XCMG XE2000 Special Steel Pipe Assembly 318307971 – The Robust Artery of Heavy-Duty Hydraulic Systems

When thousand-ton excavators are pushed to their limits, the reliability of every hydraulic line directly determines the overall operating efficiency of the machine. The original steel pipe assembly (part number: 318307971) specially developed for the XCMG XE2000 ultra-large hydraulic excavator, with its superior structural strength and transmission stability, has become an indispensable “rigid transmission expert” in the equipment’s high-pressure hydraulic system, providing reliable power guarantee for heavy-duty operations.

This product is manufactured using special alloy steel through a precision cold-bending process. The inner wall undergoes a special polishing treatment to achieve a mirror finish, and the surface employs a triple anti-corrosion coating technology, resulting in extremely high pressure resistance and impact resistance. Strictly adhering to XCMG’s original technical standards, the pipe diameter accuracy is controlled within ±0.05mm to ensure seamless connection with hydraulic components. The optimized pipeline design significantly reduces hydraulic resistance, enabling the components to maintain stable oil transmission even under ultra-high pressure conditions of 400Bar, effectively suppressing hydraulic pulsations and system vibration.

Suitable for critical transmission components such as the main pump output circuit and high-pressure pipelines of actuators in XE2000 excavators, this steel pipe assembly can withstand a temperature range of -40℃ to 150℃, exhibits excellent fatigue resistance, and maintains structural integrity even under long-term high-pressure operating environments. Its durability, tested for 300,000 pulse cycles, ensures reliable transmission throughout the entire equipment lifespan, completely eliminating the risk of leakage.

Choosing the original manufacturer’s part number 318307971 steel pipe assembly is not only about meticulous equipment maintenance, but also about ensuring high uptime. Let robust pipelines transmit thousands of tons of power, demonstrating professional value through reliable transmission!

Note: This product is suitable for XCMG XE2000 series excavators. Please confirm the equipment model and part number match your requirements before purchasing.
