Drill Collars
Dongying Lake Petroleum Technology Co., Ltd supplies drill collars manufactured in China. The collars provide a hardness between 285 and 341 BHN, meeting the durability requirements of demanding drilling operations. They also achieve a Charpy impact value of 40 ft·lb, indicating resistance to sudden loads. Sizes and weights can be customised to match project specifications.
The products are forged from alloy steel, a material commonly used for drill collars because of its tensile strength and wear resistance. In the oilfield sector, typical drill collars conform to grades such as P110 or P205, with diameters ranging from 4 to 12 inches and lengths from 2 to 8 feet; the listed items can be produced within these ranges. This aligns with standard practice for drilling rigs that require stable weight‑on‑bit and column stiffness.
Drill collars are employed in oil and gas wells, mining boreholes and large‑scale construction drilling, where reliable weight transfer is critical. Importers usually request flexible minimum order quantities and secure packaging, and the supplier notes that FOB and CIF shipments are available. Prospective buyers should confirm exact lead times, payment conditions and any required certifications directly with Dongying Lake Petroleum Technology Co., Ltd.

Sourcing Drill Collars from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before placing an order, verify that the drill collars meet the required hardness and impact specifications by requesting the latest mill test reports. Confirm the material grade and any ISO 9001 certification to ensure conformity with your project standards. Because the supplier’s response rate is currently zero, establish a reliable point of contact through alternative channels such as a direct email or phone call to avoid communication gaps.
Discuss the preferred Incoterm - FOB or CIF - and obtain a detailed shipping quotation that includes freight, insurance and handling charges. Ask the supplier for an estimated lead time based on the customised size and weight you need, as this can vary with production scheduling. Clarify payment methods, such as irrevocable Letter of Credit or Telegraphic Transfer, and confirm any advance payment requirements before finalising the contract.
Arrange an independent third‑party inspection at the factory or during loading to verify dimensions, hardness and impact values against the agreed data sheet. Request the full set of documentation, including material test certificates, packing list and bill of lading, to facilitate customs clearance. Maintaining these checks helps guarantee that the delivered drill collars perform reliably in the field.
