The height requirement of non-metallic circular expansion joint

Non-metallic round expansion joints have the characteristics of light weight and large amount of compensation are suitable for hot water, steam, starchy electrical media, through the lateral movement of non-metallic round expansion joints.
Non-metallic expansion joints should be designed to withstand pipeline displacement without damage or leakage, and can withstand the possible design of positive and negative pressure products. The non-metallic expansion joint interface size, profile size, circulation cross-section and compensation volume should meet the requirements of the demand side; it should have a good connection with the pipeline or other equipment and be well sealed; good anti-wear, anti-corrosion and sealing measures should be taken to prevent the deposition of ash and slag in the compensator.
 
Factors affecting the height requirements.
1 . The nature of the medium; according to the characteristics of the gas medium can be divided into neutral, acidic, alkaline or acid-base composite.
2 . The temperature of the medium .
3 . The pressure of the medium; generally speaking, the pressure of non-metallic expansion joints media are not more than 100kpa (0.1MPa); non-metallic expansion joints are generally applied in about 3-10KPA, in special cases can be made higher.
4 . Compensation amount; compensation amount can be requested according to the three-dimensional coordinates of the pipeline X Y Z. Generally, circular pipeline according to the axial and radial compensation requirements, rectangular according to the axial and transverse compensation requirements. Another also according to the angular displacement compensation amount requirements. Axial compensation amount refers to the expansion and contraction according to the direction of the pipeline line (i.e. airflow direction), and transverse and radial compensation amount refers to the expansion and contraction perpendicular to the direction of the pipeline line.
The inner cassette of the non-metallic circular expansion joint is connected with the pipeline, and the basic principle and internal structure of the self-pressure dynamic confinement are selected, which can be expanded and turned over in the cassette with the expansion type of the pipeline, and can adapt to the environment of any pipeline confinement clear requirements. Non-metallic circular expansion joint can ensure radial flip and also ensure that the medium does not leak out.
