Abstract

The invention provides an exhaust pipe. The exhaust pipe comprises an exhaust pipe body and a connecting part. A filter screen is arranged in the exhaust pipe body. The exhaust pipe body and the connecting part are welded together. A through hole is formed in the exhaust pipe body in the axial direction. An oil inlet is formed in the middle of the exhaust pipe body. The oil inlet communicates with the through hole. The exhaust pipe is simple in structure, and manufacturing of the exhaust pipe is convenient.

Description

technical field [0001] The invention relates to an exhaust pipe and a method for manufacturing the exhaust pipe. Background technique [0002] Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, and is convenient. The function of installing and prolonging the life of the exhaust muffler system. It is mainly used for light vehicles, miniature vehicles and passenger cars. Its structure is that the double-layer bellows is covered with steel wire mesh sleeves, and the straight edge sections at both ends are covered with snap rings. In order to make the noise reduction effect better, the bellows can be equipped with telescopic knot or netting. Material: The main material is stainless steel SUS304, and the ferrule and connecting pipe can be made of stainless steel or aluminized ...
