Structural Features
The direct-buried expansion joint is also known as buried compensator, direct-buried compensator, and directly-buried bellows. They have the characteristics of compact structure, less space, and only axial deformation. They are suitable for pipelines with only axial displacement. in. It has the ability to compensate the lateral displacement and the combined axial and lateral displacement.
It is mainly used for the axial compensation of directly buried pipelines. It has the ability to resist bending, so the influence of pipeline sinking can be ignored. The product has the characteristics of large compensation and long life.
