    Directly embedded bellows expansion joints Because the axial stiffness of the bellows expansion joint is small, the axial force generated by the internal pressure of the pipeline often affects the design and use of the piping system. The axial force is transmitted to the bellows expansion joint in the piping system without any constraint, called a free-type (unbalanced) bellows expansion joint; the axial force is restricted by some mechanisms or devices and cannot be transmitted to the bellows expansion joint. It is called a balanced bellows expansion joint. The balanced bellows expansion joint is divided into two types: a damper type and an absorbing type: a bellows expansion joint that prevents axial force transmission by using a member such as a tie rod or a hinge, which is a damped type; and a balanced bellows expansion joint is realized by using the working pressure itself, Absorption type.
