What is the composition of automobile exhaust pipe

The composition of the automobile exhaust pipe: its structure is that the double-layer corrugated pipe is covered with a steel mesh sleeve, and the straight edges at both ends are covered with snap rings. In order to make the noise elimination effect better, the bellows can be equipped with expansion joints or mesh sleeves. Material: mainly stainless steel SUS304, ferrule and nozzle can be made of stainless steel or aluminized steel.
Automobile exhaust pipe is a part of engine exhaust system, mainly including exhaust manifold, exhaust pipe and muffler. The exhaust system is also equipped with three-calibration catalytic converter, which is generally used to control the emission of engine pollutants. The exhaust pipe generally includes front exhaust pipe and rear exhaust pipe.
The automobile exhaust bellows, also known as the automobile exhaust hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system can be flexibly connected, thus playing a role in reducing vibration and noise, facilitating installation, and extending the service life of the exhaust muffler system.
The main material of exhaust pipe is stainless steel. For ordinary cars, because the exhaust gas leaves the engine under great pressure, the noise it produces may make people feel crazy. At this time, the exhaust pipe of the car plays a major role in silencing. A muffler is installed inside, which greatly reduces the noise of the car. The main working principle is to divide the air flow into multiple channels. These turns only see friction and collision between each other, which gradually reduces the flow rate of the air. After repeated circulation, the exhaust gas finally flows out through the exhaust pipe of the car, reducing the noise! So as to reduce the daily car noise.
