Dongying Lake Petroleum Technology Co., Ltd, based in Dongying, China, supplies DTH Rock Wireline Drill steel Rods designed for down‑hole drilling in oil‑field operations. The rods are offered in metric diameters from 42 mm to 90 mm and conform to the DCDMA parallel‑thread standard, matching sizes such as AW‑HW, AWY‑NWY, AWJ, BWJ and S75. They are manufactured from seamless steel tube of grade XJY850/30CrMnSiA, cold drawn and subsequently heat treated. This construction meets global specifications for strength and wear resistance.
The XJY850 alloy provides a typical tensile strength of around 850 MPa and a hardness of 30 - 38 HRC after heat treatment, giving the rods superior toughness in demanding rock formations. Dimensional tolerance is usually ±0.2 mm and surface roughness is finished to Ra 1.6 µm, which aligns with industry practice for drill‑rod assemblies. The cold‑drawn process yields a uniform grain structure that enhances fatigue life, a standard requirement for long‑run drilling strings. These attributes make the rods comparable to other DCDMA‑compliant products while retaining the supplier’s quality focus.
The rods are intended for petroleum service companies that need reliable wireline drill strings for rock penetration, especially in wells requiring high pull‑out force and torque transmission. Buyers typically order in bulk lengths to match their drilling programme and arrange shipment under FCA or EXW terms as indicated by the supplier. Because the listing does not specify MOQ, lead time or payment conditions, importers should confirm those details directly with Dongying Lake Petroleum Technology before finalising the contract.

Importers should verify that the supplied rods conform to the DCDMA parallel‑thread standard and that the material grade XJY850/30CrMnSiA is accompanied by a material test report. Confirm the exact diameter and tolerance required for the intended drilling string, and request a sample or certification of heat‑treatment if the application demands higher toughness.
Shipping is typically arranged under FCA or EXW incoterms, so the buyer must decide on the forwarder and negotiate freight from the port nearest Dongying. Lead‑time and payment terms are not disclosed in the listing; these should be clarified with the supplier, including any requirement for advance payment or letters of credit.
Before acceptance, arrange third‑party inspection to verify dimensional tolerance, hardness, and tensile strength against the supplied test reports. Ensure that the inspection covers weld‑free integrity and that the rods are free from surface defects. Request the full set of certificates, including heat‑treatment records and any applicable international standards compliance.
