I. Core Basic Parameters
1. Factory DE Part Number: WG9925549902
2. General Name: Exhaust Pipe Flexible Connection, Exhaust Bellows, FlexibleSex metal hose
3. Compatible with model types: Heavy Duty TruckHowo TH7 and T7H National VI tractors/dumptrucks, and machines. CC11MM13 engine model
4. Material: 304 double-layer stainless steel woven mesh + corrugated inner tube, two
End stamped flange joint
5. Structure: Double-layer encrypted woven mesh,tensile resistance, heat resistance, direct installationof original factory standard flange positions
Second, the core role of the product
1. Vibration damping: Absorb engine vibrations,prevent rigid tube resonance cracking, andreduce vehicle exhaust noise.
2. Displacement Compensation: Compensates for installationmisalignment, displacement caused by thermal expansionand contraction, and prevents the exhaust pipe from breaking.
3. Sealing guide: Guide high-temperature exhaust gases and prevent exhaust leakage
Decreased power and increased fuel consumption
4. Post-protection treatment: Shock bufferingvibrations, reducing the probability of damage tothe SCR urea tank, silencer, and sensor.
Three. Replace fault scenarios
outer stainless steel woven mesh is damaged and has scattered wires.
The bellows cracked, gas leakage, and the cab has awaste odor. The vehicle is experiencing significantidle vibration and severe abnormal exhaust noise.
The original vehicle’s hose is aged, and the flange is rusted and leaking
Accident impact deformation, exhaust sealing
Four. Product Advantages
The original factory mold opening flange, holeposition, and pipe diameter fully match TH7/T7HNational VI models, requiring no modification.
Double-layer thickened stainless steel, high temperaturesabove 600°C, corrosion-resistant, salt-resistant, anddurable for long-distance construction sites
· Encrypted woven structure, resistant to filament breakage, and excellent service life
For single-layer conventional hose
· Integrated stamping flange, durable, airtight during installation, and reduced
Reduce maintenance and rework
