FRP/GRP FGD Piping
Flue gas desulfurization systems operate under extremely aggressive, abrasive, and continuously wet conditions, making material selection critical for long-term performance. In any fgd system or fgd plant, piping networks are exposed to limestone or lime slurry circulation, gypsum formation, acidic condensates, and particulate-laden fluids generated during SO₂ removal. These demanding environments are commonly encountered in fgd in power plant applications as well as in fuel gas desulfurization and desulfurization of natural gas processes.
FRP/GRP solutions are specifically engineered to withstand these conditions, making fgd pipes, fgd grp piping, and fgd frp piping a superior alternative to conventional metallic systems that deteriorate rapidly. SREX Composites manufactures high-performance flue gas desulfurization frp pipes, flue gas desulfurization grp pipes, along with flue gas desulfurization frp fittings and flue gas desulfurization grp fittings, ensuring complete flue gas desulfurization frp pipes and fittings and flue gas desulfurization grp pipes and fittings solutions for absorber circuits, slurry handling, recirculation loops, and oxidation air systems.

FGD Operating Characteristics
FGD environments present unique operational challenges across every fgd scrubber and piping network:
- Continuous exposure to acidic, chloride-rich condensates
- High-solid slurry containing limestone, gypsum, and particulates
- Severe erosion and abrasion due to slurry movement
- Temperature variations and cyclic operating conditions
- Requirement of uninterrupted operation with minimal downtime
FRP/GRP piping maintains structural integrity, corrosion resistance, and erosion tolerance, making it ideal for long-term service in these harsh conditions.
FGD Piping Application Areas
Across every fgd plant, FRP/GRP piping is widely used in:
- Absorber and fgd scrubber circulation lines
- Slurry recirculation and pump suction/discharge lines
- Limestone and gypsum slurry transport
- Mist eliminator wash systems
- Oxidation air piping
- Blowdown, drain, and overflow lines
- Filter feed and return pipelines
- Reagent preparation and handling systems
Integration of fgd frp piping and fgd grp piping ensures lightweight installation, corrosion resistance, and reduced lifecycle maintenance.
Performance Advantages (FGD-Specific)
- Corrosion Resistance: Withstands acidic condensates and chloride exposure
- Erosion Resistance: Designed for abrasive slurry environments
- Lightweight Construction: Reduces structural load and installation complexity
- Long Service Life: No rusting, scaling, or wall thinning
- Hydraulic Efficiency: Smooth internal surface minimizes deposition
These advantages establish FRP/GRP as the preferred material for modern flue gas desulfurization systems worldwide.

- Steel and metallurgical off-gas treatment
The spray system is one of the most critical components inside any fgd scrubber. In a typical fgd system, spray headers ensure uniform slurry distribution, which is essential for efficient SO₂ absorption. These systems operate in highly corrosive, high-moisture, and abrasive environments.
SREX Composites manufactures advanced frp fgd spray header, grp fgd spray header, frp spray bank, grp spray bank, frp fgd spray bank, and grp fgd spray bank systems engineered specifically for absorber tower applications.
