Two Ply Exhaust Bellows

Get More Info

Two ply exhaust bellows feature two layers of thin metal formed together to create a more flexible and durable expansion joint. This dual-layer construction allows for greater movement absorption, better resistance to fatigue, and improved vibration isolation compared to single ply designs. The additional ply also provides a reinforced structure, making these bellows suitable for higher-pressure exhaust applications or systems that experience frequent thermal cycling. With their balance of flexibility and durability, two ply bellows are commonly used in marine, power generation, and industrial engine exhaust systems where moderate vibration control and movement compensation are required.
