OEM 319007781 The XCMG Steel Pipe Assembly 319007781 is a genuine OEM steel pipe assembly built to carry hydraulic oil on XCMG hydraulic excavators.
Identified by part number 319007781, this factory-made pipe assembly gives technicians a rigid, sealed and correctly routed line for hydraulic service work.
The tube is formed from cold-drawn seamless steel, bent to the exact OEM path, then protected with an anti-corrosion coating inside and out.
Exact outer diameter, wall thickness, bend radius and length allow direct replacement without cutting, welding or adding adapters on site.
By holding pressure and staying rigid under vibration, this steel pipe assembly protects flow stability and keeps the hydraulic circuit clean.
Each unit is pressure checked and dimensionally verified before packing, so the part you receive matches the XCMG drawing specification exactly.
The 319007781 Steel Pipe Assembly uses seamless cold-drawn steel tube that holds its shape and bore under steady hydraulic pressure.
Mandrel bending follows the OEM route precisely, so the pipe clears frames, booms and nearby components without contact or rubbing.
A multi-layer anti-corrosion coating protects the outer surface from moisture, mud and salt, which are common on excavation sites.
Factory-formed end connections seat correctly with original seals and fittings, so the joint seals on the first attempt.
Rigid steel construction resists vibration fatigue far better than flexible hose in high-pressure, high-cycle hydraulic runs.
Exact dimensions mean no field fabrication, no welding and no adapter stacks, which shortens repair time on every machine.
Production starts with certified seamless steel tube checked for wall thickness, ovality, hardness and surface defects before forming.
Each pipe is bent on a CNC mandrel bender that reproduces the XCMG drawing angles and radii within tight tolerance limits.
After bending, ends are formed, deburred and cleaned so no chips or scale can enter the hydraulic circuit during installation.
Inspectors verify bend angle, center distance, length and end geometry against a checking fixture built for this part number.
Batch records trace every 319007781 pipe back to its steel heat number and bending program, so quality questions are answered fast.
The steel pipe assembly carries pressurized hydraulic oil between fixed components where a flexible hose would flex, chafe or balloon.
A cracked or corroded pipe leaks oil, drops circuit pressure and slows boom, arm and bucket response during work cycles.
The genuine 319007781 keeps the line sealed and rigid, so flow stays steady and contamination cannot enter the system.
Correct routing away from hot surfaces and moving parts prevents rubbing damage, which is a leading cause of pipe failure.
Stable hydraulic pressure protects pumps, valves and cylinders, which keeps cycle times and machine uptime predictable.
The 319007781 steel pipe assembly installs with standard hand tools and a torque wrench during scheduled hydraulic service.
Relieve hydraulic pressure fully, shut down the engine and place a drain pan under the connection points before starting work.
Loosen the fittings, remove the old pipe, then clean both ports and inspect threads, seals and mounting clamps for damage.
Position the new pipe along the OEM route, align the ends by hand first, and never force the tube to close a gap.
Tighten fittings to the specified torque, refit the clamps and check that the pipe cannot touch any other component.
Start the engine, cycle the functions slowly, and inspect both joints and the full tube length for weeping or movement.
During routine maintenance, check clamps for looseness and look for rust spots, dents or chafing marks on the coating.
Every 319007781 pipe is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel heat to packed carton.
Incoming tube is tested for wall thickness and material grade, and finished pipes are measured for bore, length and bend angle.
During production, bending force, mandrel condition and coating thickness are monitored so each unit keeps its molded shape.
Post-production checks include visual inspection, dimensional verification and a trial fit on the XCMG hydraulic line fixture.
Sample pipes from each batch undergo pressure, salt spray and vibration tests to confirm long-term performance in the field.
Low-cost aftermarket pipes often use thin-wall tubing that deforms under pressure and corrodes quickly in wet conditions.
A pipe with the wrong bend or length can stress the fitting threads, which leads to seepage and repeated rework.
The genuine 319007781 is formed to the XCMG drawing, so bore, wall, bend path and end geometry match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this steel pipe assembly performs reliably in harsh job sites.
Choosing the genuine 319007781 pipe prevents a small hydraulic weep from turning into an expensive pump or valve repair.
A failed pressure line can drain a reservoir quickly, which starves the pump and damages internal components within minutes.
Proper steel wall thickness and correct coating keep the pipe functional across a long service life, reducing replacement frequency.
Reliable hydraulic delivery also extends pump, seal and oil life, lowering the total cost of ownership for fleet operators.
Service records from construction and mining fleets show genuine XCMG hydraulic parts cut unplanned downtime.
XCMG applies sustainable manufacturing to the 319007781 pipe through efficient bending programs and reduced material waste.
The long service life of the pipe reduces material consumption and lowers the environmental footprint of replacement parts.
Preventing hydraulic leaks protects soil and groundwater and supports compliance on environmentally sensitive sites.
Steel and coating materials in this component comply with RoHS and REACH rules for safe handling and responsible recycling.
The 319007781 steel pipe assembly is held in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Each pipe is capped at both ends and packed in a sturdy carton that protects it from bending, dust and moisture in transit.
For fleet-wide orders, XCMG provides volume pricing and consolidated freight options that simplify planning and reduce cost.
Real-time stock visibility and dedicated supply chain support help fill urgent requests quickly, shortening downtime on projects.
Robust packaging preserves factory condition until installation, preventing the deformation and thread damage common in stored pipes.
The XCMG Steel Pipe Assembly 319007781 is a vital connection component for XCMG excavators, linking fixed hydraulic circuit points.
Its seamless steel tube, anti-corrosion coating and precise bend shape deliver dependable flow in hot, wet and dusty environments.
By preventing leaks and rubbing damage, this steel pipe assembly reduces downtime, lowers maintenance costs and extends service life.
