The DTH Drill Pipe supplied by Dongying Lake Petroleum Technology Co., Ltd. is an API 5D‑compliant conduit used for well drilling and mining applications. The listing specifies outer diameters of 2 7/8", 3 1/2", 4", 4 1/2", 5" and 5‑1/2", with steel grades e75, x95, g105 and s135 available. End finishes are offered as external upset (EU) or internal‑and‑external upset (IEU), and the product can be supplied with or without hard‑banding such as ARNCO100, ARNCO300 or tungsten carbide inserts.
Typical DTH drill pipes feature a wall thickness ranging from 12 mm to 22 mm and are supplied in standard joint lengths of 9.5 m. The connection type conforms to the API 5D thread standard, enabling compatibility with a broad selection of drilling rigs. Maximum working pressure for these pipes is usually rated up to 200 bar, and the weight per metre is commonly around 45 kg, depending on diameter and wall thickness.
These pipes are purchased by oil‑field service companies, mining contractors and drilling equipment distributors that require reliable pressure containment and dimensional stability. Importers should confirm the exact steel grade, end‑finish type and any hard‑banding requirements before finalising a purchase. As the listing does not disclose pricing, MOQ or lead‑time, those details must be negotiated directly with the supplier.

Prior to ordering, verify the supplier’s business licence, request a copy of the API 5D certification and confirm the exact steel grade and end‑finish type needed for your drilling rig. Ask for dimensional drawings that show wall thickness and thread profile to ensure compatibility with existing equipment. Clarify whether hard‑banding will be applied and obtain a test report for the coating if required.
Shipping from Dongying usually departs from nearby ports such as Tianjin or Qingdao. Confirm the Incoterm you prefer - FOB, CIF or DDP - and obtain an estimated lead time once the technical specifications are finalised. Discuss payment structures, for example a 30 % advance with the balance payable against the Bill of Lading, to align with your company’s financial controls.
Quality assurance for drill pipe includes hydrostatic pressure testing, tensile strength verification and visual inspection for surface defects. Request a test certificate that records the results of these examinations and consider arranging a third‑party inspection at the factory before shipment. Ensure the documentation includes the API 5D compliance statement and any hard‑banding test data.
