Drill Collar
Dongying Lake Petroleum Technology Co., Ltd offers drill collars designed to improve weight distribution and prevent buckling in demanding drilling programmes. The collars are manufactured to meet API 7 and ISO standards, providing a recognised benchmark for strength and durability. They are fabricated from high‑strength steel, with optional spiral‑groove profiles that enhance mud flow around the tool. The design focuses on precise dimensional control to fit standard drill pipe connections.
In the industry, a common outer diameter for drill collars is 76 mm with an inner diameter of 68 mm, and lengths typically range from 300 mm to 1800 mm, which matches the sizes compatible with most rotary‑cone rigs. Standard hardness for this class is 45‑50 HRC and tensile strength is usually above 1200 MPa, values that ensure reliable performance under high‑pressure conditions. The collars are threaded to API 8‑1 specifications and are rated for pressures up to 200 MPa, allowing use in both onshore and offshore wells.
These products are targeted at oil‑field operators, geothermal developers and mining companies that require stable drill string weight at the bit. Dongying Lake ships the collars in reinforced wooden crates or steel pallets and accepts L/C or T/T payment, but exact MOQ, lead time and packaging dimensions should be confirmed with the supplier. Importers are advised to request the mill test report and any applicable ISO or API certificates before finalising the purchase.

Sourcing Drill Collar from Dongying Lake Petroleum Technology co.,ltd - China Import Guide
Before ordering from Dongying Lake Petroleum Technology Co., Ltd, importers should obtain the most recent mill test report and verify that the drill collar complies with API 7 and the applicable ISO standard. Confirm that the outer and inner diameters, as well as the length, fall within the typical tolerances stated for the product. Any deviations from the typical values must be recorded and approved in writing before shipment.
The supplier indicates that units are packed in reinforced wooden crates or steel pallets and can be shipped under FOB or CIF incoterms. Because the response rate shown is 0 percent, buyers should ask the sales team to confirm the anticipated lead time and any minimum order requirements. Accepted payment methods include L/C and T/T, but the exact terms should be negotiated prior to contract signing.
Arrange a third‑party inspection at the factory or at the loading port to validate hardness, tensile strength and thread dimensions against the supplied certificates. If the application involves high pressure, ensure the inspector can perform a hydrostatic test to verify the 200 MPa rating. Keep all inspection reports, certificates and packing documentation as part of the import file to satisfy customs and quality‑assurance procedures.
