technical description

general information

The flex bellows is a flexible connector made of thin-walled metal with multiple consistent convolutions. Our flex bellows are hydroformed, ensuring uniform stress distribution across the convolutions during the expansion forming process, resulting in superior flexibility.

Raw Material

The standard material of flex bellows is stainless steel 304, we also provide stainless steel 321 for some high temperature applications. Stainless steel has good high temperature resistance and corrosion resistance, and is an ideal raw material for exhaust systems. To meet the need for light weighting, titanium bellows are also an option here.

Application

Flex Bellows are designed to absorb the vibration of engine operation and the thermal expansion of piping caused by exhaust flow.

Because the engine mounts and transmission systems are quite rigid, they cannot move too much. The exhaust bellows works as an elastic vessel, and can well absorb the rock generated by the engine operation and the thermal expansion caused by the heat of the exhaust system.
