• Thick steel pipe body with high mechanical strength, resist thermal deformation under long-time high-temperature exhaust impact.
• High-temperature anti-oxidation coating slows down oxidation and rusting of pipe surface, extend service life in high heat and dusty environment.
• Optimized bending design keeps smooth exhaust flow, reduces exhaust backpressure, avoids loss of engine power.
• Flange and pipe integrated welding, reliable weld seam, effectively prevent exhaust gas leakage under vibration.
• Standard dimension and flange hole position, perfectly match original machine interface, simple installation and replacement.
• Reduce risk of high-temperature gas leakage, avoid scalding operators and burning nearby rubber hoses and wiring harnesses.

FAQ 

Q1：Which loader does 252800498 air outlet pipe fit?
A1：It is designed for XCMG ZL50G and ZL50GL wheel loaders. Confirm machine serial number before purchase to avoid wrong part selection.

Q2：What symptoms indicate the air outlet pipe needs to be replaced?
A2：Obvious exhaust noise, black smoke leaking from pipe joint, pipe wall rust through, crack on pipe body or flange weld. High-temperature gas leakage will cause power drop and may burn surrounding components.

Q3：What points should be noted during installation?
A3：Clean the flange contact surface thoroughly, use brand new sealing gasket. Tighten flange bolts evenly in diagonal sequence. After startup, check for air leakage. Do not install without gasket.

Q4：What are the main causes of damage to the exhaust pipe?
A4：Long-term high temperature oxidation, vibration fatigue causing weld cracking, external collision impact, accumulated soot corrosion, gasket aging leading to gas scouring the pipe flange.

Q5：Can small cracks on the pipe be repaired by welding?
A5：Short-term welding repair is not recommended. The pipeline works under high temperature and vibration, the repair weld is easy to crack again. High-temperature gas leakage is dangerous, better replace with new pipe directly.

Q6：How to inspect the air outlet pipe in daily maintenance?
A6：Check the pipe surface for rust, cracks and soot leakage. Check flange bolts and gasket regularly. Remove accumulated soot on pipeline surface to reduce corrosion.
