Which Materials of Bellows Are More Durable?

1. Metal bellows: Metal bellows are usually made of stainless steel, nickel alloy, titanium alloy and other materials, with high corrosion resistance and mechanical strength, and long service life. Among them, stainless steel bellows are widely used in medical, chemical, food and other fields because of their good corrosion resistance and sanitary performance.

2. Plastic bellows: plastic bellows are usually made of polyethylene, polypropylene, polyvinyl chloride and other materials, with good corrosion resistance and portability, mainly used for transporting acid, alkali, salt and other corrosive media. Among them, high-density polyethylene bellows and polypropylene bellows are widely used in chemical industry, environmental protection and other fields.

3. Glass fiber reinforced plastic bellows: This bellows is made of glass fiber reinforced plastic, has high strength and corrosion resistance, and is suitable for conveying corrosive media. Because of its light weight and corrosion resistance, it is also widely used in chemical, environmental protection and other fields.

4. Rubber bellows: rubber bellows are usually made of natural rubber, synthetic rubber and other materials, with good corrosion resistance and sealing properties, mainly used for transporting various corrosive media and high pressure gases. Among them, fluorine rubber bellows are widely used in chemical industry, petroleum and other fields.

In summary, metal bellows, plastic bellows, glass fiber reinforced plastic bellows and rubber bellows and other materials are relatively durable, and the specific choice of which material of bellows should be determined according to the actual application scenario and use environment.
