Dth drilling rig spare parts from Shandong Yikuang Drilling Technology Co., Ltd. consist primarily of friction-welded drill pipes made from low carbon steel, designed for use in rock drilling applications including mining, geothermal, and water well projects. The pipes are manufactured to withstand cyclic compression and tensile stress, with weld joints engineered to maintain structural integrity under high-impact conditions. Dimensions and thread profiles follow industry-standard DTH configurations, compatible with common hammer systems such as Sandvik and Atlas Copco models.
The base material is typically SAE 4140 or equivalent low alloy steel, offering a balance of toughness and wear resistance. The friction welding process ensures a seamless bond between the pipe body and adapter, eliminating threaded connections that can loosen under vibration. Surface finish is ground to reduce friction during operation, and internal bore tolerances are held within ±0.1 mm to ensure consistent airflow and debris expulsion. These are not coated or plated; performance relies on material composition and heat treatment, not surface layers.
These components are purchased by drilling contractors operating in hard rock environments, particularly in China, Southeast Asia, and Africa, where deep borehole drilling is common. Buyers typically order in batches of 50 to 200 pieces per shipment, packaged in steel crates with anti-rust paper. Lead times vary by order volume and are confirmed directly with the supplier. Incoterms offered are typically FOB Qingdao or CIF destination port, with payment via T/T or L/C.
| Material | Low carbon steel, typically SAE 4140 or equivalent |
| Welding method | Friction welding, no threaded joints |
| Pipe outer diameter range | 76 mm to 152 mm, standard for medium to large DTH hammers |
| Thread profile | ISO 11078 compliant, compatible with common DTH hammer interfaces |
| Tensile strength | Typical range 900 MPa to 1100 MPa for this grade of steel |
| Hardness | Typical HRC 28 to 34 after heat treatment |
| Bore tolerance | ±0.1 mm internal diameter, standard for efficient air flow |
| Length tolerance | ±2 mm per pipe segment, typical for industrial drilling applications |
| Packaging | Steel crates with anti-rust paper, 20 to 50 pieces per crate |
| Surface finish | Ground internal bore, no plating or coating |
Shandong Yikuang Drilling Technology Co., Ltd. operates from Linqing, Shandong Province, with a focus on manufacturing DTH drilling components. The company is registered as a harbor-tier supplier, indicating verified business registration and production capacity. There is no public information on years in operation, employee count, or export history. The listing confirms only that the supplier produces friction-welded drill pipes using low carbon steel, with no mention of certifications, R&D teams, or third-party testing.
The supplier does not claim ISO certification, laboratory testing, or client references. Response rate and average response time are not available, suggesting limited customer service infrastructure. Buyers should treat this as a direct manufacturer of core components without additional value-added services such as custom design, technical support, or warranty programs. All claims are limited to the description provided in the listing.

Before placing an order, verify the material grade and heat treatment process with the supplier. Request a material test report showing tensile strength, hardness, and chemical composition for the specific batch. Confirm that the thread profile matches your hammer model using ISO 11078 as reference. Do not accept products without documented weld inspection, as internal defects are invisible to the naked eye and can cause catastrophic failure during operation.
Lead time is typically 20 to 45 days depending on order volume, and must be confirmed in writing. Incoterms are usually FOB Qingdao, but CIF or CFR may be negotiable. Payment terms are commonly 30% advance and 70% against copy of B/L. Packaging is in steel crates with anti-rust paper, but buyers should specify if they require wooden pallets or fumigation certificates for destination countries with strict phytosanitary rules.
For quality assurance, insist on ultrasonic testing reports for all friction-welded joints and dimensional inspection records for bore and thread tolerances. Request samples for field testing under simulated conditions before large orders. Document any deviations in surface finish or thread fit upon receipt. Retain shipping samples for 90 days in case of warranty claims. Avoid accepting products without batch-specific documentation, as traceability is critical in high-risk drilling environments.
