XCMG XE2000 Welded Steel Pipe (318307800): A Solid Skeleton for Mining Equipment Structure

In core mining regions worldwide, such as Indonesia, the Democratic Republic of Congo, and Brazil, the XCMG XE2000 mining excavator, with its 12-cubic-meter super-large bucket capacity and over 93% mobility, has become a core piece of equipment for efficient mining operations. Within the structural system of this “mining giant,” the welded steel pipe with part number 318307800 acts as a “steel skeleton,” undertaking the crucial responsibilities of supporting key structures and protecting pipelines. It is a core component ensuring the stability of the overall machine structure and the safe operation of the system.

Precise Original Factory Fit, Perfectly Matching the Overall Machine Structure Layout

The XCMG XE2000 welded steel pipe (318307800) was specifically developed by the XCMG R&D team for the overall structural design and functional requirements of the XE2000, undergoing finite element analysis and actual machine load-bearing testing verification. Its pipe diameter accuracy is controlled within ±0.5mm, length error is less than 1mm, and bending angle and curvature perfectly match the machine body structural nodes. Precise installation is achieved in the boom and stick stress areas, as well as in the pipe protection areas of the chassis and slewing platform. This factory-customized compatibility completely eliminates installation gaps or stress concentration problems caused by dimensional deviations, providing a seamless support guarantee for the entire machine structure.

High-strength steel, structural protection under extreme working conditions

Made of low-alloy high-strength structural steel (Q355B) through precision welding, with a tensile strength exceeding 520MPa and a yield strength ≥355MPa, possessing excellent resistance to deformation and fatigue. The steel pipe welds utilize fully automated submerged arc welding technology, resulting in uniform weld reinforcement and sufficient penetration. 100% non-destructive testing ensures the absence of defects such as porosity and cracks, and the weld strength is consistent with the base material. The surface undergoes sandblasting and primer treatment, achieving a rust removal grade of Sa2.5 and a coating adhesion of ≥5MPa. In high-humidity, dusty mining environments, its corrosion resistance is increased by over 40% compared to ordinary steel pipes, and its service life is extended by more than 3 times.

Multiple Functional Integration, Dual Protection and Support

As a key structural support component, this welded steel pipe not only provides rigid support for heavy-duty components such as the boom and slewing mechanism, dispersing concentrated stress during operation, but also provides physical protection for hydraulic lines and electrical wiring harnesses, preventing damage from external collisions and friction. When the XE2000 excavator is fully loaded and excavating hard rock, the steel pipe can withstand instantaneous impact forces of up to 800kN without plastic deformation, ensuring structural stability. Simultaneously, its smooth internal channel design reduces pipe vibration and wear, providing a safe passage for media transmission and indirectly improving the overall machine’s mobility.

For mining companies seeking efficient operations, XCMG XE2000 welded steel pipe (318307800) is not only a high-quality structural component but also a “steel backbone” ensuring the safety of heavy-duty equipment operations. Choosing original equipment manufacturer (OEM) spare parts means choosing structural reliability that perfectly matches the performance of the XE2000 excavator, providing solid structural support for efficient mining operations.
