The 803111145 Flange is a precision‑engineered hydraulic connection component that provides a secure, leak‑proof interface between hydraulic hoses, tubes, and equipment ports on XCMG articulated dump trucks.
This genuine OEM flange is manufactured from high‑strength forged steel and coated with a corrosion‑resistant zinc‑nickel finish, ensuring exceptional durability in the harshest mining and construction environments.
Designed to withstand extreme pressures up to 35 MPa and temperatures ranging from -40°C to +120°C, the 803111145 flange delivers reliable, leak‑free performance in critical hydraulic circuits.
Its standard ISO 6162 split‑flange design and precise bolt pattern ensure easy installation and compatibility with existing hydraulic lines, making it the ideal replacement for worn or damaged flanges.
A compromised flange can lead to catastrophic fluid leaks and system failure. The 803111145 flange eliminates these risks with rugged, long‑lasting construction.
In XCMG articulated dump trucks, hydraulic flanges are the primary connection points that join hoses and tubes to pumps, valves, cylinders, and other components.
The 803111145 flange is typically used in high‑pressure circuits where a leak‑free seal is essential for maintaining system pressure and preventing fluid loss.
A properly torqued flange with a compatible O‑ring provides a robust seal that withstands vibration, thermal cycling, and pressure surges.
Without a reliable flange connection, hydraulic oil can escape, leading to pressure drops, component wear, and environmental contamination.
The 803111145 flange is engineered to maintain its sealing integrity over thousands of operating hours, contributing to the overall reliability of the machine.
The 803111145 flange is designed with a focus on strength, precision, and corrosion resistance. Its forged steel construction provides superior mechanical properties compared to cast alternatives.
The flange face is precision‑machined to a smooth finish that ensures proper sealing with the O‑ring, while the bolt holes are accurately positioned to ensure even clamping force distribution.
The zinc‑nickel coating offers excellent protection against corrosion, withstanding over 200 hours of salt‑spray testing per ISO 9227.
The flange is designed to accommodate standard O‑ring seals (NBR or FKM), allowing for compatibility with a wide range of hydraulic fluids and temperatures.
Its split‑flange design allows for easy installation and removal without disturbing the entire hydraulic line, reducing maintenance time.
The 803111145 flange is treated with a zinc‑nickel electroplating process that provides superior corrosion resistance compared to standard zinc plating.
This coating offers excellent protection against road salt, moisture, and chemical exposure, ensuring the flange maintains its structural integrity over time.
The coating thickness is carefully controlled to maintain the dimensional tolerances of the bolt holes and sealing face.
A clear passivation layer is applied after plating to further enhance corrosion resistance and provide a uniform appearance.
This advanced coating technology ensures that the 803111145 flange delivers reliable performance in the harshest mining and construction environments.
The 803111145 flange is used extensively in XCMG articulated dump trucks and other heavy equipment in surface mining, underground mining, and large‑scale construction.
It is commonly installed at hydraulic pump outlets, valve bank connections, cylinder ports, and hose junction points where a robust, leak‑free connection is required.
The flange’s ability to handle high pressures and harsh conditions makes it ideal for steering, braking, and suspension hydraulic circuits.
Its corrosion‑resistant finish ensures reliable operation in dusty, wet, and high‑humidity environments common in mining and quarrying operations.
The 803111145 flange is also compatible with other XCMG equipment, including wheel loaders and excavators that use ISO 6162 split‑flange connections.
Every 803111145 flange is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Incoming raw materials are tested for chemical composition and mechanical properties to ensure they meet the required specifications.
During machining, each flange is inspected for dimensional accuracy, thread quality, and surface finish using precision measuring equipment.
After coating, the flange is subjected to salt‑spray testing to verify corrosion resistance, and a sample from each batch is pressure‑tested to 1.5 times the working pressure.
This comprehensive quality assurance programme guarantees that every 803111145 flange meets XCMG’s exacting standards for safety and reliability.
The 803111145 flange is designed as a direct replacement for the original flange on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its bolt hole pattern (4 × M12, 70 mm PCD) and overall dimensions match the factory specifications, ensuring a seamless installation.
The flange is supplied without the O‑ring seal, allowing the installer to choose the appropriate seal material (NBR, FKM, etc.) for their specific fluid and temperature requirements.
For cross‑brand applications, verify that the flange size, bolt pattern, and pressure rating are compatible with your specific hydraulic system.
Always consult the parts manual to confirm the correct flange for your machine.
Proper installation of the 803111145 flange is essential to ensure a leak‑free connection. Begin by depressurizing the hydraulic system and cleaning the mating surfaces of dirt, old sealant, or debris.
Inspect the O‑ring groove and replace the O‑ring with a new seal of the correct material and size. Apply a thin film of hydraulic oil to the O‑ring to aid seating.
Position the flange halves over the hose or tube end, align the bolt holes, and insert the bolts. Tighten the bolts evenly in a cross‑pattern to the recommended torque (typically 40‑50 N·m for M12 bolts).
Re‑pressurize the system and check for leaks around the flange. If leaks are present, re‑tighten the bolts slightly, but avoid over‑torquing, which can damage the flange or O‑ring.
During routine maintenance, inspect the flange for signs of corrosion, damaged threads, or leakage. Replace the flange immediately if any damage is found.
Regularly check the torque on the flange bolts as part of the preventive maintenance schedule, especially on equipment subjected to high vibration.
The 803111145 flange complies with ISO 6162 and SAE J518 standards for split‑flange hydraulic connections, ensuring compatibility with industry‑standard components.
It meets the pressure and temperature requirements for heavy‑duty off‑highway equipment as specified by ISO 9001.
The materials used are free from restricted substances and comply with RoHS and REACH regulations.
