Dongying Lake Petroleum Technology Co., Ltd manufactures DCDMA PQ BQ Wireline Drill Rods, heat‑treated geological steel rods for wireline drilling operations. The rods are supplied in DCDMA size series AW, BW, NW and HW, with tapered threaded tool joints AWY, BWY and NWY. Wireline size options include metric diameters 42 mm, 50 mm, 60 mm, 70 mm and 90 mm. All products undergo whole‑length heat treatment and screw‑thread heat treatment.
The material grades offered are 30CrMnSiA (A grade) and 45MnMoB (A grade), as well as XJY850 (B grade) and BG850 (B grade), providing yield strengths typically above 800 MPa. Pin ends receive a hard‑chromed coating, a finish that commonly achieves a surface hardness of around 65 HRc. Standard industry tolerances for diameter are ±0.2 mm, and the rods are machined on NC lathes with former cutters to maintain geometric accuracy. These specifications align with the requirements of demanding oil‑field drilling where wear resistance and tensile strength are critical.
The drill rods are sold wholesale to drilling contractors and service companies that require reliable wireline equipment. Packaging is normally in bundled steel crates, with quantities determined during order negotiation; the exact minimum order quantity must be confirmed with the supplier. Buyers should verify the applicable Incoterms, typical payment terms such as T/T or L/C, and any required documentation before shipment. Dongying Lake Petroleum Technology Co., Ltd can provide material test certificates and heat‑treatment records on request.

Before placing an order, confirm the exact material grade, heat‑treatment records and the diameter tolerance required for your wireline system. Request the supplier’s mill test certificate and a dimensional inspection report to ensure the rods meet the specified standards. Verify that the threaded joint type (AWY, BWY or NWY) matches your equipment, and ask whether any surface‑hardening treatments beyond the hard‑chromed pin are available.
Logistics for these drill rods are typically arranged under FOB or CIF terms, but the precise Incoterm should be agreed with Dongying Lake Petroleum Technology Co., Ltd during quotation. Lead times are not disclosed in the public data, so ask the supplier for an estimated production and shipping schedule. Payment methods such as T/T in advance or a documentary letter of credit are common in the industry, and should be confirmed before contract signing.
For quality assurance, request a third‑party inspection at the factory or upon arrival, focusing on heat‑treatment compliance and surface hardness of the pin end. The supplier can provide material test certificates, heat‑treatment logs, and dimensional verification sheets. Maintaining a clear record of these documents will help you meet project specifications and regulatory requirements.
