Manufacturing Technology And Advantages Of Bellows Bellows, which sounds like the name of future technology products, has actually played an important role in our lives. The bellows are installed in the exhaust pipe between the engine exhaust manifold 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. The bellows can also be used as compensators to bear the transmission of liquid and gas in the case of thermal expansion, cold contraction or vibration, maintain the stability of the pipeline system, ensure the stability of the pipeline system, and smooth fluid transmission. As a tubular component with unique structure, it has the advantages of high strength, corrosion resistance, wear resistance, high flexibility and bending properties, and has been widely used in many fields such as automobile and chemical industry.
