Expansion joints are first installed on the ground. They can be installed on the ground in a simple and clear way. That is to say, there are two solutions for fixing brackets on the ground and expansion joints on the mid-range device. One type is flange connection, and the other type is to take over a connection, so that unlimited types of expansion joints can be installed, such as internal pressure type, direct pull type, direct buried type, unconstrained type, etc.

Expansion joints are the second kind of installation solution, namely, buried installation, which is enough for popular inspection to expand the installation of pipelines laid privately. There are also two ways to continuously connect with the pipeline, namely, the continuous flange and the continuous pipe, but the many days of taking over are attributed to the installation or buried installation of the expansion joint and the pipeline. There is an urgent need to install inspection wells, or you can't even think about using flanges, because after the uninspected well is installed on the inflation joint, it is impossible to expand the activity of finding refilling pipes, and the pace of pipeline damage is quickly increased. Expansion joints installed in the ground are commonly used even if they are directly buried. Their basic points are suitable for the axial alignment of directly buried pipelines, and they have bending resistance. Based on this, they agree with the influence of pipeline downward movement. The finished product has a large amount of filling and use. Long life and other characteristics.
