Price Guide: POA

Australia Boiler Flexible Expansion Joints Expansion Joints are used in the following locations of plant:

Fabric Joints

  • BOFA - Boost over fired air ducts
  • FGD-Flue gas desulphurisation
  • Main boiler ducting
  • Boiler penetrations and duct connections
  • Ventilation ducts

Metal Joints

  • Steam piping and penetrations
  • Oil connections
  • High pressure pipework

Australia Boiler Flexible Expansion Joints connect systems and components to provide low tension thermal expansion compensation. DEKOMTE has designed Australia Boiler Flexible Expansion Joints for numerous technically demanding environments, from extreme temperatures of above 900°C, to below 50°C.

Boiler Gas Ducts

High dust concentration in coal fired duct systems requires an innovative solution to stop the dust ingress into the expansion joint. The critical problem is temperature variance and gradients. Dust on the steel parts can cause flash and cool spots, leading to shortening the life of the joint.

3 main issues need to be overcome the highly demanding technical and environmental requirements for expansion joints in boiler gas ducts

  1. Large boiler movements
  2. High Dust content
  3. Corrosive and abrasive gases

DEKOMTE is able to provide a complete solution for the above 3 common issues

  • Multilayer fabrics
    • Internal and external installations
  • Dust Protection
    • Barriers
    • Sealing
  • By using site utility air, a sealing cushion of air can be created at the internal edge of the joint, eliminating any dust ingress and maximising life.
  • Flow protectors

DEKOMTE are different in that they have specialised design and fabrication of thermal expansion joints, which optimise the installed cost of the solution and thereby maximised the value delivered to you. As the cost of replacement of joints is typically as high as the replacement joints itself, the big benefit of having DEKOMTE is reduced maintenance costs and reduced down time (hence more revenue for the plant).
