Ductwork Expansion Joint Material

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.

Ductwork expansion joint material.

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. It has three main components a fabric gas seal membrane gsm insulation and metallic frames. They have outstanding resistance to chemicals oils and heat compared with other elastomers. Designs and supplies fabric or non metallic expansion joints for a wide variety of applications.

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. A fabric expansion joint is inserted into the ductwork where the movement will occur. Ductwork or ducting bellows fabric bellows or metal bellows expansion joints.

Basic forms of expansion joints. Fluoroelastomer fkm is a high performance elastomer flexible element material for fabric expansion joints and are usually reinforced with fiberglass. Rated for 400f thru 1200f. Each box of metal duct contains five 5 ft.

Fully molded duct expansion joint. 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. 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. 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.

Designed to your specifications and application requirements holz manufactures high quality flue duct expansion joints for industrial ductwork systems. Shop grainger for self sealing duct and fittings and all your hvac supplies. The fabric expansion joints can also be designed to bridge between round and rectangular ducts. Engineered with a leed qualifying zero voc gasket this ductwork can eliminate the need for additional sealing along the longitudinal seams and transverse joint.

Flue duct expansion joint flextech engineering inc. Fabric expansion joints need to be designed with many factors considered in order to ensure a long life.
