OEM 318502141 The XCMG Flange 318502141 is a genuine bolted flange that joins pipe sections and ports on XCMG hydraulic excavators with a tight, serviceable joint.
Issued under the official part number 318502141, the flange gives the technician a correctly sized connector that matches the bolt circle, bore and sealing face it is designed for.
The flange is machined to the XCMG drawing, so the bolt pattern, outside diameter and face finish line up with the mating part without re-drilling.
A flat machined sealing face presses evenly against the gasket, so the joint seals instead of weeping at a high spot.
A protective plating resists oil, water and corrosion, so the flange keeps its face and finish through wash-down and long outdoor duty.
Every unit is checked for bolt circle, bore, face flatness and surface finish before the batch is packed for shipment.
Fitted to hydraulic lines, coolant pipes and pump ports, this flange keeps the joint tight, aligned and easy to take apart for service.
The 318502141 flange is produced to the XCMG drawing, so the bolt circle and bore line up with the mating part on the first attempt.
A flat machined face presses evenly on the gasket, so the joint seals instead of weeping at a high spot or a rough edge.
Correct thickness keeps the flange rigid under bolt torque, so it does not bow and lose gasket pressure between bolts.
The plated finish resists water, dust and wash chemicals, so the flange does not rust or seize to the pipe over time.
Because the part matches the OEM number, a fitter installs it straight from the bag without re-drilling, filing or adding spacers.
Even bolt spacing spreads the clamping load, so the gasket compresses uniformly and the joint stays leak-free.
A sound flange also keeps pipes aligned, which reduces stress on hoses, brackets and the ports they connect to.
Keeping a spare flange on the shelf shortens repair time, so a weeping joint does not turn into a full day of lost work.
Each lot begins with certified steel billet or bar tested for chemistry, hardness and pressure strength before machining.
Flanges are turned, drilled and faced in controlled tooling, so the bore, bolt circle and thickness stay uniform from batch to batch.
Deburring removes sharp edges from the holes and face, so the flange seats flat and does not cut the gasket or hands.
Inspectors measure bolt circle, bore diameter, thickness and face flatness against a gauge made for this exact part number.
Batch records trace every 318502141 flange to its steel lot and production run, so a quality question is settled quickly.
A flange joins two pipe sections or a pipe to a port, so fluid flows between components through a bolted, serviceable joint.
A warped or corroded flange lets the joint weep and lets air enter, which causes pressure loss and unexpected failure.
The genuine 318502141 keeps the joint tight, so pressure holds and the surrounding parts stay clean and dry.
Correct fit avoids both a flange that sits proud and leaks at the gasket and one that binds and cracks the port.
A sound flange protects hoses, pumps and cylinders, which keeps service intervals predictable and extends machine life.
The 318502141 flange is installed with a cleaning cloth, a spanner set and a gasket set during hydraulic or cooling service work.
Release system pressure, drain the affected line and clean the flange faces so no dirt or old gasket sits in the joint.
Check the mating faces and bolt holes for damage, rust or old sealant, since a rough face will stop the flange sealing fully.
Fit a new gasket, align the flange with the mating part and start the bolts by hand so the thread is not cross-threaded.
Tighten the bolts in a cross pattern to the torque in the service data, so the gasket compresses evenly without cracking the flange.
Refill the system, run the machine slowly and check the joint for weeping after the first pressure cycles.
At service intervals, look for fluid film, loose bolts or a rusted face and renew the part before the leak spreads.
Every 318502141 flange is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel to carton.
Incoming steel is tested for chemistry and hardness, and finished flanges are gauged for bolt circle, bore and thickness.
Each batch is screened for cracks, laps and coating defects, since these flaws cause leaks or let the flange crack under pressure.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG pipe fixture.
Sample flanges from each batch undergo pressure, torque and salt spray tests to confirm sealing and corrosion performance.
Cheap copies often use soft steel or rough facing, so the flange bows, weeps at the gasket or cracks at the bolt holes.
A flange with the wrong bolt circle or bore can leak, cross-thread the bolts or fail to align the pipe with the port.
The genuine 318502141 is made to the XCMG drawing, so bolt circle, bore, thickness and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM piping.
Backed by XCMG global quality standards and technical support, this flange performs reliably in harsh conditions.
Choosing the genuine 318502141 flange prevents a small weep from turning into a damaged pump or hydraulic component.
A failed flange lets fluid escape and air enter, which causes pressure loss and shortens component life.
A correctly made flange seals firmly, so it does not need repeated tightening and does not wear out the gasket or bolts.
Reliable flanges also keep pressure contained, which improves machine performance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 318502141 flange with efficient machining runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each flange.
Sealing pipe joints prevents fluid leaks and contamination, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 318502141 flange is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is bagged to protect the sealing face and boxed in a strong carton that guards against dust, damp and crushing.
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 flange flat and the sealing face undamaged until fitting, avoiding the distortion seen in loose storage.
