The Temperature Range Of Pe Gasket


    Important factors affecting the selection of Pe Gasket selection is not an easy task, especially in the selection of gasket sealing materials, many factors must be considered. The variables appearing at the flange connection seem to be endless, and all these uncertain factors affect the sealing effect of the gasket. In the past, the parameters "TEMP" (temperature, application, medium, pressure) seemed to be sufficient. Therefore, various parameters must be considered comprehensively to make an appropriate choice.
    1. Temperature: In most of the selection process, the temperature of the fluid is the primary consideration. This will quickly narrow the selection, especially from 200°F (95°C) to 1000°F (540°C). When the system operating temperature reaches the limit of the maximum continuous operating temperature of a particular gasket material, a higher-level material should be selected. This should also be the case under certain low temperature conditions.

    2. Application: The most important parameters in the application are the type of flange and the bolts used. The size, number, and grade of bolts in the application determine the payload. The effective area to be compressed is calculated from the gasket contact size. The effective gasket sealing pressure can be derived from the load of the bolt and the contact surface of the gasket. Without this parameter, you will not be able to make the best choice among many materials.

    3. Medium: There are thousands of fluids in the medium, and the corrosiveness, oxidation and permeability of various fluids vary greatly. The selection of materials must be based on these characteristics. In addition, the cleaning of the system must also be considered to prevent the erosion of the gasket by the cleaning fluid.

    4. Pressure: Each type of gasket has its highest ultimate pressure. The pressure-bearing performance of the gasket decreases with the increase of the material thickness. The thinner the material, the greater the pressure-bearing capacity. The selection must be based on the pressure of the fluid in the system. If the pressure fluctuates frequently, you need to know the details to make a choice.

    5. PT value: The so-called PT value is the product of pressure (P) and temperature (T). The pressure resistance of each gasket material is different at different temperatures and must be considered comprehensively.
