Metallic Expansion Bellows are made of metallic ingredients used in piping systems to absorb movement caused by thermal expansion and contraction. These Bellows are fixed between both the flanges and save the duct line from excessive shock and vibration. Metallic Bellow is one of the popular sub-categories of the main product – Expansion Bellow. The following can accommodate these changes without creating and putting pressure on the pipelines.

Metallic Expansion Bellows are widely used in diverse industries. It can handle high temperatures, nearly 1400 degrees and pressures. Their flexibility also helps absorb vibrations and misalignment, protecting other system components. These Bellows save pipelines when heated liquid like cement or oil passes through the pipes. Metallic Bellows are made from stainless steel, brass etc. depending on the industrial needs.
