318307310 steel pipe assembly XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Ultra-High Pressure Steel Pipe Assembly 318307310 – Core of Mining-Grade Hydraulic Transmission

Product Core Value

The XCMG original XE2000 ultra-high pressure steel pipe assembly (part number: 318307310) is precision cold-drawn from 42CrMo special alloy steel, with a burst pressure of 65MPa, specifically designed for extreme mining conditions. It is ISO 10763 certified, with a pulse life exceeding 800,000 cycles, and 350% better fatigue resistance than ordinary steel pipes, making it a core transmission component ensuring stable operation of the hydraulic system.

Six Major Technological Breakthroughs

🛠️ Military-Grade Manufacturing Process

• Uses 42CrMo4 high-strength alloy steel (tensile strength ≥1100MPa)

• Mirror-polished inner wall (roughness Ra≤0.2μm)

• Ultra-deep cryogenic treatment (-196℃ liquid nitrogen quenching)

⚡ Intelligent Buffer System

• Integrated hydraulic pulse damper

• 3D stress-optimized layout

• Vibration transmission reduced by 60% (CNAS certified)

🔍 Ultra-Precision Connection Technology

• 37° flared sealing structure (ISO 8434-1 standard)

• Laser-aligned positioning groove

• Pre-set torque indicator mark

🛡️ All-Around Protection System

• Four-layer composite coating (zinc-nickel + ceramic + polyurethane + rust-preventive oil)

• 3000-hour salt spray corrosion resistance

• Explosion-proof warning color ring design

📊 Digital Operation and Maintenance Management

• Independent blockchain ID for each steel pipe

• AR remote maintenance navigation

• Real-time stress monitoring interface

Extreme Environment Adaptability

• -50℃ low temperature impact energy ≥75J

• High-altitude low air pressure compensation design

• Electromagnetic interference resistance (EMC Class 4)

Performance Comparison Test

Indicators: This product/Ordinary steel pipe
Burning pressure (MPa): 65/32
