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.


So how is the bellows made? What are its advantages? This paper will introduce the manufacturing process and advantages of the bellows in detail.

· Manufacturing process of bellows


The production process of bellows can be described as a technical work. First of all, according to different application environments and requirements, choose the right materials, such as high-quality stainless steel, carbon steel, aluminum and other metal sheets as raw materials. Then according to the customer's design requirements, the corrugated shape and size of the tube blank are customized, and the metal material is made into the tube blank with corrugated by cold drawing or cold rolling. Then the finished tube blank is seam welded. During the welding process, it is necessary to ensure that the weld is uniform and firm, and there is no leakage or virtual welding. In order to improve the corrosion resistance of the bellows, it is usually necessary to carry out surface treatment, such as galvanized, spraying and so on. Finally, a series of inspections and tests are carried out on the bellows to ensure that their quality meets international standards.

· Advantages of bellows


In general, the bellows are more beautiful than ordinary bellows, the style is more beautiful, the lines are smooth, and the decorative effect is certain. In construction, decoration and other fields, bellows can be used as part of the pipe system to improve the overall beauty. The work is more complex, involving more molds, the lining needs to be stamped, the wave number, waveform, wave height, the lining should be matched, the internal flow tube, and the product needs to be ground welded and polished, which is more durable and stronger than ordinary bellows.


Specifically, compared to other types of pipe materials, the bellows have the following advantages:


1. High strength and high flexibility: The bellows are made of high-quality metal materials, with high strength and toughness, can withstand greater pressure and impact force, and are not easy to break. Can adapt to different installation environment and pipeline layout, easy installation and maintenance.


2. Corrosion and wear resistance: The surface of the bellows has been specially treated and has good corrosion resistance, which can be used in harsh environments such as acid, alkali and salt for a long time and is not easy to rust. And its inner wall is smooth, not easy to accumulate scale, can reduce the resistance of the fluid, reduce the wear of the pipeline, extend the service life.


3. Space saving: The bellows adopt corrugated design and have good elasticity, which can alleviate the thermal expansion and cold contraction of the pipeline to a certain extent and save the installation space of the pipeline.
