Composed of a metal bellows and flange, which can compensate the pipeline’s axial, lateral and angular displacement by thermal and mechanical deformation, and absorb a variety of mechanical vibrations, to reduce distortion and prolong the pipeline’s service life;

U-shaped, Ω-shaped, S-shaped, V-shaped, divided by structure, U-shaped is popular;

Mainly used to compensate for axial or lateral displacement
