318307316 steel pipe assembly XCMG XE2000 excavator spare parts

XCMG XE2000 Steel Pipe Assembly (Part No. 318307316): The Rigid Core of Hydraulic Power Transmission

In the high-pressure hydraulic system of large mining excavators, the steel pipe assembly is the “rigid artery” that carries the long-distance, high-pressure transmission of hydraulic oil. XCMG’s specially developed steel pipe assembly (part no. 318307316) for the XE2000 excavator, made of high-strength alloy material and precision manufacturing process, becomes the core guarantee for efficient transmission of hydraulic power in heavy-duty operations, providing a stable and reliable pipeline transmission solution for engineering teams worldwide.

High-strength alloy substrate, forging a foundation for pressure-resistant transmission

The XCMG XE2000 steel pipe assembly (part no. 318307316) is manufactured using high-quality low-alloy high-strength seamless steel pipe. Authoritative testing shows that its tensile strength reaches 850MPa, and its yield strength exceeds 720MPa, representing a 40% increase in strength compared to conventional steel pipes in the industry. Through XCMG’s proprietary “precision cold drawing + overall quenching and tempering” process, the inner wall smoothness of the steel pipe reaches Ra1.2μm, and the wall thickness uniformity is controlled within ±0.2mm, eliminating the risk of local deformation or breakage under high-pressure conditions.

Each steel pipe undergoes four rigorous tests: 45MPa ultra-high pressure water pressure test (30 minutes pressure holding without leakage), ultrasonic flaw detection (no internal defects), bending fatigue test (150,000 cycles without cracks), and salt spray test (1800 hours without rust). Actual test data shows that during 3500 hours of continuous heavy-load operation, the pressure loss rate of this component is less than 1.5%, and its service life is extended by 150% compared to ordinary steel pipe components.

Optimized flow channel design improves transmission efficiency

To address the ultra-high flow hydraulic demands of the XE2000 excavator, the steel pipe component adopts a fluid dynamics-optimized flow channel structure. 3D simulation technology was used to determine the optimal pipe diameter and pipeline routing, reducing hydraulic oil flow resistance by 28%. The steel pipe ends are precision forged and CNC ground, with a flatness error of ≤0.02mm at the mating surface, ensuring a micron-level fit with the flange assembly and reducing pressure loss due to connection gaps.

The bending section of the assembly uses CNC cold bending forming, with a bending radius accuracy controlled within ±0.5mm and a wall thickness reduction rate of ≤5% at the bend, far below the industry standard of 10%. Actual testing shows that the hydraulic oil transmission efficiency of this steel pipe assembly is 18% higher than traditional pipelines, increasing the excavator’s power response speed by 12% during heavy-duty operations and effectively reducing system energy loss.

Adaptable to all operating conditions, ensuring system stability

This steel pipe assembly is specifically designed for the extreme operating environment of the XE2000 excavator, maintaining stable performance within a temperature range of -45℃ to 120℃. Its surface employs a dual anti-corrosion process of “zinc-nickel alloy plating + ceramic sealing,” with a coating thickness exceeding 90μm. This provides four times the corrosion resistance of ordinary galvanized steel pipes, enabling long-term stable operation in high-humidity coastal mining areas, dusty mines, and high-salt environments.

Actual engineering application data shows that XE2000 excavators equipped with this component experience an 80% reduction in hydraulic pipeline failure rate and a 92% reduction in downtime due to pipeline issues. In mining operations at altitudes of 5500 meters, the steel pipe assembly exhibits no cavitation; in continuous vibration crushing operations, pipeline joints show no loosening or leakage; and in high-temperature desert environments, pipeline thermal deformation is controlled within 0.1mm/m, ensuring consistently efficient operation of the hydraulic system.

Original Factory Precise Fit, Enhanced System Efficiency

As a core original hydraulic component from XCMG, the 318307316 steel pipe assembly achieves 100% precise matching with the hydraulic system of the XE2000 excavator. The pipe routing and layout perfectly match the overall machine structure design. Parameters such as component length and bending angle have been optimized through finite element analysis, achieving optimal pipe layout within limited equipment space, reducing pipe interference and energy loss.

The installation process employs a “modular pre-assembly + locating pin fixing” design, combined with original factory-specific clamps, achieving an installation accuracy of 0.05mm, improving efficiency by 65% ​​compared to traditional pipe installation methods. Data shows that using the original factory steel pipe assembly can reduce energy loss in the XE2000 excavator’s hydraulic system by 10%, reduce overall operating fuel consumption by 8%, and extend the service life of hydraulic components by 70%. Choosing XCMG XE2000 steel pipe assemblies (part number 318307316) means selecting hydraulic transmission assurance for your heavy equipment that has been proven under extreme working conditions. This ensures that the high-pressure hydraulic system maintains efficient and stable operation during high-intensity work, creating greater economic benefits and equipment reliability for your project.
