Ductwork Expansion Joint Material

Fluoroelastomer fkm is a high performance elastomer flexible element material for fabric expansion joints and are usually reinforced with fiberglass.

Ductwork expansion joint material.

Flue duct expansion joint flextech engineering inc. Combination type expansion joint configuration whether the duct cross sections are round or rectan gular with rounded corners the fabric expansion joint can be designed accordingly. Ductwork or ducting bellows fabric bellows or metal bellows expansion joints. Each box of metal duct contains five 5 ft.

They have outstanding resistance to chemicals oils and heat compared with other elastomers. Microflex s metal duct type expansion joints are designed for use in low pressure ducting systems where low spring rates and high flexibility are required. Movements for a given face to face width are less than other materials. Composite flexible element material for fabric duct expansion joints are have a multi layered design with insulating layers reinforcing plies and vapor barriers with either fluoropolymer or elastomeric covers.

It has three main components a fabric gas seal membrane gsm insulation and metallic frames. A fabric expansion joint is inserted into the ductwork where the movement will occur. Designed to your specifications and application requirements holz manufactures high quality flue duct expansion joints for industrial ductwork systems. Sections for a total of 25 ft.

Basic forms of expansion joints. Ducting expansion joints will help solve problems such as. The fabric expansion joints can also be designed to bridge between round and rectangular ducts. Ducting and low pressure expansion joints are lightweight flexible connectors designed for gaseous media made out of natural or synthetic elastomers with combinations of rubber and fabric reinforcement especially for scrubbers precipitators baghouses and fans in air handling systems.

As the ducting moves the gsm will deform without tearing or leaking while being exposed to high tempera tures and corrosive media. Engineered with a leed qualifying zero voc gasket this ductwork can eliminate the need for additional sealing along the longitudinal seams and transverse joint. 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. Pressures typically less than 5 psig and high temperatures to 1500 f 1 0 sizes to 16 0 sizes round or rectangular any length anything shippable handling clean or dirty air streams gas streams or flue gas streams.

Rated for 400f thru 1200f. Designs and supplies fabric or non metallic expansion joints for a wide variety of applications.
