Metallic Expansion Joint

Metallic Expansion Joint Product Information

Bellows expansion joint is normally known as damping bellows compensator or bellows joint, which is mainly made up of bellows, flanges, bellows ends and tie rod. Bellows expansion joints is one type of compensator, which is normally used to make up for axial movement. Although it can also make up for Agular movement, it’s not normally used in the actual working conditions. We can manufacture and supply the bellows expansion joints according to ANSI, JIS, DIN, BS standards with sizes of 1-1/4”~40” (DN32~DN1000mm).
