Model and size of expansion joint

    The model and size of expansion joints (also known as compensators) can vary depending on specific application requirements. As expansion joints are non-standard products, the following are some common expansion joint models and size ranges:

    In terms of model, the specific model of the expansion joint is usually related to its nominal diameter (DN), such as DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN400, DN500, DN600, DN800, DN1000, DN3000, DN6000, etc. These models represent the inner diameter size of the expansion joint.

    In terms of size, the size of the expansion joint not only includes the inner diameter, but also its length, flange interface size, number and diameter of bolts, etc. For example, the length of the expansion joint can range from tens of millimeters to several meters, the flange interface size can be customized according to needs, and the number and diameter of bolts will also vary depending on the size of the expansion joint and the pressure it needs to withstand.

    In addition, the model and size of the expansion joint are also related to its connection method. Common connection methods include flange connection and connecting pipe connection, which can affect the external size and installation requirements of the expansion joint.

    It should be noted that the above are only some common expansion joint models and size ranges, and specific models and sizes should be selected according to actual application needs. When choosing an expansion joint, it is recommended to consider the specific usage environment, medium, temperature, pressure, and other factors comprehensively, and consult the opinions of professionals.
