OEM 319006278 The XCMG Steel Pipe Assembly 319006278 is a genuine formed and brazed steel tube that carries hydraulic oil between components on XCMG excavators.
Issued under the official part number 319006278, the assembly arrives bent, flanged and fitted so it bolts straight into the machine.
The tube is formed from seamless steel, then bent on CNC machines so the route matches the drawing and clears nearby parts.
Flare or flange ends are machined to the XCMG drawing, so each joint seals against its mating fitting at the designed torque.
Clamps and brackets are welded or brazed in position, so the pipe is supported and does not vibrate against the frame.
Every assembly is checked for bend angle, end form, length and pressure tightness before the batch is released for packing.
Used on main control valves, travel motors, swing motors and boom lines, this pipe assembly keeps oil flowing where the circuit needs it.
The 319006278 assembly is bent to the XCMG drawing, so the route clears the frame, hoses and moving parts on the machine.
Ends are flared or flanged to the OEM form, so each joint seals against its mating fitting at the specified torque.
Seamless steel tube takes full circuit pressure without ballooning or cracking, so the line stays round and clear.
Clamps and brackets sit at the drawing positions, so the pipe is supported and does not chafe against the frame.
A painted or plated finish resists corrosion, so the tube survives wet and dusty working conditions.
Because the assembly carries the OEM number, a technician bolts it in straight from the crate without bending or re-flaring.
Bend angles are held to the drawing, so the tube meets both end fittings without pulling or stressing the joints.
A sound pipe assembly keeps oil flowing with low restriction, which keeps circuit pressure and speed as designed.
Production starts with certified seamless steel tube, checked for grade, diameter, wall thickness and surface condition.
Tubes are bent on CNC machines to the drawing angles, so the radius and route repeat exactly from one assembly to the next.
Ends are flared or flanged and brazed or welded, then cleaned so no scale or burr sits inside the oil path.
Inspectors check bend angle, end form, end thread, overall length and tube roundness on a gauge for this exact part number.
Batch records trace every 319006278 assembly to its tube lot and bending run, so a quality question is settled quickly.
A steel pipe assembly carries oil between valves, motors and cylinders, and the rigid tube resists pressure and vibration.
A cracked, kinked or incorrectly bent pipe restricts flow or leaks, which slows functions and can stop the machine.
The genuine 319006278 follows the original route and end forms, so flow is unobstructed and both joints sit straight.
Correct clamping avoids vibration fatigue, which is a common cause of tube cracking near a brazed end.
A sound pipe protects pumps, valves and cylinders, which keeps service intervals predictable and extends circuit life.
The 319006278 assembly is fitted with a torque wrench, a spanner set and the original clamps during hydraulic service.
Release system pressure, drain the affected line and clean the area so no dirt enters the circuit during the repair.
Check both port threads and seats for damage, then wipe the joint clean and confirm no old seal or thread debris remains.
Offer the pipe up to both fittings without forcing it, and adjust the clamps until the tube sits relaxed in its brackets.
Hold the mating half with a second spanner and tighten both ends to the torque in the service data.
Refill with the specified oil, run the machine slowly and check both joints for weeping after the first pressure cycles.
At service intervals, look for oil film, chafing, loose clamps or rust and renew the assembly before a crack appears.
Every 319006278 assembly is produced in an ISO 9001 and ISO 14001 certified plant with traceability from tube to carton.
Incoming tube is checked for grade and wall thickness, and finished assemblies are gauged for bend angle, ends and length.
Each batch is inspected for brazing or weld defects, dents and tube scoring, since these defects weaken the line.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG routing fixture.
Sample assemblies from each batch undergo proof pressure and salt spray tests to confirm strength and corrosion performance.
Cheap copies often have rough bends or wrong angles, so the tube pulls on its fittings and the joints start to leak.
A pipe with thin walls or poor brazing can crack at pressure or near a clamp, which spills oil and stops the machine.
The genuine 319006278 is formed to the XCMG drawing, so route, bend angle, end form and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM circuits.
Backed by XCMG global quality standards and technical support, this pipe assembly performs reliably in harsh conditions.
Choosing the genuine 319006278 assembly prevents a small leak from turning into a seized pump or a burnt valve.
A cracked pipe can spray hot oil and stop the machine on site, which means lost hours and a bigger repair bill.
A correctly bent tube installs without stress, so both joints stay tight and the circuit does not weep between services.
Reliable lines keep circuit pressure and speed as designed, which lowers the total cost of ownership across a fleet.
Service records from construction and mining fleets show genuine XCMG hydraulic parts cut unplanned downtime.
XCMG produces the 319006278 assembly with efficient bending runs and tight material control that keep production scrap low.
A long service life means fewer replacements, which reduces the steel and energy tied to each assembly.
Stopping oil leaks protects soil and groundwater, helping operators meet rules on environmentally sensitive sites.
The steel in this part complies with RoHS and REACH requirements for safe handling and responsible recycling.
The 319006278 pipe assembly is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each assembly is bagged to protect the ends and boxed in a strong carton that guards against damp and bending in transit.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the bend true and the ends undamaged until fitting, avoiding the problems seen in loose storage.
