Products Description

Through strict quenching and tempering heat treatment, the pipe's mechanical properties are significantly optimized, enabling it to withstand extreme pressure, intense vibration, and repeated impact loads during drilling.

Particularly suitable for shallow drilling operations, it maintains stable performance and long service life even in hard rock, broken formations, or high-abrasion geological environments, making it a cost-effective choice for small-scale projects.

Key Features

High-Quality Material Selection: Crafted from premium 42CrMo alloy steel, processed through high-temperature forging and precision heat treatment. With tensile strength ≥950MPa and hardness HRC 28-32, it boasts excellent impact resistance, toughness, and load-bearing capacity, fully adapting to the harsh conditions of small-to-medium drilling operations.
Precision-Engineered Threads: Adopting CNC precision machining technology to ensure thread accuracy, combined with carburizing and nitriding treatment (HRC 60-65) to enhance wear and corrosion resistance. The optimized thread profile achieves tight engagement, effectively preventing slipping and air/liquid leakage during high-speed rotation.
Lightweight & Rigid Structure: 10-12mm thick wall design balances rigidity and lightweight performance, avoiding deformation under high torque. After sandblasting treatment, an anti-corrosion coating is applied to resist groundwater, soil, and chemical erosion, extending the service life in complex environments.
Universal Compatibility: Compliant with international standards, it perfectly matches mainstream 76mm DTH hammers and bits. The standardized connection design allows for quick assembly and replacement, greatly improving construction efficiency for small-scale projects.
Efficient Energy Transmission: Uniform mechanical properties and reasonable structural design minimize energy loss during drilling, ensuring stable power transmission and high drilling efficiency even in complex shallow strata.

Application Scenarios

Mining: Primarily used for drilling shallow blast holes in small quarries and mines, adapting to hard rock strata and supporting efficient small-scale ore extraction and rock fragmentation operations.
Water/Geothermal Drilling: Suitable for constructing 50-200m shallow and medium-deep water wells for civil and industrial water supply, as well as small-scale geothermal wells to meet local geothermal development needs.
Construction Engineering: Applied in foundation pile drilling, slope reinforcement, and support works for small buildings, rural roads, and community infrastructure projects, ensuring construction stability and safety.
Geological Prospecting: Used for core sampling and stratum detection in small-scale geological surveys, providing accurate data support for local engineering design and geological analysis.

Product Advantages

Extended Service Life: 20-30% longer than ordinary drill pipes, reducing replacement frequency and equipment costs, thereby lowering the overall investment in small-scale construction projects.
High Drilling Efficiency: Stable performance in complex and harsh shallow strata ensures fast drilling speed and high hole straightness, effectively shortening the construction cycle for small projects.
Strong Environmental Adaptability: Resistant to corrosion, deformation, and wear, it can adapt to various harsh geological and working conditions, with a wide range of applications in small-scale operations.
Easy Operation & Maintenance: Standardized structure and connection design facilitate quick installation, disassembly, and replacement, reducing maintenance time and labor costs for on-site operators.
Reliable Quality Assurance: Undergoes strict factory inspections, including material testing, mechanical property testing, and non-destructive testing, with comprehensive after-sales support to ensure safe and stable operation.
