FRP Duct System

Many coal-fired power stations in Europe and the USA have been equipped with fiberglass (FRP) duct systems, manufactured and assembled by Plasticon Composites International Contracting. Specially for the Flue Gas Desulphurization units, refurbishing and new stations, our fiberglass ducts have proven to be the best choice. New duct systems as well as temporarly bypass systems with high temperatures can be supplied by our group. Not only is a fiberglass duct easy to assemble, it is lightweight, mechanical strong and has excellent corrosion resistant properties.

Fiberglass ducts up to 12 meters diameter

The team of Plasticon Composites International Contracting is a full-service supplier when it comes to fiberglass duct systems for power industries. From the design to engineering, stress analysis to manufacturing onsite and assembly phase: we can to the job! With our on site winding facilities we are able to produce a variaty of diameters up to 12 meter diameter and manage the total assembly from the absorber to the chimney or cooling water tower. Our project management skills are well developed and efficiency is our main competence.

Resistance to high temperatures

Fiberglass ducts are used to transport gases from one process to the other, high temperatures and chemical components are applicable. Our FRP duct systems could be used for application at a temperature of 300˚C and as FRP is 100% resistant to corrosion and all types of chemical fluids or gasses. 

Plasticon Composites International Contracting designs and constructs ducts, chimney liners and stacks by using the Finite Element Method (FEM analysis) to meet the highest requirements and ensure products of perfect quality and safety.

Advantages of FRP ducts:

  • High mechanical strength
  • Lightweight (steel ducts are five times as heavy!)
  • Exceptional chemical resistance 
  • Excellent resistance to ageing and to atmospheric environments
  • Dimensional stability
  • Very high thermal insulation
  • Excellent resilience as regards temperature 
  • Low thermal expansion coefficient

Ducts can be executed with:

  • 90° Elbow with internal vanes
  • Segmented elbow
  • Transition pieces
  • Ladders and condensate drainage
  • Protection against electrostatic discharge
  • Manholes
