The API Heavy Weight Drill Pipe and Drill Collar from Dongying Lake Petroleum Technology Co., Ltd. are engineered for stability and control in drilling operations. The drill pipe complies with API standards, while the drill collar adds weight to the bottom hole assembly, improving verticality and penetration rates. Both components are constructed from high-strength steel, with the drill collar typically featuring thicker walls and larger outer diameters to provide the necessary weight for directional drilling.
Standard drill collar dimensions often range from 3" to 11" in outer diameter, with lengths typically between 9 to 10 meters, though custom lengths are available. The drill pipe is available in API-compliant grades such as E75, X95, G105, and S135, with connection types including NC26 to NC55 and 6-5/8FH. Typical industry specifications for drill collars include a density of approximately 7.85 g/cm³ and a tensile strength exceeding 90,000 psi for standard grades.
These products are widely used in oil and gas exploration, construction, and mining, where precision and durability are critical. The supplier offers third-party inspection options and flexible MOQ terms, though specific pricing, lead times, and packaging details must be confirmed directly. Buyers should verify compatibility with existing drill strings and rig capabilities before ordering.

Before placing an order, verify the compatibility of the drill pipe and collar dimensions, material grades, and connection types with your existing drill string and rig specifications. Request API compliance certificates and mill test reports to confirm the products meet industry standards. For drill collars, check the weight and length to ensure they provide the necessary bottom hole assembly stability for your well depth and trajectory.
Discuss logistics details such as the port of loading (likely Qingdao or Tianjin for Shandong-based suppliers), incoterms (FOB or CIF are typical for bulk oilfield equipment), and lead time, which can vary based on order size and customization. Confirm payment terms, as these are often negotiable for large or recurring orders. Ensure the supplier can accommodate your preferred shipping method, whether bulk vessel or containerized, and verify handling requirements for heavy equipment.
For quality assurance, insist on third-party inspections at the manufacturer’s facility or prior to shipment. Inspect drill pipes for wall thickness consistency, connection integrity, and hard banding application. For drill collars, verify outer diameter, wall thickness, and hardness. Request documentation such as API monograms, material traceability records, and inspection certificates. For critical applications, consider additional non-destructive testing (NDT) to detect internal or surface defects that could compromise performance.
