The small rod horizontal expansion joint consists of two bellows separated by a pipe section and several limit rods which can not withstand the internal pressure. This expansion joint can compensate for the lateral displacement of curved pipe sections and angular displacement, and can compensate for axial displacement. After installation, loosen the curtain and keep it a certain space from the ear piece.
