380905381 XCMG GR2605 motor grader metal tube assembly

380905381 XCMG GR2605 motor grader metal tube assembly

The 380905381 metal pipe assembly is a core component of the XCMG GR2605 grader’s original factory-designated hydraulic piping system. It is compatible with the machine’s high-pressure main hydraulic system, undertaking the crucial task of stable delivery and pressure transmission of high-pressure hydraulic oil. It directly affects the accuracy and response speed of key actuators such as the blade lifting main circuit, the articulated steering main circuit, and the hydraulic pump outlet main circuit. In harsh operating environments Characterized by long-term heavy loads, high-frequency vibration, and erosion from dust and mud, such as highway construction, mine stripping, airport runway construction, and large-scale earthwork projects, it can stably withstand instantaneous impact pressures up to 80MPa, without easily experiencing cracks, leaks, or deformation. This effectively reduces the frequency of hydraulic system downtime for maintenance, ensuring continuous equipment operation efficiency.

The metal pipe is made of seamless 304 stainless steel, with a uniform wall thickness (3.5mm), tensile strength ≥520MPa, and excellent compressive strength. It is compatible with one-piece forming process, seamlessly welded to the pipe body (weld strength ≥95% of the base strength). The joint material is 45# steel that has undergone heat treatment, and is sealed with original factory-customized copper gaskets, achieving an IP67 protection level. It perfectly matches the original vehicle interface specifications and can directly replace aged or damaged original vehicle metal pipes.
