Flextech Engineering, Inc. designs and provides fabric expansion joints (or non-metallic expansion joints) for each individual application. Fabric or non-metallic expansion joints need to be designed so that an impermeable seal is maintained between the flue gas and the outside air. These factors include:
  • thermal motion
  • structural offset
  • abrasive conditions
  • acidic media
  • extreme temperatures
  • vibration
  • moisture build-up
  • pressure

Each expansion joint needs to be made with these in consideration. If the expansion joint is made to the proper specifications, it will be optimal for application.

Flextech Engineering, Inc., designs and builds each expansion joint to meet the customer's unique application, including the framing, insulation pillows and baffle plate arrangement.

The following expansion joint styles are a sampling of the basic types available. Many additional customized expansion joint styles are also available.
