Duct & Expansion Joints Repair

An expansion joint is a mid-structure separation designed to absorb vibration, join objects, or allow movement. It is commonly located on structures such as bridges, highways and sidewalks. These expansion joints are used to add flexibility to industrial ducting systems and fan/blower connections to absorb thermal growth, isolate vibration and noise, and allow for misalignments. Their large movements in a given space, small spring rates, and large temperature range give them advantage not available with other types of joints. They are needed in a wide array of industries, including power, petrochemical,pulp & paper, along with countless other industrial facilities.

In structures, expansion joints can help absorb the expansion and contraction of concrete slabs as a result of temperature changes. Without expansion joints, the concrete can crack or distort. However, expansion joints on their own are susceptible to failure. A major issue is incompressible materials that lock the joints and create stresses that may cause concrete spalling or shattering.

Through the years TecRadon has carried out countless Expansion Joint Repairs on heavy steel constructions in carbon steel or stainless steel, such as thick walled welding ends, thick walled flanges and other hardware like gimbals etc.
