Characteristics and selection requirements of double flange limit expansion jointDouble flange limit expansion joint is a kind of equipment widely used in pipeline connection, which has the function of limit and expansion, which can protect the pipeline from mechanical stress and temperature changes. When selecting and using double flange limit expansion joints, the following key characteristics and selection requirements need to be considered:
1.Material: The material of the double flange limit expansion joint should match the material of the pipe to ensure good connection and corrosion resistance. Commonly used materials include carbon steel, stainless steel, alloy steel, etc.
2.Expansion capacity: Double flange limit expansion joints have different expansion and expansion amounts to meet the needs of pipes with different lengths and temperature changes. When choosing, the appropriate expansion and contraction amount should be selected according to the design length of the pipeline and the usage environment.
3.Limit function: The double flange limit expansion joint has a limit function, which can limit the displacement and vibration of the pipeline and prevent excessive deformation or damage to the pipeline. When choosing, joints with good limit performance should be selected to ensure the safe operation of the pipeline.
4.Pressure Ratings: Double flange limit expansion joints are available for different pressure classes, including low, medium and high pressure. When choosing, the appropriate joint should be selected according to the pressure level of the pipeline to ensure its stability and safety.
5.Environmental adaptability: Double flange limit expansion joints should have good environmental adaptability and be able to work normally in different temperature, humidity and corrosive environments. When choosing, the environmental adaptability of the joint should be considered to ensure its long-term stable operation.
To sum up, the double flange limit expansion joint is an important pipe connection equipment, which has a variety of characteristics and selection requirements. When selecting and using, it should be comprehensively considered according to the actual needs and pipeline conditions to ensure its performance and safety.
