Metal bellows expansion joint

Composition and working principle: The flexible device composed of two bellows connected by the middle and indirect pipes, tie rods, end plates, etc., compensates the thermal displacement of the plane or three-dimensional curved pipe section by means of lateral displacement. The tie rod device should be able to withstand the pressure thrust and its accessories The role of external forces. Compound tie rod type expansion joints are particularly suitable for absorbing lateral displacement. In addition, this design form can also be used to absorb axial displacement, angular displacement and any displacement combined by these three forms. The general usage is to set this type of expansion joint with tie rods. In the middle pipe wall of the 90° "Z"-shaped pipe system, adjust the pull rod to prevent the external axial displacement.
