Selection of Metal Compensators for Heat Pipe Networks

    Selection of Metal Compensators for Heat Pipe Networks：

    Metal compensator, as an important pipeline connector, plays a crucial role. The editor of Zhongchuang Machinery will classify and introduce the commonly used metal compensators in the heating pipeline network, including natural compensators, corrugated pipe compensators, spherical compensators, sleeve compensators, square compensators, and rotary compensators. In order to better understand and apply these devices.

    1、 Natural compensator

    The natural compensator compensates through the bend of the pipeline itself, which is used to compensate for relatively small and later displacement.

    2、 Bellows compensator

    Large compensation amount, multiple specifications, and convenient installation and maintenance.

    3、 Spherical compensator

    With large compensation capacity, small space, and low local resistance, it is suitable for installation on long-distance overhead pipelines. But it is prone to leakage.

    4、 Sleeve compensator

    Large compensation capacity, small footprint, low fluid resistance, high thrust generated, easy leakage, and high subsequent maintenance workload.

    5、 Square compensator

    Simple structure, convenient installation, occupies a large space, and has high local resistance.

    6、 Rotating compensator

    During pipeline operation, it is in a stress free state, with long compensation distance, no internal thrust, and sealing performance.

    When selecting and applying metal compensators, the following points should be noted:

    Choose the appropriate type and specification of compensator based on factors such as the working conditions of the pipeline, medium characteristics,

 and temperature range. Different types of compensators have different characteristics such as compensation amount, sealing performance, and service life, which need to be comprehensively considered according to actual situations.

    Pay attention to the installation and maintenance of the compensator. The installation position of the compensator should be reasonable to avoid excessive stress and vibration. During use, it is necessary to regularly check the sealing and displacement parameters of the compensator to ensure its normal operation. Finally, attention should be paid to the material selection and anti-corrosion treatment of the compensator. Due to the fact that the medium in the heating network is mostly high-temperature and high-pressure steam or hot water, there is a high requirement for the material of the compensator. Generally, materials that are resistant to high temperature and corrosion should be selected, and appropriate anti-corrosion treatment should be carried out to extend the service life of the compensator.

    Metal compensator is an indispensable and important equipment in the heating network. In practical applications, appropriate types and specifications of compensators should be selected according to the actual situation, and attention should be paid to their installation, maintenance, and material selection to ensure the normal operation of the heating network.
