XCMG XE2000 Excavator Special Steel Pipe Assembly: Part No. 318300806

In the hydraulic and cooling systems of the XCMG XE2000 excavator, the steel pipe assembly is the “core transmission channel” that undertakes the transmission of high-pressure fluid and maintains the stability of system pressure. Its pipe diameter accuracy, pressure resistance and installation compatibility directly determine the fluid transmission efficiency. If the component size is off or the strength is insufficient, it can easily cause serious failures such as pressure loss and pipe bursting. Our 318300806 steel pipe assembly is an original equipment manufacturer (OEM) part specifically customized for the XE2000 model. Manufactured in strict accordance with XCMG’s original fluid piping technical standards and assembly drawings, it undergoes four precision tests, from the outer diameter and wall thickness of the steel pipe to the bending angle and joint dimensions. The outer diameter error is controlled within ±0.08mm, the wall thickness deviation ≤±0.05mm, the bending angle accuracy reaches ±0.5°, and the joint thread accuracy is 6H grade. It can perfectly connect with the XE2000 hydraulic valve group, cylinder interface, and cooler port, allowing for direct assembly without additional cutting or modification. This completely eliminates potential problems such as interface leakage and flow obstruction caused by size mismatch, ensuring efficient and stable transmission of high-pressure fluid.

The dual upgrades in materials and processes give this steel pipe assembly exceptional pressure resistance and damage resistance. The main body of the steel pipe is machined from 20# precision seamless steel tubing, achieving a tensile strength exceeding 410MPa and a yield strength exceeding 245MPa after heat treatment. It can withstand the maximum working pressure of the XE2000 hydraulic system and is resistant to deformation and cracking over long-term use. The surface undergoes galvanizing and passivation treatment, with a zinc layer thickness exceeding 15μm, forming a dense protective layer that effectively resists immersion in mud and water, dust erosion, and hydraulic oil corrosion during mining and construction, preventing the steel pipe from shrinking in inner diameter or leaking due to rust. The assembly joints are made of forged brass, precision machined, and welded to the steel pipe via argon arc welding. The weld joints have a 100% pass rate in flaw detection, with no defects such as porosity or slag inclusions, ensuring overall sealing performance and structural strength. Compared to ordinary welded steel pipe assemblies, its service life is extended by more than 5 times, significantly reducing hydraulic system maintenance caused by pipeline failures and lowering equipment downtime costs.

Whether you’re a maintenance technician on an engineering team needing to replace aging or damaged steel pipe components during hydraulic system maintenance, or a parts distributor looking to stock highly adaptable and reliable fluid transmission spare parts for your customers, the 318300806 steel pipe component is a cost-effective choice.
