XCMG XE2000 Excavator Flange Assembly (803201542): The Core Guarantee of Sealing for Mining Pipeline Connections

In core mining regions worldwide, such as Indonesia, the Democratic Republic of Congo, and Brazil, the XCMG XE2000 mining excavator, with its massive 12-cubic-meter bucket capacity and over 93% mobility, has become a core piece of equipment for efficient mining operations. Within the piping system of this “mining giant,” the flange assembly (part number 803201542) acts as a “precision sealing hub,” undertaking the rigid connection and sealing tasks between high-pressure pipelines. It is a key component ensuring the leak-free transmission of hydraulic oil, coolant, and other media.

Original Factory Precise Fit, Seamless Connection to Piping Systems

The XCMG XE2000 flange assembly (803201542) was specifically designed by the XCMG R&D team for the overall piping layout and pressure parameters of the XE2000 machine, undergoing 3D modeling analysis and actual machine sealing testing verification. Its flange diameter accuracy is controlled within ±0.02mm, bolt hole tolerance is less than 0.1mm, and sealing surface flatness error is ≤0.05mm/m, perfectly matching the interface parameters of key pipelines such as the main pump outlet, control valve group, and cylinder inlet. Whether in static connections of high-pressure hydraulic pipelines or in dynamic sealing scenarios under vibration, it achieves a tight and precise connection, completely eliminating installation gaps or sealing failures caused by dimensional deviations, thus building a “zero-leakage” connection foundation for the pipeline system.

High-strength material, durable core under extreme working conditions

Forged from high-strength alloy structural steel (42CrMo), after tempering heat treatment, the tensile strength reaches up to 1080MPa, and the yield strength is ≥930MPa, possessing excellent pressure resistance and deformation resistance. The flange sealing surface is processed by precision grinding, with a surface roughness Ra≤0.8μm, ensuring a perfect fit with the sealing element. The surface undergoes phosphate treatment and multi-layer anti-corrosion coating protection, achieving over 500 hours of salt spray resistance. In high-humidity, dusty, and highly corrosive mining environments, its rust resistance is improved by more than 40% compared to ordinary flanges, extending its service life by more than 3 times.

Superior sealing performance ensures efficient media transmission

The flange assembly is equipped with imported high-pressure resistant nitrile rubber gaskets, with a hardness controlled at 75±5 Shore A, a compression rebound rate ≥70%, and can withstand a working pressure of 400MPa. The sealing structure adopts a tongue and groove design, combined with precise bolt preload parameters, which can effectively disperse pipeline pressure and prevent seal failure due to excessive local stress. When the XE2000 excavator is operating at full load, it ensures that hydraulic oil and other media pass through the connection point with a transmission efficiency of over 99.5%, providing continuous power support for the powerful digging operation of the 12 cubic meter bucket, avoiding power loss, environmental pollution, and equipment wear caused by leakage. For mining companies seeking efficient operations, the XCMG XE2000 flange assembly (803201542) is not only a high-quality connection component but also a crucial “core barrier” ensuring the sealing and safety of the pipeline system. Choosing original equipment manufacturer (OEM) parts means choosing reliability that perfectly matches the performance of the XE2000 excavator, providing a solid pipeline connection guarantee for efficient mining operations.
