Product Description

 

Product Description

 

Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust pipe and the muffler, so that the entire exhaust system is flexible connection, so as to reduce vibration and noise, convenient installation and extend the life of the exhaust muffler system. It is mainly used in light vehicles, minicars and buses, its structure is a double-layer corrugated pipe covered with wire mesh, both ends of the straight edge section of the outer ring structure, in order to make the sound reduction effect is better, the corrugated pipe can be equipped with expansion joints or mesh sleeves. Material: The main material is stainless steel SUS304, the bushing and nozzle material can be stainless steel or aluminum plated steel.

Our Advantages

 

Advantage:
1. Reduce vibration and noise: exhaust pipe bellows can eliminate pressure waves and vibration inside the exhaust pipe, thereby reducing noise and vibration and improving driving comfort.
2. Improve exhaust efficiency: the exhaust pipe bellows can reduce the resistance of the exhaust pipe and improve exhaust efficiency, thereby improving the performance and fuel economy of the car.
3. Protect the exhaust system: the exhaust pipe bellows can reduce the vibration and pressure waves of the exhaust pipe, thereby reducing the damage and wear of the exhaust system and extending the service life of the exhaust system.

 

 

Product Parameters

Parameter	Typical range	Remark
Diameter (inside diameter)	50-150mm	According to the engine displacement matching, such as cars commonly used Φ60-100mm
length	100-300mm	Depending on the axial compensation requirement, the short type is mostly used in the integrated design of post-processing.
Number of ripples	3-15 ripples	The higher the wave number, the stronger the flexible deformation ability, but it may reduce the pressure resistance
Wall thickness	0.5-2.0mm	Temperature and pressure environments (such as diesel vehicles) require thicker walls

 

Installation Instructions

 

Factors affecting the size of bellows
1. Engine displacement and power
• Large displacement engines (e.g. 3.0L and above) usually require a larger diameter bellows (e.g. Φ80-150mm) to match the higher exhaust flow.
• Small displacement engines (e.g. 1.0L-2.0L) have smaller bellows in diameter (e.g. Φ50-80mm).
2. Exhaust system design
• Space limitations: Models with a compact chassis layout may have a folding or shorter bellows.
• Pressure resistance requirements: High-performance models (such as turbocharged engines) require bellows with higher pressure resistance, which may be accompanied by greater wall thickness or special construction.
3. Temperature and environment
• Bellows in high temperature areas (such as near the engine) require thicker stainless steel, which may affect their outside diameter and length.
