Fabric, metalic and rubber expansion joints are primarily used for gaseous fluids.

Assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, to hold certain parts together, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of sidewalks, bridges, railway tracks, ducting and piping systems, ships, and other structures.

Throughout the year, building faces, concrete slabs, ducts and pipelines will expand and contract due to the warming and cooling through seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced.

This overall definition of “Expansion joints” covers a wide range of products. As underlined above, SEIRIS is specialized in Ducts and Pipelines applications. SEIRIS is present in any kind of heavy industries where we can find FABRIC, METAL and RUBBER expansion joints.
