COMPOSITE EXPANSION JOINTS

Composite Expansion Joints

Expansion joints are used to provide a point of flexibility in flue ducts, and to relieve stress caused by system movement. A composite expansion joint consists of layers of material bounded, sewn or mechanically fastened together along the edges. Each layer of material is designed to function independently of the others.

Our Effox-Flextor brand Composite Expansion Joints are engineered to deliver optimal performance and efficiency. With temperature applications from 600°F to in excess of 1500°F, and an outer later material consisting of woven fiberglass and fluoropolymer resins for chemical resistance, we confidently deliver durable and reliable solutions, while meeting your specific application needs and environmental standards.

 

Benefits of Effox-Flextor Expansion Joints

  • Low Total Cost of Ownership
  • Lower material costs
  • Minimal shipping and installation costs
  • High reliable solution for temperature applications from 600°F to 1500°F

Features of Effox-Flextor Expansion Joints

  • 6 durable layers for expansion joint maximum performance
  • Outside cover layer – fluoropolymer material which can operate in the flue duct atmosphere, and serves a gas seal
  • TFE layer – a sheet of skived PTFE that is highly resistant to chemicals and functions as a vapor (gas) barrier
  • Fiberglass / Cloth layer – Vermiculite coated fiberglass fabric acts as an insulator and provides expansion joint durability and strength
  • Insulation layer – protects the cover and the vapor barrier from heat degradation
  • Fiberglass / Cloth layer – Vermiculite coated fiberglass fabric acts as an insulator and provides expansion joint durability and strength
  • Inside Layer / Tube – Close weave material binds the belt together, acts as an insulator and gives the belt a finished appearance.
