Under what conditions should we use buried bellows expansion joints? With the increasing variety of compensators on the market, the types of pipe bellows expansion joints are also growing. However, with so many options, it can be overwhelming. Especially when it comes to the use of buried bellows compensators, when are they typically employed? Today, let's let our Chenxin team clarify this for you. The buried bellows expansion joint is primarily used to absorb axial displacement caused by thermal expansion or contraction along the axis of the buried pipeline. It is resistant to soil pressure, can self-guide, and boasts a lifespan equal to that of the buried pipeline, requiring no maintenance or replacement. The design of this product incorporates a compensation limiting structure, allowing pipeline installation without the need for guide supports. When used for transporting corrosive media through pipelines or in environments with corrosive media, a corrosion-resistant coating can be applied to the inner or outer wall of the bellows. This is a common question among many consumers and newcomers to the industry, even though some manufacturers may provide information on this topic. As for the buried bellows expansion joint, we all know it is also known as the bellows compensator. Its main function during operation is to compensate for a certain amount of displacement in the pipeline. In terms of application, it is commonly used in urban heating networks and in steam pipelines in industrial and mining enterprises, serving the purpose of compensating for displacement.

In summary, you now have a better understanding of the usage of buried corrugated compensators. If you wish to learn more about compensators, feel free to consult us. The corrugated expansion joint, also commonly referred to as a compensator or expansion joint, is composed of the corrugated tube (an elastic element) that forms the main working part, along with accessories such as end pipes, brackets, flanges, and conduits.
