Unox Stainless Steel Flanged Rubber Expansion Joint

What Is a Stainless Steel Flanged Rubber Expansion Joint?

A stainless steel flanged rubber expansion joint is a type of flexible coupling used to connect pipes, tubes, or other hoses. It consists of flanges made of stainless steel at both ends for corrosion resistance and a rubber bellows in the middle that allows movement and compensates for misalignment between the connected components.

It is designed to absorb vibration, shock, and thermal expansion while accommodating slight misalignments between connected components. Stainless steel flanged rubber expansion joints are commonly used in piping systems to reduce stress at connection points and prevent leaks, especially in industries such as automotive, chemical, and food processing. They are widely used in pipe systems or equipment across various industries, including oil and gas, chemical processing, power generation, and marine engineering, to accommodate expansion, contraction, or other movements.
