Flue Gas Duct Expansion Joints

Metallic expansion joints round square rectangular.

Flue gas duct expansion joints.

They are used in simple cycle combined cycle co generation and coal fired power plants. 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. Rectangular metallic bellows expansion joints. Designed to your specifications and application requirements holz manufactures high quality flue duct expansion joints for industrial ductwork systems.

We off er multiple corner configurations such as radius single and double mitered and camera corner types. In industrial operations such as paper mills cement plants and steel mills. The 945 w designed flue duct expansion joint offers superior axial and lateral movement capabilities without pre compression or pre extension. Flue duct expansion joints manage air and gas handling systems for the power generation industrial institutional industries.

The holz rubber series 945 w design flue duct expansion joint is built for maximum movement. The a style expansion joint is a belt and clamp supply to be installed over the existing duct or replacement on an existing joint frame. A ducting system can be extensive and depending on what materials are flowing through having the right flue duct expansion joint is necessary to prevent leakage lessen noise and vibrations maintain operation and safety stands and reduce the chance of failure. Fabric expansion joints are used to convey hot media in low pressure applications such as in flowing air and out flowing gas in large combustion processes and also act as vibration isolators shock ab sorbers and make up for minor duct misalignments.

Flue duct expansion joints are custom designed and made to order to manage thermal expansion noise reduction vibration wind and seismic loads movement absorption and system stress relief conditions unique to each customer s site. And in institutional sites such as hospitals schools and university campuses. Flexicraft offers a full offering of quality non metallic fabric belt type and also integrally flanged fully molded type duct expansion joints for lower pressure gaseous service including high temperature flue gas. Designed for corrosive environments or elevated temperature service and accommodate axial and lateral bi directional movements in flue gas and process duct systems.

Our standard bellows are constructed of corrosion resistant stainless steel and can easily upgrade to virtually any alloy type for the conditions required. It s ideal for applications in a scrubber precipitator baghouse and stack hot air or flue gas ducts. Fabric expansion joints compensate for duct misalignment and duct thermal growth.
