XCMG XE2000 Excavator Steel Pipe Assembly 318307899: The Core of the Piping System

In the piping system of the XCMG XE2000 large excavator, the steel pipe assembly (part number: 318307899) is the “rigid skeleton” for achieving stable transmission of high-pressure media. Like the “arteries” of the hydraulic system, it bears the heavy responsibility of transporting critical media such as hydraulic oil and coolant, providing solid piping support for power transmission and system cooling during high-intensity operation of the XE2000.

Original Factory Precise Fit, Seamless Installation

The steel pipe assembly 318307899 is an original factory piping accessory designed exclusively by XCMG for the XE2000 excavator. Its design is entirely based on the layout parameters and installation requirements of the machine’s piping system. Through 3D modeling and whole-machine piping simulation technology, key parameters such as the length, bending angle, and interface specifications of the steel pipe are precisely determined, ensuring “zero-error” connection with components such as the hydraulic pump, valve group, and radiator. Whether it’s the piping installation during new machine assembly or component replacement during later maintenance, no secondary processing such as cutting or grinding of steel pipes or connecting parts is required, allowing for direct “on-site installation.” This high degree of adaptability not only reduces installation difficulty and shortens the construction cycle but also ensures the sealing and flow efficiency of the piping system, preventing media leakage or pressure loss due to dimensional deviations from the outset.

High-strength structural design, resistant to high-pressure impacts

During heavy-duty operation, the XE2000 excavator’s piping system must withstand media pressures of tens of megapascals and frequent vibration impacts, placing stringent requirements on the structural strength of the steel pipes. The steel pipe assembly 318307899 is precision-machined from high-strength seamless steel pipes with a yield strength exceeding 355MPa. After overall tempering and heat treatment, it possesses excellent compressive strength and fatigue resistance. Its bending parts utilize a cold-bending forming process to avoid material performance degradation caused by heating. The optimized bending radius ensures smooth media flow while enhancing the pipeline’s impact resistance. The steel pipe joints feature precision welding and thread reinforcement, ensuring excellent sealing performance. They can withstand continuous erosion from high-pressure media for extended periods, maintaining structural stability even under severe equipment vibration or sudden load changes, eliminating the risk of leakage.

Precision anti-corrosion process for outstanding durability

XCMG’s quality control for steel pipe components (318307899) covers the entire lifecycle, committed to creating durable pipeline fittings suitable for harsh working conditions. The steel pipe surface undergoes multiple anti-corrosion treatment processes. First, sandblasting removes the oxide layer, followed by high-temperature impregnation and electrostatic spraying for double protection, forming a uniform anti-corrosion coating with a salt spray resistance of over 1000 hours, effectively resisting corrosive media such as mud, oil, and dust in the working environment. For the sealing surfaces at pipe connections, precision grinding and plating are used to improve wear resistance and sealing performance, extending the replacement cycle of seals. Each steel pipe assembly undergoes rigorous testing before leaving the factory, including pressure testing (1.5 times the working pressure without leakage), bending strength testing, and corrosion resistance testing. This ensures stable operation within an extreme temperature range of -40℃ to 120℃, with a service life far exceeding the industry average.

Choosing the XCMG XE2000 excavator steel pipe assembly 318307899 means selecting a highly efficient and durable “transmission channel” for your equipment’s piping system. With its precise original factory compatibility, strong pressure resistance, and outstanding corrosion resistance, it safeguards the XE2000’s piping system in complex operating scenarios such as mining and infrastructure construction, reducing downtime losses due to piping failures, ensuring the continuous and stable operation of the equipment’s power transmission and cooling systems, and facilitating efficient project progress.
