Diamond Core Drilling Wireline Drill Rods Steel
These wireline drill rods are manufactured from seamless XJY850/30CrMnSiA steel tubing, cold drawn to precise dimensions for use in diamond core drilling operations. Available in DCDMA standard sizes from AW-HW to NWY, with metric diameters ranging from 42mm to 90mm, the rods feature tapered threaded connections designed for compatibility with industry-standard tooling. Each rod is machined to exacting tolerances to ensure smooth torque transmission and minimal vibration during deep core recovery.
The material composition meets international standards for high-strength drill rod applications, with heat treatment enhancing toughness and wear resistance in abrasive formations. The cold-drawn process ensures consistent wall thickness and surface finish, critical for maintaining seal integrity in wireline systems. Typical industry standards for such rods include a minimum tensile strength of 900 MPa and hardness in the range of 28-34 HRC, though exact values are confirmed by batch testing at the manufacturer.
These rods are primarily used by geological survey teams, mining exploration contractors, and geotechnical drilling firms operating in hard rock environments. They are compatible with standard wireline core barrels and are shipped in protective steel crates with individual rod labeling. Trade terms are typically FOB Qingdao, with bulk orders accepted. Minimum order quantities and lead times must be confirmed directly with the supplier.

Sourcing Diamond Core Drilling Wireline Drill Rods Steel from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before placing an order, verify the material specification sheet for XJY850/30CrMnSiA, confirm the thread profile matches your core barrel system, and request test reports for tensile strength, hardness, and dimensional tolerances. Do not rely on marketing claims like 'highest quality' - demand documented proof. Ensure the supplier can provide batch-specific traceability, as this is essential for compliance in mineral exploration projects.
Logistics are typically FOB Qingdao Port, with lead times ranging from 4 to 8 weeks depending on order volume. Incoterms should be confirmed in writing, and payment terms often require a 30% deposit with balance against shipping documents. Packaging is in steel crates, but buyers should specify if they require export-grade corrosion protection or custom labeling for customs clearance.
Quality verification should include visual inspection for thread damage, measurement of outer diameter and wall thickness with calipers, and hardness spot checks using a portable Rockwell tester. Request a copy of the supplier’s internal inspection checklist and ask for photos of packaging before shipment. Retain samples from each batch for future reference in case of field failure.
