About Round Rubber Bellows
Round rubber bellows have a unique corrugated shape. This tubular structure can be used in various industrial fields, such as chemicals, petroleum, pharmaceuticals, etc., as seals, connectors or protective sleeves, etc., making it an ideal choice in the industrial field.
Advantages
1. Strong corrosion resistance: The round rubber bellows is made of high-quality rubber material and has good corrosion resistance. Whether it is acidic, alkaline, oily or aqueous media, circular bellows can maintain stable performance and are not corroded by chemicals.
2. Good wear resistance: The corrugated shape design of the circular bellows makes it have excellent wear resistance. In high-pressure, high-friction environments, circular rubber bellows can maintain stable sealing performance and reduce leakage and wear.
3. Excellent sealing performance: The sealing performance of round rubber bellows is one of its most important advantages. It can effectively prevent gas or liquid leakage and ensure the safe operation of equipment. At the same time, its sealing performance is stable and not easily affected by factors such as temperature and pressure.
4. Good flexibility: The round rubber bellows has good flexibility and can maintain shape stability and integrity even when bent or twisted. This feature makes it perform well in some complex application environments, such as curved pipes, valves, etc.
Application
1. Chemical industry: In the chemical industry, round rubber bellows are widely used in piping systems, valves, pumps and pipe fittings. With its excellent corrosion resistance and sealing performance, it provides guarantee for the normal operation of chemical equipment.
2. Petroleum industry: In the petroleum industry, circular bellows are widely used in wellhead equipment, pipeline systems, etc. It resists corrosion and leakage of oil and natural gas, improving safety and efficiency during oil extraction and transportation.
3. Pharmaceutical industry: In the pharmaceutical industry, round rubber bellows are widely used in pharmaceutical production equipment, pipeline systems, etc. Due to its corrosion resistance to various chemicals used in the pharmaceutical production process, the quality and safety of pharmaceuticals are guaranteed.
4. Other fields: In addition to the above-mentioned industries, circular rubber bellows are also widely used in electric power, food, water treatment and other fields. Its excellent corrosion resistance, wear resistance and sealing properties make it a versatile industrial material.
Certification
1. Pressure resistance performance certification: The round rubber bellows has been tested for pressure resistance performance to ensure that it can maintain stable sealing performance in a high-pressure environment. Testing usually involves holding pressure at a specified pressure for an extended period of time to see if the seal leaks or deforms.
2. Corrosion resistance certification: The circular bellows has been tested for corrosion resistance to verify its stability in various chemical media. Testing typically involves soaking rubber bellows in a specific chemical solution and observing whether it exhibits corrosion, discoloration or performance degradation.
3. Wear resistance performance certification: The rubber bellows has been tested for wear resistance to verify its wear resistance in high friction environments. Testing usually involves conducting a friction test under a specified friction force to observe whether the rubber bellows is worn or deformed.
4. Dimensional stability certification: The round rubber bellows has been tested for dimensional stability to ensure that it maintains stable size and shape during long-term use. Testing usually involves long-term aging tests under specified temperature and humidity conditions to observe whether the rubber bellows exhibits dimensional changes or deformation.
In short, the certification for use of circular rubber bellows requires multiple aspects of testing and evaluation to ensure that it has excellent pressure resistance, corrosion resistance, wear resistance, dimensional stability and environmental protection performance. These certifications ensure reliable performance and safety of round rubber bellows in a variety of applications.
