Introduction: Bellows compensator is a kind of pipe compensator widely used in recent ten years. In recent years, this new compensator has been widely used in many fields in China. The bellows compensator used for directly buried heating pipeline compensation is easy to install

corrugated pipe Compensator It is a kind of pipeline compensator widely used in recent ten years. In recent years, this new compensator has been widely used in many fields in China. For compensation of directly buried heating pipeline Bellows compensator Compared with the traditional compensator, it has obvious advantages because of its easy installation, small volume, small occupation area and large compensation. So about direct burial Corrugated compensator Design and installation in practical application environment
What problems should we pay attention to? The following by Shanghai Luoying water treatment equipment Co., Ltd. installation and maintenance personnel to give you a brief introduction.
The following four points should be noted:
First, due to the different compensation methods of various directly buried bellows compensators, their production, processing, selection and installation are quite different. Before choosing the directly buried bellows compensator, it is necessary to determine what kind of compensation method should be adopted and make relevant calculation according to the requirements of compensation mode.
Second, the compensation of directly buried bellows compensator can be calculated according to the layout of overhead or underground pipelines. But in fact, there is a difference between directly buried pipeline and overhead pipeline or in trench. Due to the direct burial of the pipeline, the friction between the pipeline and the backfill (sand) is increased, so that the bearing force of the two fixed supports is transformed into one component force applied on the fixed support and the other component force applied to the pipeline. In this way, it is necessary to check whether the stress borne by the pipeline exceeds the allowable stress of the pipeline, especially at the turning point of the pipeline. In addition, the compensation of the compensator can also be selected according to the lower limit.
Third, from the structure of directly buried bellows compensator, it can be seen that most bellows compensators are equipped with diversion sleeves, which are mainly used to reduce the flow resistance of medium. However, the guide sleeve has direction, if the installation direction is not correct, it will not play a guiding role. Therefore, it is necessary to pay attention to the direction of the guide sleeve, especially when the bellows compensator of the water supply and return pipe is installed in a relatively parallel position, the water flow direction of the supply and return water is opposite, and it is easy to make mistakes.
Fourthly, the setting position of bellows compensator in directly buried pipeline should be changed according to different compensation methods. Only one bellows compensator is installed between two fixed supports. The one-time directly buried bellows compensator should be set in the middle of the two fixed supports; the location of the free compensation direct buried bellows compensator should be close to one of the two fixed supports and away from the other.
It can be seen from the above points that the directly buried bellows compensator as a new type of pipeline compensation device has a broad development prospect. With the popularization of the design and manufacture of the bellows, it is necessary to popularize the design and installation of the bellows.
