What is exhaust bellows?

Automobile exhaust bellows are also called automobile exhaust pipe hoses. Automobile exhaust bellows are installed in the exhaust pipe between the engine exhaust branch pipe and the muffler so that the entire exhaust system is flexibly connected so that the automobile exhaust bellows can reduce vibration and reduce vibration. The role of noise, easy installation, and prolonging the life of the exhaust muffler system. So what is the specific role of automobile exhaust bellows?

Introduction

Automobile exhaust bellows are mainly used in light vehicles, mini-cars, and passenger cars. Its structure is a double-layer corrugated tube covered with a steel wire mesh sleeve, and the two ends of the straight side section are jacketed with snap rings. The automobile exhaust bellows are used to make the noise reduction effect better. Exhaust bellows can be equipped with expansion joints or net sets inside. Material: The main material of automobile exhaust bellows is stainless steel SUS304, and the material of the ferrule and tube of automobile exhaust bellows can be stainless steel or aluminized steel. The open end of exhaust bellows is fixed, the sealed end is in a free state, and the auxiliary exhaust bellows coil spring or reed is used to increase the elasticity.

Car exhaust bellows play a role in reducing vibration and noise and prolonging the life of the exhaust muffler system. The main material of automobile exhaust bellows is stainless steel. For ordinary car exhaust bellows, because the exhaust gas of the car leaves the engine under a lot of pressure, the noise it produces may make people feel crazy. At this time, the main noise reduction function is the car exhaust bellows, and the noise reduction is installed inside it. It greatly reduces the noise of the car. The main working principle of automobile exhaust bellows is to split the airflow through multiple channels. This exhaust bellows only see mutual friction and collision, which makes the flow rate of the exhaust bellows airflow gradually decrease. Such repeated cycles finally make the exhaust gas flow out through the exhaust bellows of the automobile, which reduces the noise.Car exhaust bellows thus achieve the effect of reducing noise in daily cars.

 

The material of choice for automobile exhaust bellows.

1) Automobile exhaust bellows ferritic stainless steel contains no or less precious metal Ni, and the raw material cost is low;

2) Automobile exhaust bellows ferritic stainless steel has small thermal expansion coefficient, high thermal conductivity, good high-temperature oxidation resistance under repeated heating and cooling conditions, and good corrosion resistance;

3) Compared with austenitic stainless steel, automobile exhaust bellows ferritic stainless steel has good resistance to chloride, stress corrosion, and intergranular corrosion;

4) Ferritic stainless steel has low resilience during cold forming of automobile exhaust bellows.
