance aligns with your coupling specifications. It is advisable to obtain a sample or mock‑up for fit testing prior to large‑scale procurement.
Clarify logistics by agreeing on the preferred Incoterm, typical lead time and the designated loading port in China. Because the supplier’s response rate is currently zero, establish a written agreement covering payment terms such as a letter of credit or advance payment, and confirm whether freight forwarding services are included or need to be arranged separately.
Adopt a quality control process that includes third‑party dimensional inspection and receipt of material test certificates upon shipment. Ask for a pre‑shipment inspection report documenting compliance with diameter, length and surface‑treatment specifications. Ensure that the supplier provides a packing list, certificate of origin and any required export documentation to streamline customs clearance at the destination.
