GRP Chimney & Flue

Grp (glass reinforced plastic) or frp (fiber reinforce plastic) chimney and flue
hbfs can design, supply, assemble and install chimney or flue at plants. We are experienced in providing chimney or flue to all local and international markets, such as the power market for the fgd and ccs processes. Chimney or flue can be manufactured on site or in one of our workshops. We assemble ducts from the absorber to the chimney or cooling water tower. Hbfs supplies ducts from different diameters, while our onsite winding machine can deliver ducts of 18 meters in diameter.
Hbfs ducts are often used to transport gases from one process to the other. The chimney liners also transport gases to a higher level where it can be released to the environment without harming or having a major impact on the local environment.
Hbfs designs and construct the ducts, chimney liners and stacks by using the finite element method (fem analysis) to meet the highest requirements and ensure a perfect quality and safety product.
Hbfs has designed products for application at a temperature of 220˚c.
Advantages of using grp (frp) ducts:
1.high mechanical strength
2.low weight
3.exceptional chemical resistance
4.excellent resistance to ageing and to atmospheric environments
5.dimensional stability
6.very high thermal insulation
7.excellent resilience to temperature
8.low thermal expansion coefficient
ducts can be executed with:
1.90° elbow with internal vanes
2.segmented elbow
3.transition pieces
4.ladders and condensate drainage
5.protection against electrostatic discharge
6.manholes
