318307514 steel pipe assembly XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Steel Pipe Assembly 318307514 – Professional-Grade Load-Bearing Structural Component, Born for Extreme Working Conditions

Core Product Value

The XCMG original XE2000 excavator steel pipe assembly (part number: 318307514) is forged from military-grade alloy steel and optimized through three-dimensional stress analysis. It is specifically developed for continuous high-intensity working environments such as mining and large-scale infrastructure projects. As a key force transmission component of the hydraulic system, this assembly can withstand dynamic loads of up to 200 tons, offering 35% better fatigue resistance than industry standards.

Technical Highlights

🔧 Material Revolution:

• Special chromium-molybdenum alloy steel (grade 42CrMo)

• Ion nitriding surface treatment, hardness reaching HRC58-62

• 100% compliance rate in microstructure testing

⚡ Engineering Verification:

• Passed 8000 pulse pressure tests (ISO 4413 standard)

• Dual certification for -40℃ extreme cold and desert high temperature environments

• Matches the pressure compensation requirements of XCMG intelligent hydraulic systems

🛡️ Protection System:

• Three-layer composite anti-corrosion coating (zinc-nickel + epoxy resin + polyurethane)

• Salt spray corrosion resistance > 2000 hours

• Built-in wear warning indicator design

Typical Fault Solutions

❌ Common Issues with Third-Party Parts:

• Weld cracking (This part uses robotic laser welding)

• Pipe wall deformation (wall thickness reinforced to 12mm)

• Seal failure (Integrates German Bosch Rexroth sealing standards)

Application Scenarios

▌Overload Conditions:

• 24-hour shift operation in iron and copper mines
• Bedrock excavation for Three Gorges-level water conservancy projects
• Construction in polar permafrost zones

▌Benefit Calculation:

• Extends replacement cycle by 300 hours compared to ordinary parts
• Reduces annual maintenance cost per unit by ¥18,000+
• Original manufacturer certification recognized for insurance claims
